Overview

This reference design describes the design of a 3-phase BLDC (Brushless DC) motor drive, which supports the NXP® 56F801X Digital Signal Controllers (DSCs).

• The speed-closed loop and torque control 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 56F801X Digital Signal Controllers
• Running on 3-phase Motor Board
• Control technique incorporates:
  • Voltage BLDC motor control with speed-closed loop
  • Current feedback loop
• Manual interface
• DCBus undervoltage fault protection
