Hannover FAIR 2016
Electric drives –
Essential links in the
process chain 4.0
In 2016, the focus of the Hannover
Fair and its flagship exhibition
“Industrial Automation” is to be
placed on the future course of the
fourth industrial revolution. The way
ahead is the digital networking of all
industrial processes.
On our fair stand, you can experience
how VEM, as a supplier of
complete drive systems, is preparing
for the challenges under the
motto „ELECTRIC DRIVES FOR
EVERY DEMAND“.
Visit us from 25 th to 29 th April
2016 in Hall 14, Stand H 10.
The roots of electrical
engineering at VEM can be
traced back to 1886. It was in
that year that work began to
establish the original Sachsenwerk
factory.
Engineer Ludwig Oskar Kummer
pioneered the development of
electrical engineering in Niedersedlitz
during the 1880s. The
plot of land which he acquired,
The historical motor designed
by O. L. Kummer
at that time still before the gates
of Dresden, was deemed the
ideal site for the manufacturing
of electrical machines. In 1886,
and thus exactly 130 years ago,
Kummer received important post
from the Royal Saxon Trading
Standards Office: Building permission
for a factory to manufacture
equipment and machinery
operated by electricity. It was
not long before industrial-scale
production began to flourish,
and the factory can be seen as
a cradle of electrical engineering
in Europe.
When we view the portfolio of
VEM‘s Dresden location today,
we find not only large machines,
generators and drive systems,
but also a number of motors
which uphold the age-old traditions
of motors from Sachsenwerk
in the most striking manner.
Traction motors for trams, for
example. Already a century
ago, Sachsenwerk supplied
such motors to Allenstein (today
Olsztyn/Poland), and history was
repeated with further deliveries to
the Polish city – in new design, of
course – in 2015 (see also page
3). Longstanding experience is a
basis for reputation and promotes
A modern pump drive from
VEM Sachsenwerk
customer loyalty. No less so than
quality, expertise and the readiness
to respond flexibly to customer
wishes.
The other locations of the VEM
Group also score with decades
of experience in their respective
fields. The manufacturing
of electric motors in the region
around Zwickau, for example,
dates back almost 110 years; it
was in 1908 that brothers Kurt and
Alfred Stephan set up the electrical
workshop which later evolved into
VEM motors Thurm. In Wernigerode,
the first electric motors were
produced in 1947. The company
will thus be celebrating its 70 th
anniversary next year.
The history of the VEM company
Keulahütte GmbH in Krauschwitz
must be counted in centuries
rather than decades. Today, it
is a modern, high-performance
supplier of the most diverse cast
products. But with traditions stretching
back more than 500 years,
it is at the same time one of the
oldest iron foundries in Germany.

Transport engineering
In Olsztyn number one since 100 years
Sachsenwerk in Dresden. Tram
services were discontinued in
favour of buses in 1965. Since
last year, however, they have
experienced a renaissance with
the development of a new route
network.
Today’s visitors to Olsztyn can
travel the city aboard a fleet of
modern low-floor trams. A total
of 15 new trams were supplied
by manufacturer Solaris by the
end of 2015. They are each
driven with DKCBZ 0210-4D
120 kW traction motors from
Sachsenwerk. In this way, more
than 100 years after the original
deliveries, proven drives from
the VEM location in Dresden
have found their way back to the
Warmian-Masurian capital – this
time as an example from the
comprehensive range of products
which VEM has tailored to
the demands of modern railborne
vehicles and the transport
branch as a whole.
Trams in the Polish city of Olsztyn were first equipped
with Sachsenwerk traction motors over a century ago.
Today, history is repeating itself.
They were no doubt much louder, but their design
was in keeping with street scenes in the early 20 th
century and they gave reliable service: Trams in what
was then the German city of Allenstein, today Olsztyn
in the north-east of modern-day Poland. Already
when the first line was opened at the end of 1907,
the cars were driven by DC traction motors from

Improved annealing process
Test installation of the Carbojet® gas control
panels for setting of the nitrogen and hydrogen
flow rates
New heat treatment technology
brings valuable benefits for VEM
in Wernigerode
At VEM in Wernigerode, electrical steel
sheet is annealed in a roller hearth furnace
with a throughput capacity of 2.5 tonnes per
hour. Especially where Si-alloyed electrical
strip steels are used, the tempering process
was often found to be rather problematic.
Not least for that reason, it was decided
to seek significant improvement of the
annealing process with the aid of the Linde
CARBOJET® technology. The technology
is based on high-speed gas injection. It
optimises the flow characteristics of the
injected gases and provides for more complete
mass transfer in the furnace.
The results are beneficial for both the
customer and the manufacturer. The new
technology not only improves the tempering
process and thus the quality of the
annealed sheet. The reduced energy and
material consumption also eases the impact
on the environment.

Research & development
VEM generators for GeCoLab

Preparations for an arc flashover test at the German
High-Power Test Laboratory (IPH)
Engineering
Leibniz University in Hannover installs a
megawatt-class universal test stand to
aid research and development
The GeCoLab large-scale test stand is a
government-funded project of the Institute
of Drive Systems and Power Electronics
(IAL) at the Leibniz University in Hannover.
The test stand was officially inaugurated
on 11 th January 2016.
As supplier of the two generators, the
VEM location in Dresden has contributed
significantly to the success of the project.
In addition to a double-fed asynchronous
generator of the type typically incorporated
into wind turbines, a permanent-magnet
synchronous machine was developed
specifically for the test stand. In response
to customer wishes, the latter was also
fitted with a multitude of sensors on both
the stator and rotor.
The new test stand offers diverse possibilities
for analytical experiments and will
enable the scientists at IAL to study the
frequently neglected interactions between
generators and converters. With an output
rating of up to 1.5 MW, it covers a wide
range of relevant applications, for example
testing on 1:10 scale models for the offshore
sector. Further key research topics
include grid-supporting strategies for wind
turbines and generator diagnosis systems,
e.g. early fault detection or the origins of
bearing currents.
Short-circuit-proof, arcresistant
and shatterproof
New VEM cable terminal passes testing
A new cable terminal for electric machines
has been developed, manufactured and tested
successfully by VEM. The test institute
IPH Berlin, too, has confirmed that the new
solution is not only short-circuit-proof, but
also arc-resistant and shatterproof. Designed
for a rated voltage of 11 kV and a nominal
current of 400 A, it complements the cable
terminal with enhanced short-circuit strength
for 11 kV and 1600 A which VEM already
presented in 2013.
The benefits of the new terminal: It further
raises the safety of machines in operation,
and reduces the risk of accident or damage
to the machine in case of a supply network
fault. In this way, VEM is now able to satisfy
customer demands for increased short-circuit
strength and arc resistance at the cable
terminal for smaller machines with outputs
from 315 kW. That is especially relevant, for
example, with regard to the use of machines
with lower outputs in power generating
plants.

Getting to know each other,
exchanging of experiences and
discussion of the latest technical
developments – those were
the aims of a VEM service conference
at the end of February
2016. Some 20 sales partners
from Germany, Austria and
Switzerland attended the twoday
meeting in Dresden.
Given that VEM reorganised its
network of contract partners in
2015, a team get-together was
a point high on the agenda for
all concerned. It provided a
framework for introductions,
and enabled VEM to present
the offers with which it supports
the work of its partner
companies both online and locally
in their respective regions.
The participants also learned a
great deal about the individual
VEM locations; the visit naturally
included an extended tour
of the Sachsenwerk factory.
It is planned to repeat such
conferences on an annual
basis. The focus will then be
placed above all on technical
issues and developments.

New responsibilities for Dr. Henri Arnold
Dr. Henri Arnold is married and the father of
two school-age children. In his spare time, he
plays volleyball and football on a regular basis,
is a member of the volunteer fire service,
and enjoys restoring old motorcycles.
With effect from 1 st March 2016, Dr.
Henri Arnold (39) has taken up the post
of technical manager for electric drive
systems at VEM transresch, allowing
longstanding predecessor Wolfgang
Schramm to enter his well-earned
retirement.
Henri Arnold studied mechanical engineering
at the Freiberg University of
Technology and joined VEM in Dresden
after obtaining a doctorate from the
department of electric machines in
2007. He subsequently worked in the
office responsible for electromagnetic
calculations at Sachsenwerk for nine
years. In his new function, the first task
for Henri Arnold will be to manage
the relocation of VEM transresch from
Berlin to Dresden. A further focus of
his work will be to promote customer
awareness for VEM as a full-range
supplier of complete drive systems. As
a graduate engineer with a good standing
in the academic world, he also
plans to strengthen VEM‘s scientific
lead through even closer contact to the
universities, and in this way to remain
one step ahead of the market.

Closer contact
VEM sales managers join longstanding

Teheran
A symposium organised specifically for
VEM by the Iranian Ministry of Water
attracted some 500 participants to
Teheran in January 2016. Sales management
representatives from VEM joined
longstanding Iranian partner VEM Pars
to present the whole product portfolio
of the VEM group, for example high and
low-voltage machines, drive systems,
and also various foundry products from
Keulahütte Krauschwitz. The attendees,
among them government representatives,
planners, engineers and plant
operators, displayed considerable
interest. That was probably also reward
for the fact that VEM had maintained
a presence and continued to supply
drive solutions even during the difficult
years. The good contacts stem back to
the pioneering work of Jürgen Sander,
the former managing director of VEM
motors.
The business relationship with Iranian
partner VEM Pars was founded in 1994.
The company‘s activities to date have
concentrated on low-voltage motors,
sales and local manufacturing.
VEM Dresden has been successful in the
country with practically the whole spectrum
of large machine components for
the cement, oil, gas and steel industries.
To better familiarise themselves with the
whole VEM product portfolio, Pars staff
visited VEM in Dresden and Wernigerode
for a three-week course of training in
March. Specialists from VEM have also
been working in the local office in Teheran
since the beginning of 2016.

New turning centre shortens
manufacturing times
Valves, hydrants and threaded fittings can now be machined at the
highest technical level – with stabilised workpiece throughput.
At Keulahütte, the turned parts
which are required for valves,
hydrants and threaded fittings are
manufactured in a CNC cell comprising
three individual machines.
One of these turning machines,
the DFS 2/4 for chuck and centre
clamping, has been in use since
1993. Investment in a replacement
for this technically outdated machine
was thus becoming imperative.
The ideal replacement, and
one which meets all aspirations to
manufacturing at the highest technical
level, is a DOOSAN PUMA GT
2600M turning centre.
Factors which sealed this investment
decision were the enormous
performance capabilities of the machine,
the reliability of the manufacturer,
the availability of competent
local support, and the fact that the
machine controls are comparable to
those of the existing CNC systems.
The new turning centre has shortened
the previous manufacturing
times by 20 per cent thanks to its
faster tool changing and increased
rapid traverse rates. All workpieces
The new turning centre and a view into its inner workings (above left)
which were formerly machined on the DFS 2/4 have been
switched to the DOOSAN PUMA GT 2600M. A further positive
effect of this modernisation is realisation of an urgently necessary
cost reduction for the manufacturing and machining of
fittings and valve and hydrant parts at Keulahütte, as response
to the negative developments in current market price levels.

Keulahütte at Ecwatech
2016 in Moscow
One important date on this year‘s international trade
fair calendar is Ecwatech 2016, which will be taking
place in Moscow from 26 th to 28 th April. It goes without
saying that Keulahütte is among the exhibitors
represented at the fair.
Ecwatech is for Keulahütte the most important forum
for water supply technologies and management in
the whole Russian-speaking region. This branch fair
presents a broad spectrum of products and solutions
relating to the use, restoration and conservation of
water resources, water and wastewater treatment
and water supplies, including the construction and
maintenance of piping systems. The opportunity to
present the Keulahütte range of butterfly and gate
valves, and above all its GOST-approved hydrants, is
expected to attract further customers from the region.
Present at the most important
branch meeting in Munich
in particular, has contributed to the
sustained underutilisation of capacities
in the iron and steel foundries.
Under these circumstances, the
foundries find themselves confronted
with customer demands for massive
price reductions. The stagnating purchasing
prices for raw iron and steel
scrap already serve as the principal
argument for necessary adjustments.
But this view completely disregards
a whole host of other significant cost
factors.
The greatest source of risk for the
so-called “hot industries” remains the
problem of energy prices. The real
issue is no longer the price for the
actual electricity. In the meantime, it
is the payments for grid use and a
never-ending variety of new state levies
which make cost calculations an
unpredictable undertaking. While the
actual electricity costs still accounted
for 64 per cent of the overall price
of energy in 2007, this share had
02 March 2016 | VEM Impulse
on energy consumers. In addition to
levies defined in the Renewable Energy
Act (EEG), the Combined Heat
and Power Act (KWKG) and the Grid
Charge Compensation Ordinance
(StromNEV), the latest addition to the
list is an offshore liability levy, which is
intended to spread the compensation
claims of wind farm operators
whose offshore installations cannot
be connected in due time by the
corresponding grid operators. An
energy tax of presently 2.05 ct/kWh
and – last but not least – valueadded
tax on all the aforementioned
price components round off the truly
chaotic picture.
As typically smaller representatives
of the hot industries, the foundries
are following such developments
with great concern, also because
various other cost elements are being
distorted out of all proportion by state
and regional economic regulation.
To be continued …
The world‘s leading trade fair for the water supply,
wastewater, disposal and raw materials branch, IFAT
2016, will be opening its doors in Munich from 30 th
May to 3 rd June. Here, too, Keulahütte will be among
the exhibitors. A review of the last IFAT fair in 2014
shows that all previous records were broken. Over
135,000 visitors from 168 countries flocked to Munich
to catch up with the latest branch trends. The constantly
increasing number of exhibitors also confirms
the prime importance of the fair. Keulahütte will be
using the fair to demonstrate its competence at all
stages of the manufacturing and supply chain, from
initial casting to a ready-to-install final product.
Given the high proportion of international visitors in
Munich, IFAT is seen as a great opportunity to gain
new customers beyond the German market.

Company visit
First-hand career peparation
Trainees from LWG Lausitzer Wasser visit Keulahütte
Career preparation of a
very special kind awaited
fourth-year trainees from the
transregional training centre
of water and wastewater utility
company LWG Lausitzer
Wasser GmbH & Co. KG on
19 th January 2016. A few days
before the end of their training,
they visited Keulahütte
in Krauschwitz (Saxony).
Keulahütte produces above
all fittings, butterfly and gate
valves, hydrants and specially
designed custom castings.
Particular importance is
attached to product quality
and sustainability. With
approximately 300 employees,
Keulahütte is one of the most
important employers in the
Lusatian region, and furthermore
a longstanding partner
and supplier of the water and
wastewater branch.
The purpose of the excursion
was to acquaint the future
plant mechanics with the
manufacturing and special
features of those products
which will soon be standing
at the focus of their work. The
visit began with a detailed and
very informative presentation
on commercial processes relating
to sales, marketing and
accounting, and an introduction
to the various production
processes and workpieces.
This was followed by a tour of
the production centre.
The 19-hectare site accommodates
all the relevant
production and machining
processes. There are only a
few plastic and metal parts
which must be purchased
externally, but even they are
A whole new experience: Future plant mechanics during their tour of the production centre at Keulahütte
obtained from regional suppliers wherever possible.
“In our eyes, it is an important contribution
to the quality of our products and the continued
stability of the local economy that we cooperate
primarily with regional partners,” says sales representative
Sigmund Pionty. “We can thus state
proudly that our products are in every respect
‘Quality made in Germany’.”
New experiences gained
The tour organised for the trainees and their
instructors included the pattern workshop, the
melting furnaces, the mouldmaking department
and, of course, the casting process
itself. The visitors were especially impressed
by this striking process, where liquid iron at
a temperature of around 1400 °C is poured
into a specially formed sand mould. In later
everyday use, the various products are exposed
not only to environmental influences,
but also to considerable climatic, chemical
and mechanical stresses, and must thus be
prepared for all coming eventualities. Not least
for this reason, Keulahütte possesses its own
test laboratory for quality testing and assurance.
Along the way, the future specialists
had ample opportunity to ask all manner of
questions on test methods, material compositions
and the special demands applicable in
the individual sales departments, for example
differences between the German and the
European markets.
Another interesting stop on the tour addressed
the mechanical machining of raw castings on
a range of drilling machines, turning lathes and
CNC milling centres, as well as the GSK-compliant
powder coating of fittings, valves and hydrant
parts. Much of the machining is done on
ultramodern computer-assisted robot systems,
though there are still numerous tasks which
require direct manual intervention. The tour of
the production centre ended in the assembly
department and the workshops responsible for
function testing and the tightness of all seals.
All in all, the trainees were treated to an well
organised and structured visit, with a great deal
of valuable information on a topic which was for
most a whole new experience. The feedback
from the visitors was correspondingly positive.
They appreciated, in particular, the closer
insights into the functioning of relevant products
in the run-up to their final practical examinations
in February. Furthermore, they were able to gain
a first-hand impression of the high quality standards
which apply at the foundry stage, and the
special conditions under which Keulahütte is
active for the water industry and other
branches. Paul Zisowsky, LWG trainee

Water supplies
Traditionally good cooperation with regional utility
ZWAR Rügen has been using
Keulahütte products for
many years
The regional utility association
for water supplies and wastewater
treatment on the Baltic
island of Rügen (ZWAR) is today
an economically successfully
enterprise with firm roots in the
region. It supplies drinking water
to towns and villages throughout
the islands of Rügen, Ummanz
and Hiddensee, and also provides
for treatment and disposal
of their wastewater. A total of
41 communities are members of
ZWAR. Some 4.7 million cubic
metres of groundwater are processed
into high-quality drinking
water in 29 waterworks, and
39 fully biological treatment
plants enable five million cubic
metres of wastewater to be purified
and returned to the natural
water cycle. This purification
capacity represents a major
contribution to the water quality
along the island‘s beaches. The
drinking water and wastewater
networks maintained by ZWAR
each measure 850 kilometres.
Since the founding of the
regional association on 3 rd June
1992, over 250 million has been
invested in plant erection and reconstruction,
as well as in major
overhauls. The goal is to provide
reliable drinking water supplies
and wastewater disposal for the
70,000 local inhabitants, not to
mention the countless tourists
and a broad spectrum of industrial
and commercial consumers.
That has demanded a targeted
and systematic modernisation
programme. As further enterprises
have settled on the island,
and with further development of
the tourist infrastructures, it has
also been necessary to expand
the installations and networks
accordingly.

the components of choice for
ZWAR. Together with predominantly
regional building contractors
and specialist civil engineerelectric
drives. Further construction
projects were realised at the
port of Mukran, where oval-wedge
gate valves in sizes DN 100-300,
Keuladrant underground hydrants
in size DN 80 and an assortment
of ductile fittings from Krauschwitz
were used. In the meantime, the
use of fittings and valves with
epoxy resin powder coatings has
also gained widespread acceptance
on the island of Rügen. Visitors
who explore the sunny holiday
island with an open eye will come
across the most varied models of
overground hydrants manufactured
by Keulahütte, for example “hidden”
hydrants in the dunes by the
Cliff Hotel in Sellin.
In the future, too, the proven
Keulahütte product range will be
helping to guarantee reliable water
supplies to ZWAR customers. The
association‘s modern parts store in
Bergen plays an important role in
this connection. Over 800 different
articles are held in stock and are
ready for delivery to any the five
supply districts on the island of
Rügen at a moment‘s notice.
Fair
Exhibition at the Oldenburg Pipe Forum
Conference at the interface between
study and practice celebrated its 30th
anniversary in 2016
As in previous years, the rooms and
grounds of the Jade University of Applied
Sciences were venue for the traditional
Oldenburg Pipe Forum and its flanking
exhibition on 11 th and 12 th February 2016.
This year‘s event was already the 30 th in
the series. Compared to January 1987,
when no more than 100 participants met
in a lecture hall on the Oldenburg campus
to listen to 12 presentations on the subject
of “Plastic piping in the construction
industry”, the forum has today evolved into
a major platform for intensive exchanges
between leading branch experts. In the
meantime, the number of visitors has risen
to more than 3,000. Keulahütte has been
a regular exhibitor at the forum for over
15 years and has experienced the positive
development at first hand. Interesting presentations
and opportunities for in-depth
discussions with a broad spectrum of
branch representatives are characteristic
for the conference in Oldenburg.
