1-kW brushless DC motor inverter reference design


Design files


This reference design illustrates a motor inverter with MSPM0G, an Arm® Cortex®-M0+ core microcontroller. The design not only supports a sensorless Feild Orientation Control (FOC) algorithm with 1-3 shunt resistors , but also a sensored motor driving algorithm with a Hall or Quadrature Encoder Interface (QEI) sensor. The hardware and software available with this reference design are tested and ready-to-use to help accelerate development time to market.

  • Motor inverter with MSPM0
  • Supports sensored or sensorless motor control algorithm
  • Maximum Power of 1000 W at 200 V to 277 V nominal
