Permanent Magnet Electric Motors

The MOTEG MMA motor series consists of water- and air-cooled permanent magnet synchronous motors (PMSM), which have been developed for the use in mobile applications. During the design phase of these motors, special emphasis was put on optimizing the relationship between power density, efficiency, noise and costs. The aim was to develop a high efficiency motor, that can be used where only limited build in space is available, while at the same having a low vibration- and noise-profile.

Compared with standard norm motors, the MMA-Series is up to 6-times lighter, the motor size was downsized by up to 4 and the length was reduced by close to 75 %.

To cover the complete range of mobile applications, the MMA-Series is available in both high- and low-voltage variants. This includes 24 V, 48 V, 230 V (325 VDC-Link) and 400 V (565 VDC-Link) motors.

  • Compact size
  • High power density and efficiency
  • Low noise and vibration
  • Supply Voltage DC*: 24 V – 800 V
  • Supply Voltage AC*: 230 V and 400 V
  • Customized flange and shaft options

*The MMA-Series motors must be used in combination with an inverter
