Drive Motors For Electric Motorcycles
Wuxi Chuang Ge Technology Co.,LTD | Updated: Jul 08, 2017

              The function of the driving motor is to convert the electrical energy of the power supply into mechanical energy, through a transmission device or a direct drive wheel and working device. Today's electric car is widely used in DC series motor, this motor has a "soft" mechanical characteristics, and the car's driving characteristics are very consistent. But DC motor because of the existence of reversing Spark, less power, lower efficiency, maintenance workload, with the development of motor technology and motor control technology, will gradually be the DC brushless motor (BCDM), switched reluctance Motor (SRM) and AC asynchronous motor to replace.Electric Motorcycle

              The motor speed control device is for the electric vehicle's speed change and the direction transformation and so on, its function is controls the electric motor the voltage or the electric current, completes the motor the driving torque and the rotation direction control.

Before the electric car, DC motor speed adjustment using a series of resistors or change the motor magnetic field coil turns to achieve. It is rarely used today because its speed is hierarchical and it generates additional energy consumption or the structure of the motor is complex. Nowadays, the wide application of the electric vehicle is the thyristor chopper speed regulation, the Stepless speed regulation of the motor is realized by changing the end voltage of the motor and controlling the current of the motor. In the continuous development of electronic power technology, it is gradually replaced by other power transistors (into GTO, MOSFET, BTR and IGBT) chopper speed control devices. From the development of technology, with the application of new driving motor, the change of speed control of electric vehicle into the application of DC inverter technology will become an inevitable trend.Electric Motorcycle

             In the Rotary transformation control of the driving motor, the DC motor relies on the contactor to change the current direction of the armature or the magnetic field, and realizes the rotor transformation of the motor, which makes the Konziha circuit complex and the reliability reduced. When the AC asynchronous motor is used to drive, the change of the motor steering can be simplified by changing the phase sequence of the three-phase current of the magnetic field. In addition, the AC motor and its frequency conversion speed control technology are used to make the braking energy recovery of electric vehicles more convenient and the control circuit simpler.Electric Motorcycle
