1.Motor controller for DC 12/24/48V BLDC 6 60V 400W/3 phase brushless motor 2.Robust and : Made of materials, durability and longevity of the motor control. It is built to withstand continuous and heavy use. 3.Efficient motor performance: the MA MB MC phase line is directly connected to the motor and provides seamless and efficient power transmission for optimal engine performance. 4.Multiple power supply options: The controller comes with a 5V GND power supply for the motherboard (current no more than 30mA) and a VCC GND main power supply for the motor (external DC supply). This allows 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 switch on cycle input, which allows precise speed adjustment according to specific needs.
