REFMOT201 - Reference Design
AC supply, Sensor-less, Three Phase Brushless DC motor drive
An evaluation board that enables direct input of AC power to a BLDC motor unit by installing an ACDC converter circuit in the drive circuit for a three phase DC brushless motor (hereafter BLDC motor) . This is an evaluation board that enables direct input of AC power to the BLDC motor unit. Targeting small motors up to 10W class, this evaluation board has a three phase motor driver + ACDC converter (12V output) on one small board. It is possible to drive a three phase BLDC motor with an AC motor interface.
- Input AC power supply voltage 90to264V
- Motor DC voltage 10.4to13.2V
- Output current 1.0A(max)
- Sensorless 12V three phase brushless DC motor drive
- Motor driver: Motor driver LSI
- Sine wave commutation PWM drive
- Speed control by DC/PWM input
- Rotation direction setting
- Rotation speed pulse signal output (FG, 1/2FG)
