1. Motor controller for DC 12 or 24 or 48V BLDC 6 60V 400W or 3 phase brushless motor 2. Stable: Made of durable materials, ensuring the longevity and reliability of the motor controller. It is built to withstand continuous and heavy duty use. 3. Efficient motor performance: The MA, MB, and MC phase lines are directly connected to the motor, providing seamless and efficient power transmission for motor performance. 4. Multiple power supply options: The controller includes a 5V GND power supply for the motherboard (current not exceeding 30mA) and a VCC GND main power supply for the motor (external DC supply), enabling flexible power configurations. 5. Precise Speed Control: VR speed control signal input supports both the built in potentiometer speed control and an external 0 5V analog or PWM duty cycle input, allowing precise speed adjustment to meet specific requirements.
