24-V, 50-W BLDC Motor Sinusoidal Drive Reference Design for Air Purifier Fans

TIDA-00656

Design files

Overview

The TIDA-00656 reference design is a cost-effective, small form-factor (SFF),  three-phase sinusoidal motor drive for brushless DC (BLDC) motor up to a power of 50 W at 24 V. The board accepts 24 V at the input and provides three motor outputs to drive the BLDC motor sinusoidally. By using a microcontroller (MCU), in this case the MSP430G2303, the speed loop is closed externally after accepting the speed command over IR (infra-red) sensor.

Features
  • 50-W, 24-V Drive Capable of Driving Brushless DC (BLDC) Motors With Sinusoidal Commutation
  • MSP430G2303 Functions to Accept the IR input and Close External Speed Loop
  • DRV10983 Uses Proprietary Sensorless Control Scheme to Provide Continuous Sinusoidal Drive, Significantly Reducing Pure Tone Acoustics That Typically Occur as a Result of Commutation
  • Integrated Buck/ Linear Regulator to Efficiently Step Down Supply Voltage to 3.3 V for Powering Both Internal and External Circuits (TI MSP430™ MCU in This Design)
  • Hardware design tested at 50W with good thermal performance
  • This Design is a Tested, Ready to Use Hardware and Software Platform for Driving 12V/24V, <50W BLDC Motors
