Electric Traction Drive System

Zytek have developed a high power, compact, electric drive package comprising;

  • 3 phase permanent magnet synchronous machine (PMSM)
  • Control electronics
  • Integrated concentric gearbox (optional)

The powertrain is intended for use in electric and hybrid vehicles using a vehicle controller, high voltage battery and other supplementary systems supplied by the customer.

Inverter communication is via Flexray, optional CAN system under development and integration. The twin motor concept has been developed under ISO26262 to safety level ASIL-D.
