The electric power of an electric motorcycle racing car supplies electric power to the electric motor of the electric motorcycle. When it is used, its electric motor converts the electric energy of the electric power into mechanical energy, and through its transmission device or directly drives the wheel and the working device during operation, today, the electric vehicle The most widely used power source is lead-acid battery, but with the development of electric vehicle technology, lead-acid batteries are gradually replaced by other batteries due to lower specific energy, slower charging speed and shorter life. The application of new power sources is being developed, opening up broad prospects for the development of electric vehicles.
The electric motorcycle racing car is put into the role of the driving motor. In use, the electric energy of the electric power source is mainly converted into mechanical energy, and the driving is mainly through the transmission device or directly driving the wheel and the working device. DC series motors are widely used in today's electric vehicles. These motors have "soft" mechanical characteristics that closely match the driving characteristics of the car.
Due to the existence of reversing sparks, the DC motor of electric motorcycle racing will be less powerful than power, low in efficiency, and large in maintenance workload. With the development of motor technology and motor control technology, it is bound to be brushless by DC. Motor (BCDM), switched reluctance motor (SRM) and AC asynchronous motor are replaced.
The motor speed control device of the electric motorcycle racing car is set for the shifting and direction change of the electric vehicle, and its main function is to control the voltage or current of the motor, and to complete the control of the motor driving torque and the rotating direction to a certain extent.
