RDDSP56F8BLDCHS: 3-Phase BLDC Motor Control w/Hall Sensor Reference Design for 56F80X/56F8300 DSCs

Overview

This reference design describes the design of a 3-phase BLDC (Brushless DC) motor drive, which supports the NXP® 56F80X and 56F83XX Digital Signal Controllers (DSCs).

  • The speed-closed loop BLDC drive using a Hall sensor is implemented
  • The system is targeted for applications in both industrial and appliance fields (e.g. washing machines, compressors, air conditioning units, pumps or simple industrial drives required high reliability and efficiency)

Features

  • Voltage control of BLDC motor using Hall sensor
  • Targeted for 56F80X, 56F83XX, and 56F81XX Digital Signal Controllers
  • Running on 3-phase Motor Board
  • Control technique incorporates:
    • Voltage BLDC motor control with speed-closed loop
    • Current feedback loop
    • Both directions of rotation
    • Motoring mode
    • Minimal speed 500 RPM
    • Maximal speed 1000 RPM (limited by power supply)
  • Manual interface (Start/Stop switch, Up/Down push button control, LED indication)
  • FreeMASTER software control interface (motor start/stop, speed set-up)
  • FreeMASTER software monitor
