The electric drive and control system is composed of drive motor, power supply and motor speed control device. Other devices of electric motorcycle are basically the same as those of internal combustion engine. The composition of electric motorcycle includes: electric drive and control system, driving force transmission and other mechanical systems, working devices to complete established tasks, etc. Electric drive and control system is the core of electric vehicle, and it is also the biggest difference from internal combustion engine driven vehicle. Product classification锛?/strong Electric motorcycles are driven by electricity (battery) and are divided into electric two wheeled motorcycles and electric three wheeled motorcycles. A)Electric two wheeled motorcycle: a two wheeled motorcycle driven by electricity with a maximum design speed greater than 50km / h. B)Electric three wheeled motorcycle: a three wheeled motorcycle driven by electricity, with a maximum design speed of more than 50km / h and a curb weight of no more than 400kg. Electric mopeds are driven by electricity and are divided into electric two wheeled and three wheeled mopeds. A) Electric two wheeled moped: a two wheeled motorcycle driven by electricity and meeting one of the following conditions: ----The maximum design speed is greater than 20km / h and not greater than 50km / h; ----The curb weight of the whole vehicle is greater than 40kg and the maximum design speed is not greater than 50km / h. B)Electric three wheeled moped: a three wheeled moped driven by electricity, with a maximum design speed of no more than 50km / h and a curb weight of no more than 400kg. Phrase: Toy electric motorcycle operated motorcycle Children electric motor Powerful electric motorcycle Product composition: The power supply provides electric energy for the driving motor of the electric motorcycle. The motor converts the electric energy of the power supply into mechanical energy and directly drives the wheel and working device through the transmission device or. Nowadays, the most widely used power supply in electric vehicles is lead-acid battery. However, with the development of electric vehicle technology, lead-acid battery is gradually replaced by other batteries because of its low specific energy, slow charging speed and short service life. The application of new power supply is developing, which opens up a broad prospect for the development of electric vehicles. Drive motor: The function of the driving motor is to convert the electric energy of the power supply into mechanical energy and directly drive the wheel and working device through the transmission device or. Nowadays, DC series motor is widely used in electric vehicles. This motor has "soft" mechanical characteristics, which is very consistent with the driving characteristics of vehicles. However, due to the commutation spark, small specific power, low efficiency and heavy maintenance workload, DC motor is bound to be gradually replaced by DC brushless motor (BCDM), switched reluctance motor (SRM) and AC asynchronous motor with the development of motor technology and motor control technology. Motor speed control device: The motor speed control device is set for the speed change and direction change of electric vehicles. Its function is to control the voltage or current of the motor and complete the control of the driving torque and rotation direction of the motor. In previous electric vehicles, the speed regulation of DC motor was realized by series resistance or changing the number of turns of motor field coil. Because its speed regulation is step-by-step, and will produce additional energy consumption or use the complex structure of motor, it has been rarely used today. Nowadays, thyristor chopper speed regulation is widely used in electric vehicles. Stepless speed regulation of the motor is realized by evenly changing the terminal voltage of the motor and controlling the current of the motor. In the continuous development of electronic power technology, it is also gradually replaced by other power transistors (GTO, MOSFET, BTR, IGBT, etc.) chopper speed regulation devices. From the development of technology, with the application of new drive motor, it will become an inevitable trend that the speed regulation control of electric vehicle will be transformed into the application of DC reverse transformation technology. In the rotation direction conversion control of the driving motor, the DC motor changes the current direction of the armature or magnetic field by relying on the contactor to realize the rotation direction conversion of the motor, which makes the circuit complex and reduces the reliability. When AC asynchronous motor is used to drive, the change of motor direction only needs to change the phase sequence of three-phase current of magnetic field, which can simplify the control circuit. In addition, the use of AC motor and its frequency conversion speed control technology makes the braking energy recovery control of electric vehicles more convenient and the control circuit more simple. Driving device: The function of the driving device is to change the driving torque of the motor into a force on the ground through the wheel to drive the wheel to walk. It is the same as other cars, consisting of wheels, tires and suspension. Brake rigging: The braking device of electric vehicle, like other vehicles, is set for vehicle deceleration or parking. It is usually composed of brake and its control device. In electric vehicles, there are generally electromagnetic braking devices, which can use the control circuit of the driving motor to realize the power generation operation of the motor, so that the energy during deceleration braking can be converted into the current charged by the battery, so as to be recycled. Working device: The working device is specially set for industrial electric vehicles to complete the operation requirements, such as the lifting device, gantry, fork, etc. of electric forklift. The lifting of fork and the tilting of gantry are usually completed by the hydraulic system driven by motor. Electric vehicles can be divided into electric bicycles, electric mopeds and electric motorcycles.
