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 an encoder 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 Encoder 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
