Introduction

This reference design demonstates a motor control solution for 3-phase permanent magnet synchronous (PMSM) motor, using ATxmega16D4 microcontroller. This reference design features a PC configuration utility for configuring and tuning sensorless field oriented control (FOC) parameters.

Key Features

  • Sensorless field oriented control (FOC) algorithm implemented in ATxmega16D4
  • 3-phase permanent magnet synchronous (PMSM) motor application
  • 3-phase half-bridge gate drive circuitry with N-MOSFETs as lower switches and P-MOSFETs as upper switches
  • Single shunt current reconstruction
  • PC based configuration utility and tuning guidelines
