MGM brake motors are asynchronous
three-phase totally enclosed fan cooled
motors (TEFC). The motor brakes in case
of power supply failure. The braking action
is always obtained through a very quick
and precise stop and it guarantees a safe
and prompt intervention in case of an
unintentional power supply failure.
The braking action is obtained without
shaft axial sliding and it provides equal
braking torque in both directions of rota-
tion. MGM brake motors are particularly
suitable for hoisting and traverse machi-
nes, tooling machinery, automatic and
transfer machinery in textile, ceramic
and packing fields and in all those situa-
tion where precision and quickness in
braking are required.
MGM brake motors are designed and
assembled as real brake motors. The
perfect engineering and assembling com-
bined with a strong and safe brake, make
these motors very reliable.
As standard, on the IM B3 mounting (foot
mounted), feet are integrated in the frame
(they are not attached to the frame)
making the motor very sturdy. This feature
is very important on those brake motor
applications where the stress during
start/stop is very high.
The brake disc lining material is asbestos
free with high friction coefficient and very
long lasting.
The motors are provided with IP 54 en-
closure rating and insulation class F.
On request they can be provided with IP
55 or IP 56 enclosure ratings and with
class H insulation .
All MGM motors are designed for inverter
duty. On request it is possible to supply
the motor with the encoder fitted on the
second shaft end or to have the second
shaft end ready to fit an encoder. For
further information please refer to the
encoder series section.
