Motor Control for electric vehicles

C2000 MCUs enable advanced technology for EV propulsion, power steering and auxiliary motors. System integration and software solutions reduce evaluation and development time.

InstaSPIN™ software provides expertise to enable rapid evaluation and development of three phase motor solutions without large engineering investments.



Traction or Propulsion Motors

TMS320F2812, Delfino™ TMS320F28335, TMS320F28377D, TMS320F28377S and Piccolo™ TMS320F28075 MCUs are widely used in high powered EV inverter traction systems, typically using resolvers or absolute encoders. InstaSPIN software enabled Piccolo TMS320F28027F, TMS320F28054M MCUs and TMS320F28069M are used for many lower voltage EV inverter propulsion systems, typically using hall sensors, incremental encoders or sensorless techniques.
