Lenze three-phase AC motors - MEYLE - Meyer Industrie Electronic ...

Overview
General
Robust three-phase asynchronous motors are used in
almost all sectors of industry. Their extremely compact
design and high protection have already enabled them to
win over a large share of the DC drive market.
Lenze Drive Technology is able to offer complete solutions
for this area of application. In addition to asynchronous
motors, our product range also features matched frequency
inverters and numerous types of gearbox. The three-phase
AC motor with motec is a new integrated solution.
Our three-phase AC motors are particularly suitable for
inverter operation. Modern inverters switch output stages
at clock frequencies between 4 and 16 kHz, which can give
rise to high rates of voltage rise and overvoltages in the
motor windings. The windings and insulation system have
been designed specifically to ensure reliable continuous
operation.
The motors are fitted as standard with temperature sensors
which can be used for temperature monitoring and are
set to motor thermal class F (155°C).
The motors are supplied as standard with IP54 protection
although the drives can also be supplied with IP55 protection
as an option.
Lenze has built an extremely high-quality and cost-effective
system. Two different non-drive end shaft ends along
with a universal non-drive end bearing cover and the
modular design enable various feedback systems and
brakes to be added as options.
Resolvers or incremental encoders as well as variants
featuring the well-known BFK458 spring-operated brakes
can also be added.
This system is also characterised by a universal terminal
box. All possible connections can be housed in a single
compact application terminal box. On drives with built-in
inverters, the connections are wired in the inverter.
A well-designed concept and complete solution for users
from a single supplier.
