Tackling key challenges of e-motors

OEMs are striving to increase the efficiency of the e-motor/inverter by tackling many challenges:

  • Deliver a high-efficiency all across the eMotor torque/speed operating range
  • Deliver a wider operating range with higher torque and speed range
  • Deliver more power with less rare earth material and with less costs
  • Reduce the transmission / speed reducer needs and costs
  • Rapid fault detection and response time assuring highest levels of safety for the consumer
