The future of electric motorcycles

electric two wheel motorcycles experienced centuries of wind and rain, is toward updating,
Jaguar motorcycle jump
Faster and safer direction.
Modern motorcycle industry to introduce a lot of advanced technology. The engine uses the world's top automotive engine technology - fuel injection means, not only to improve the power, and is more suitable for the environmental needs of contemporary society in the 21st century motorcycle pioneer. The optical communication electronic control systems, radar range automatic control systems, electric two wheel motorcycles map guidance systems, acoustic systems and other high-tech electronic muffler on a motorcycle in the use of some concepts, then the modern motorcycle become more perfect, more shocking .

Motor speed control device

Motor speed control device is set to transform the shift and direction of the electric car, and its role is to control the motor voltage or current, complete control of the motor drive torque and rotational direction.
Before electric garbage tricycle three wheel motorcycle cars on DC motor speed using the series resistance or change the motor field coil turns to achieve. Because there is a level of speed and will produce additional energy consumption or use of a motor complex structure, it has been rarely used today. Today the electric vehicle broader thyristor chopper controlled by changing the uniform of the motor terminal voltage, electric garbage tricycle three wheel motorcycle current control to achieve variable speed motor. In the continuous development of power electronics technology, which is gradually replaced by other power transistor (the GTO, MOSFET, BTR and IGBT etc) chopper speeder is. From the technology point of view, along with the application of new drive motor speed control conversion of electric vehicles for the application to DC inverter technology will become an inevitable trend.

Electric motorcycle gear

The role of the electric car is to drive the actuator motor torque transmitted to the car's drive shaft,electric two wheel motorcycles when the use of electric-wheel drive, the most part of the drive means can often be ignored. Because the motor can start with a load, so without the traditional internal combustion engine vehicle clutch on electric vehicles. Because the drive motor rotation can be achieved by converting circuit control, the electric car without internal combustion engine vehicle transmission in reverse.electric two wheel motorcycles When using variable speed control motors, electric vehicles can be ignored traditional car transmission. When using electric wheel drive, electric cars may be omitted traditional internal combustion engine vehicle driveline differential.

Motorcycle motor works

Motorcycle motor works
Motor rotation principle basis for Fleming left-hand rule, when dream 125 motorcycle a wire is placed in a magnetic field, if the current through the wire, the wire will cut the wires to generate magnetic field lines move. Current into the coil generates a magnetic field by the magnetic effect of current, so that the electromagnet in the stationary magnets continuously rotating means, electrical energy can be converted into mechanical energy. Principle of the magnetic field by a permanent magnet or another set of coils produced interact to generate power DC motor is not moving the stator,motorcycle the rotor in the direction of the force generated by the interaction of the movement. AC motor is a stator winding through the AC coils generate a rotating magnetic field, rotating magnetic field to attract the rotor together as a basic construction of a rotary movement of the DC motor including the "armature", "field magnet," "collector ring", "brush."
Armature: You can rotate around the axis of soft iron multi-turn coil winding.Electric motorcycles and scooters, Field magnet: generating a strong magnetic field of the permanent magnet or an electromagnet. Collector ring: a collector coil about two to two semicircular termination of the ring, with the coil rotation for changing the current direction of change to implement. Every half a rotation (180 degrees), the current direction on the coil to change again. Brush: usually made of carbon, collector ring brush contacts a fixed position for connection to the power supply.

Characterized by different forms of motor is not the same

According to their use of the environment and the use of different frequencies, different forms. Characterized by different forms of motor are not the same. Currently Luojia electric motorcycle motors commonly used in permanent magnet motor. China electric scooter manufacturer  The so-called permanent magnet motor refers to the motor coil using a permanent magnet excitation, do not use the coil excitation mode. Motorcycle plastic parts thus eliminating the need to work when the excitation coil power consumption, improve motor electromechanical conversion efficiency, which limited the use of onboard electric vehicles in terms of energy can be reduced with current and extend continues the course. Electric vehicle motor according to the motor is energized form can be divided into brush motors and brushless motors into two categories; mechanical structure according to the motor assembly points, generally divided into "teeth" (motor speed is high, need to go through a gear deceleration) and "toothless" (motor torque output without any slowdown) two categories.

Drive motors for electric vehicles and conventional industrial motors are different. Electric drive motor vehicles usually require frequent start / stop, acceleration / deceleration, requiring high torque at low speed or climbing, require low torque at high speeds, and require large speed range. The optimization of industrial motors are usually rated operating point. Therefore, the electric vehicle drive motor relatively unique, should be classified as a separate category.

Electric car gear and drive motor

Role cub motorcycle manufacturer electric car gear drive torque is transmitted to the car's drive shaft of the motor, when the use of electric-wheel drive, the majority gearing member often ignored. Because the motor can start with a load, so without the traditional internal combustion engine vehicle clutch on electric vehicles. Because the drive motor rotation can be achieved by converting circuit control, the electric car without internal combustion engine vehicle transmission in reverse. When using variable speed control motors, electric vehicles can be ignored traditional car transmission. When using electric wheel drive, electric cars may be omitted traditional internal combustion engine vehicle driveline differential.

The drive motor is the role of the power of the electrical energy into mechanical energy, by gear or direct drive wheels and the working device. Vertical motorcycle engine widely used in today's electric cars dc series motor, the motor has a "soft" mechanical properties, very consistent with the driving characteristics of the car. However, due to the presence of DC motor commutation spark, less power, less efficient, maintenance workload, with the development of motor technology and motor control technology, is bound to gradually than brushless DC motor (BCDM), a switched reluctance motor (SRM) and AC induction motor replaced.

Important components of electric motorcycles

Luojia electric motorcycle motors  is an important component of electric motorcycles, electric motorcycles currently in the drive field, mainly DC motor drive system, AC permanent magnet motor drive system and a switched reluctance motor drive systems wide range of applications than the cross.Excited DC motor mechanical properties is very hard, series-wound DC motor mechanical characteristics very soft, compound excited DC motor can be combined with the characteristics of both. If the same magnetic potential direction of the string and magnetic potential field winding and field winding, called cumulative compound excited DC motor; in the opposite direction, called differential compound excitation DC motors.

110cc cub engine  The mechanical properties can learn from his excitation type mechanical characteristic equation, depending on the shape of the curve of the potential strength of the string excitation.

Scooter engine Systems with high efficiency, high control accuracy, high torque density and so has a very high value in the electric vehicle electric drive system. However, due to the complexity of motor parameters of electric vehicle operating conditions caused by changes in temperature, speed and other factors have a significant impact on the control performance of the system.
