Mgm Variable Speed Motors

Built-in inverter motors consist of three-phase asynchronous electric motors with an integrated frequency inverter. The power range is between 0,37 kW and 15,0 kW while the motor frame is from 71 up to 160.
The unit is composed of a high-efficiency 3-phase asynchronous electric motor and a compact frequency inverter placed at the non-drive motor end.

The basic construction is closed, fan cooled and IP 55 enclosure duty. A built-in inverter motor is able to properly run also under heavy overload conditions thanks to a high thermal reserve; the insulating materials are class F. The frame is made of aluminum alloy up to 132 frame size and of cast iron for above sizes.

Mgm brake motors

MGM brake motors are asynchronous three-phase totally enclosed fan cooled motors:

  • MX Series is the standard series of high-efficiency motors
  • BA Series: AC/DC brake motor series (the engineered series)
  • BM Series: DC brake motor series (Motor plus a DC brake)
  • SMI Series is the built-in inverter motor series

MGM brake motors are designed and assembled as real brake motors. The perfect engineering and assembling combined with a strong and safe brake, make these motors very reliable.

Feet are integrated in the frame (they are not attached to the frame) as standard on the IM B3 foot mounted motors. This feature is very important on those applications where the stress during start/stop requires a very sturdy motor.

SMX and SMI series are provided with IP55 enclosure rating (IP56 or IP66 available on request). BA and BM series are provided with IP 54 enclosure rating (IP55, IP56 or IP66 available on request). Winding Insulation class is F (Class H on request).

All MGM motors are designed for inverter duty. On request it is possible to supply the motor with the encoder fitted on the ND shaft end or to have the ND shaft end ready to fit an encoder (E series).

MGM also manufactures Totally Enclosed Not Ventilated motors (S series).
