Electric motorcycle speed
Jun 27, 2018

The motor speed control device of the electric motorcycle is, to a certain extent, set for the speed change and direction change of the electric vehicle, and the main function of the electric motor is to control the voltage or current of the motor and effectively complete the driving of the motor. Torque and direction of rotation control.


The speed regulation of the DC motor of an electric motorcycle is mainly achieved by using a series resistor or changing the number of turns of its motor magnetic field coil. Due to the fact that the speed regulation is graded and additional energy consumption is generated or the structure of the motor used is complicated, it has rarely been adopted today.


The thyristor chopper speed control is widely used in today's electric motorcycles. By evenly changing the motor terminal voltage and controlling the motor current, stepless speed regulation of the motor can be achieved. In the continuous development of electronic power technology, it is gradually replaced by other power transistor (into the GTO, MOSFET, BTR and IGBT, etc.) chopper speed control device. From the perspective of the development of technology, with the application of the new drive motor, the application of the speed control of the electric vehicle to the DC inverter technology will become an inevitable trend.
