Drive and load machines for testing drive trains

The drive and load machines of the ECODyn G series are intended for testing powertrains in the electric mobility sector and in transmission development, which they cover optimally with their high torques. The max speed is up to 3500 rpm.

The basic scope of the ECODyn G series for powertrain modules always consists of:

  • Multiple drive systems from asynchronous machines including torque measuring flange and speed sensor,
  • an inverter system with input rectifier and inverter
  • each projected as a finished module
