Company product advantages

Our controller development has gone through many times of technical innovation, our company launched a new generation of intelligent vector controller to the market response is very good, efficient, low noise, low damage rate is the characteristics of this controller.

The working principle and advantage of intelligent vector controller

Vector control time tracking motor Angle (Q axis and D axis), no matter at what speed at what time the output of the maximum torque, especially when uphill, riding feeling is obviously strong.

The vector controlled phase current is closed loop, and the string waves are open loops.The advantage of the closed loop is that the current will not overshoot, thus protecting the MOS tube and greatly reducing the damage rate of the controller.

Due to the under-control moment to play the maximum torque output and phase current closed loop, so the impact on the motor minimum, reduce the motor heat, protect hall and magnetic steel, extend the life of the motor, reduce the motor damage rate.
