MOVIGEAR® DRIVE SYSTEM
is ideal for hygiene and energy-saving in the
food and beverage industry
19 September 2017: MOVIGEAR® drive systems are particularly suited
for the food and beverage industry, with its dual demands of high
hygiene levels and energy saving, combined with the need to limit
any downtime. SEW-EURODRIVE South Africa recently supplied a
total of 65 MOVIGEAR® units to a major abattoir, representing one of
the largest projects of its kind it has supplied to date.
The units for the abattoir project are being assembled locally at the
SEW-EURODRIVE Cape Town manufacturing facility, which means fast
and reliable delivery, in addition to quick service back-up and repairs
if need be. The partial delivery allows for the project to flow smoothly,
without the MOVIGEAR® units having to be in storage too long.
“The main requirement was that we adhere to the strict delivery
timetable on the project, while the main technical challenge
was to select the correct unit that could be integrated with the
customer’s current choice of PLC,” SEW-EURODRIVE South Africa
Sales Engineer Sean Tibbott elaborates. This is of particular
importance, as the MOVIGEAR® units comprise different
communications topologies, namely DBC, DSC, DAC, or SNI, which
allows for effortless integration with existing PLC programs.
“The main contributing factor in SEW-EURODRIVE South Africa
securing this project was that we had the correct product that
suited the customer’s specific requirements,” Regional Sales
Manager Clive O’Reilly explains. Customer benefits of the
MOVIGEAR® units are ease of installation, combined with ease of
communication between the various units.
The MOVIGEAR® units reduce installation and start-up efforts
and costs, as well as minimising energy and operational costs.
In addition, the design complies with all of the necessary
requirements in terms of hygiene-sensitive areas in the food and
beverage industry.
The MOVIGEAR® unit is highly integrated, comprising three
different sections, namely an electronic inverter, which is
connected to the servo motor and, in turn, connected to the
gearbox section. “It is essentially a mechatronic drive system,”
Tibbott highlights. The integration allows for minimal electrical
and mechanical losses through direct contact or connection
between the drive components. This low-noise drive system
makes for reduced noise levels, meaning it is ideal for areas where
workers are present.
The MOVIGEAR® units are available in three different torque
variants, namely 200 Nm, 400 Nm, and an extended torque version
(representing a 16% increase over the largest torque output).
Standard features include IP65 and IP69K rating, which makes
them ideal for the demanding requirements of the food and
beverage industry. “Another key differentiator is that more than 20
different ratios are available, allowing for maximum flexibility in
selecting application speeds,” Tibbott points out.
