Controller PWM High Power 1600W Motor DC 6-80V BLDC Three Phase DC Brushless Motor Control Driver Board Motor Regulator No Hall This product is a non-inductive BLDC motor driver module developed using the SNR8503M drive chip, which integrates a specialized non-inductive motor driver circuit. It features a simple peripheral design, complete functionality, compact size, easy debugging, high driving efficiency, flexible application, and wide compatibility. The SNR8503M utilizes a 32-bit core MCU, making development and simulation debugging convenient. To help users quickly drive non-inductive BLDC motors, the core software algorithm has been pre-programmed, allowing users to perform secondary development based on this foundation for rapid product deployment. Features: - Drive module dimensions: 78x57mm, board thickness: 1.6mm - Operating voltage: 6-80V - Supports reverse polarity protection; the module will not be damaged if power lines are connected in reverse - Default configuration is bare board. For motor operation below 5A, no forced cooling is requiredensure normal ventilation. Forced heat dissipation is required when drive current exceeds 5A - Onboard LED indicators for standby, operating, and error status - Built-in potentiometer (0.55V), PWM speed control interface (frequency 120kHz), duty cycle range 10100% - FG speed feedback interface; RPM calculation: FG frequency (Hz) 60 / number of poles - CW/CCW direction control interface: floating for clockwise (CW), shorted to GND for counterclockwise (CCW) - UART serial interface for module control via serial protocol - Programming interface for firmware updates Specifications: - Operating voltage: 680V - Maximum current: rated 20A, peak 50A - Maximum power: 1600W - Overcurrent protection: yes - Product dimensions: 78mm x 57mm x 20mm Functional Layers: - Motor drive base - Non-inductive startup layer - Back EMF commutation layer - Phase compensation algorithm - Speed closed-loop PID algorithm - Current limiting PID algorithm - Downwind start-up algorithm Applications: Pumps, medical equipment, compressors, fans, electric screwdrivers, electric curtains, automatic doors, hydraulic oil pumps, air pumps, refrigerator brushless DC compressors, lawn mowers, sprayers, underwater thrusters, and more.
