The motor is a very big classification,and its form is different according to the difference of its use and frequency.Different types of motors have different characteristics.

The motor is divided into brushless motor and brush motor according to the power on form of the motor.The brush motor is mainly a low-speed high torque motor.There is no transmission gear to avoid wear of the machine.There is almost no noise during operation.However,the starting current of the brushless motor hits heavily and the control system layout is complex.According to the machine layout of the motor assembly,it is generally divided into two categories:"toothed"(the motor speed is high,and the demand is delayed by the gear)and"toothless"(the motor torque output is not delayed in any way).At present,there are a large number of electric bicycles on the market.The motor used in electric scooters is the motor driven one

The electric vehicle motor uses a new type of permanent magnetic material,which is a kind of permanent magnetic material with very large magnetic energy contained in the unit volume of all current magnetic materials.With a magnetic flux up to 320,7 drive channels,12 drive combinations,56 magnetic energy levels,and 3 CPV energy-saving control modules,it realizes the perfect combination of super power and ultra-low energy consumption of the magnetic energy motor,and innovatively handles the technical difficulties of high flexibility and short mileage of ancient magnetic energy and electricity.

Electric vehicle motor

The electric vehicle motor is a motor with long life and large torque,which can meet any complicated road conditions.The motor combines the driving wheel and motor into a whole,which not only has a beautiful appearance.

There are three types of electric drive modes for electric bicycles:1.friction drive;2.Middle axle driven type;3.Electric wheel hub type.Due to the advantages of small size,light weight,low energy consumption and relatively high compliance,the electric wheel hub drive mode uses technology to improve the brush life.The motor has high compliance,and the control system is clear and simple.At present,most domestic electric bicycles use this mode.

Permanent magnet DC motors are widely used in electric vehicles.The so-called permanent magnet motor means that the motor coil is excited by permanent magnet instead of coil excitation.In this way,the electric energy consumed during the operation of the excitation coil is saved,and the electromechanical conversion of the motor is improved.For the electric vehicle with limited vehicle power,the driving current can be reduced,and the driving range can be extended.

The running noise of the brush gear hub motor and the brushless gear hub motor increases first.The gears in the motor have probably been replaced.All tooth surfaces of the gears should be coated with grease to achieve a low conflict and the benefits of lubrication and noise reduction.As each planetary gear is equipped with a bearing,the lubricating grease used in the gearbox can not penetrate or the damping is too large,and too large damping is easy to cause the sign of oil throwing.
