DC 6.5-50V 380W BLDC 3 Phase Brushless Motor Driver
Designed for BLDC brushless DC motors. The controller allows you to adjust the rotation speed and change the direction of rotation of the motor. It has a wide supply voltage range from 6 to 50V DC, the maximum output power of the module is 380W. The controller supports motors without Hall sensors.
Speed control is done by adjusting the supply voltage (potentiometer adjustment) or by adjusting the PWM filler 0 -5V. The module has a built-in potentiometer to adjust the speed, but we can connect an external potentiometer by shorting the pins on the jumper on the module.

Interface Description
- U V W phase wire output connects to the motor
- 5V GND motherboard, Comes with power supply (current does not exceed 300MA)
- VCC GND Motor main power supply (external DC power supply)
- SC speed pulse signal output
- DIR forward and reverse control (can lead to external switch)
- BRAKE brake control (external switch can be wired)
- 0-5V PWM speed control signal input (onboard potentiometer can be used to adjust the speed or an external 0-5V analog quantity PWM duty cycle signal input can be used to adjust the speed with the jumper)
WARNINGS
- There is no fuse in the power supply circuit on the main board. It is recommended that you add it yourself. The positive and negative poles of reverse connection of the power supply will cause damage to some chips on the board (even for 2 seconds).
- During normal operation, there is sampling overcurrent protection at the motor output. Because the module power and current are very large, please do not short-circuit artificially when the module does not work normally. When short circuit has the possibility of burning the line, please use small current and low voltage test for Secondary wiring testing. After completion, pass high current and high voltage. Since it is a bare panel module, pay attention to the cable head insulation.
