TIDA-00112
5V, 3-Phase, Sensorless Motor System With Variable Speed Control
TIDA-00112
Overview
This reference design provides a simple way to spin and control a 5V, 3-phase, BLDC fan motor with minimum development time and overhead. It utilizes the DRV10866, a sensorless BLDC motor driver, for the power stage and a TLC555 timer to provide a variable duty cycle PWM signal for speed control. The DRV10866 uses a 150 degree sensorless BEMF control scheme that takes away the need for external sensors on the motor.
Features
- Low Voltage, 150 Degree BEMF Sensorless Motor Control
- Speed Control Through Onboard Potentiometer
- Compact Board Size (Can Fit Onto Fan Itself)
- Can Be Powered From Micro-USB Cable, No Power Supply Required
- Low Development Overhead, Design is Orderable and Tested
- No Firmware Required, No MCU Required
