High-Voltage Sensorless 3-Phase EC BLDC Drive Module

High-Voltage Sensorless 3-Phase EC BLDC Drive Module

Product Description:

This EC drive module accepts 220V AC input, which is electronically rectified inside the module into high-voltage DC (310VDC) to directly drive three-phase BLDC motors. Equipped with a high-performance MCU and self-developed FOC sine-wave drive control algorithm software, it integrates multiple functions including soft start, stall protection with auto-restart, overcurrent protection, current limiting, closed-loop speed control and closed-loop power control. It supports isolated PWM/VSP speed regulation and FG/RD signal output. Customized functions are available upon request.
