Motor speed control device
The motor speed control device is provided for shifting and direction change of the electric vehicle, and functions to control the voltage or current of the motor to complete the control of the driving torque and the rotation direction of the motor.
In previous electric vehicles, the speed regulation of the DC motor was achieved by using a series resistor or changing the number of turns of the motor field coil. Because the speed regulation is stepped, and the additional energy consumption or the structure of the motor is complicated, it is rarely used today. Today's electric vehicles are widely used in thyristor chopper speed regulation. By uniformly changing the terminal voltage of the motor and controlling the current of the motor, the stepless speed regulation of the motor is realized. In the continuous development of electronic power technology, it has gradually been replaced by other power transistors (into GTO, MOSFET, BTR and IGBT, etc.) chopper speed control devices. From the perspective of the development of technology, with the application of new drive motors, the application of the speed control of electric vehicles to the application of DC inverter technology will become an inevitable trend.
