MMA Electricmotor series

Our aim was to develop a high-power electric motor for utility vehicles which is ultra-light and small, highly efficient, low-noise, but also cost-effective.

The idea behind it was to use the motor for vehicles driving in very small spaces, with minimal loss, but also low noise and vibration.

The result:The MMA Electric Motor

MMA consists of water-cooled and air-cooled permanently excited synchronous motors (PMSM) and was developed especially for mobile applications. In the development of this motor series, the emphasis was placed on determining the optimum between power density, efficiency, noise and cost.

Up to 400 VFull range for mobile applications

Compared to conventional standard motors, the MMA series is up to 6 times lighter and 4 sizes smaller, with a length reduced by up to 75%.

To cover the entire range of mobile applications, the MMA motor series is designed for different voltage levels. The MMA series includes 230 VAC (325 VDC link) and 400 VAC (565 VDC link) versions.

  • Compact design
  • High power density and efficiency
  • Low noise and vibration
  • Supply voltages DC*: 300 V - 850 V
  • Supply voltages AC*: 230 V and 400 V
  • Customer-specific solutions for flange and shaft

* The MMA motors must be operated by inverter

Our aim was to develop a high power electrical engine for utility vehicles which is ultra light, and small, maximum efficient, noise reduced and at the same time cost efficient. The idea was to be able to use the motor where it is necessary to realize a drive in a very small space with low losses and at the same time low noise and vibration.

The result is: The MMA-80 motor series. MMA consists of water-cooled and air-cooled permanently excited synchronous motors (PMSM) and was developed especially for mobile applications. During the development of this motor series, the emphasis was placed on determining the optimum between power density, efficiency, noise and cost.

  • Compact design
  • High power density and efficiency
  • Low noise and vibration
  • Supply voltages DC*: 24 V - 800 V
  • Supply voltages AC*: 230 V and 400 V
  • Customer-specific solutions for flange and shaft

* The MMA motors must be operated by inverter
