Speed control device of green energy electric scooter
Jul 11, 2018

The motor speed control device of the green energy electric scooter is set for the shifting and direction change of the electric vehicle. The main function of the electric vehicle is to control the voltage and current of the motor, and to effectively complete the driving torque of the motor. Control of the direction of rotation.


The speed regulation of the DC motor of the green energy electric scooter is realized by using its series resistance 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. Today's electric vehicles are widely used in thyristor chopper speed regulation, which achieves stepless speed regulation of the motor by uniformly changing the terminal voltage of the motor and controlling the current of the motor.


From the perspective of the development of technology, the green energy electric scooter, with the application of the new drive motor, the application of the speed control of the vehicle to the application of the DC inverter technology will become an inevitable trend to some extent, in the rotation of the drive motor. In the change control, the DC motor relies on the contactor to change the direction of the current of the armature or the magnetic field, thereby realizing the direction change of the motor, which makes the hole-ha circuit complicated and reliable.
