1. Motor controller for DC 12/24/48V-BLDC 6-60V 400W/3 phase brushless motor 2. Robust and durable: Built with high-quality materials for durability and long service life; designed for continuous, heavy use. 3. Efficient motor performance: MA MB MC phase lines connect directly to the motor windings to provide seamless power transmission and optimized performance. 4. Flexible power options: The controller provides a 5V GND supply for the motherboard (current not exceeding 30 mA) and a VCC GND main power supply for the motor (external DC supply), enabling flexible power configurations. 5. Precise speed control: VR input supports both built-in potentiometer speed control and an external 0-5V analog or PWM control signal for precise speed adjustment. 6. Applications: Suitable for electric bikes, scooters, and other 6-60V systems up to 400W; ideal for DIY robotics, CNC gantries, or small EV projects requiring accurate 3-phase BLDC control.
