• Compact construction through integrated power electronics 
  • Speed, torque and voltage control via CAN bus
  • Especially developed for use in mobile machines  
  • With integrated EMC concept
  • Easy system integration

The drives and generators of the powerMELA family are permanently excited synchronous machines which are available in a compact design due to the integrated power electronics. The oil cooling used, which is designed for high continuous performance, makes them ideal for use in mobile machines as generators or main and auxiliary drives. 
The machines have been designed for four-quadrant operation and permit the recovery of brake energy in battery-electric system architectures. The machines can be operated at setpoint values via CAN bus for the control of torque, voltage and speed. 
The combination of power electronics and the motor achieves high degrees of efficiency up to 95 % with continuous outputs of 80 kW and 140 kW.
In order to increase the power, two or more of the powerMELA electric machines can be combined using a summation gearbox. In this way, drives for larger commercial vehicles can also be realized. These drive packages can include sensors and control units with connections to the J1939 environment, and can be easily integrated into existing systems.
