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. The chip integrates a dedicated non-inductive motor driver circuit, offering a simple peripheral design, complete functionality, compact size, easy debugging, high driving efficiency, flexible application, and wide compatibility. The SNR8503M features 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. Users can perform secondary development based on this firmware to accelerate product integration. Features: - Drive module dimensions: 78x57mm, board thickness: 1.6mm - Operating voltage range: 6-80V - Built-in reverse polarity protection prevents damage from incorrect power connection - Module is unenclosed by default. For drive currents under 5A, no forced cooling is requiredensure normal ventilation. Forced heat dissipation is necessary for currents exceeding 5A - Onboard LED indicators display standby, operation, and error statuses - Integrated potentiometer (0.55V) with PWM speed control interface (frequency 120kHz, duty cycle 10100%) - FG speed feedback interface; RPM = FG frequency (Hz) 60 / number of poles - CW/CCW direction control interface: floating for clockwise (CW), grounded for counterclockwise (CCW) rotation - UART serial interface allows module control via serial communication protocol - Programming interface provided for firmware updates Specifications: - Operating voltage: 680V - Maximum current: rated 20A, peak 50A - Maximum power: 1600W - Overcurrent protection: included - Product dimensions: 78mm x 57mm x 20mm Functional Layers: - Motor drive base - Non-inductive startup layer - Back EMF commutation layer - Phase compensation algorithm - Velocity closed-loop PID control - Current limiting PID control - Downwind start-up algorithm Applications: Pumps, medical devices, compressors, fans, electric screwdrivers, electric curtains, automatic doors, hydraulic oil pumps, air pumps, refrigerator brushless DC compressors, lawn mowers, sprayers, underwater thrusters, and similar equipment.
