  • Indirect Field Orientation (IFO) pulse modulation maximizes torque and efficiency
  • CANBUS communication with other EV components
  • Curtis Vehicle Control Language (VCL) enables developers to write custom control software. Also, the controller features analog and digital I/O pins allowing the controller to perform whatever functions you want to program.
  • Dual drive functionality - use the controller with two motors if desired!
  • Curtis Auto-Tune lets the controller automatically adopt to any AC motor
  • Works from 0-300Hz stator frequencies (0-18000 motor RPMs) so it is suitable even in EVs without a transmission, so in a direct drive configuration it will not limit the car's speed.

  • Customer upgradeable software
  • Integrated battery state of charge measurement and hour meter
  • User selectable vehicle operation profiles
  • A special Curtis tool or Windows PC can be used to program the controller and view diagnostic information.
