HDSC Motor Control Development Guide
Introduction
This guide covers motor control application development using HDSC HC32F series microcontrollers with a focus on BLDC and PMSM motor control.
Motor Control Basics
BLDC Motor Control
Brushless DC (BLDC) motors use electronic commutation:
- Six-step trapezoidal commutation
- Hall sensor or sensorless control
- PWM speed regulation
PMSM Motor Control
Permanent Magnet Synchronous Motors (PMSM) use:
- Field Oriented Control (FOC)
- Sinusoidal current drive
- Higher efficiency than BLDC
