RD3PHBLDCSC: 3-Phase BLDC Sensorless Control with MQX™ RTOS Reference Design using Kinetis K60

Overview

This NXP® reference design is a speed closed-loop BLDC drive using a sensorless technique that serves as an example of a BLDC motor control design using an NXP K60 MCU.

  • Simple and easy to understand control approach to BLDC, using MQX in a time-critical application.
  • Contains two versions of the application software, one with the MQX RTOS, and the other bare-metal
  • The MQX version contains a web server to demonstrate the benefits of an MQX-based solution
  • Both use the same source code for motor control

Features

  • BLDC motor control using the BEMF integration method for position determination
  • Targeted for the TWR-K60N512 controller board
  • Speed closed-loop with speed measurement
  • Adjustable speed ramp
  • Motor mode in both directions of rotation
  • Minimum speed of 400 rpm
  • Maximum speed of 4000 rpm
  • Tested up to 30 rpm with a one-pole pair motor
  • Overvoltage, Undervoltage and overcurrent fault protection
  • FreeMASTER control interface
  • Control via a web server
