Wiper motor

The wiper motor is driven by the motor. The rotary motion of the motor is transformed into the reciprocating motion of the wiper arm through the connecting rod mechanism, so as to realize the wiper action. Generally, the wiper can work by connecting the motor. By selecting the high-speed and low-speed gear, the current of the motor can be changed, so as to control the motor speed and then control the wiper arm speed. The wiper of the car is driven by the wiper motor, and the potentiometer is used to control the motor speed of several gears.

The rear end of the wiper motor is provided with a small gear transmission enclosed in the same housing to reduce the output speed to the required speed. This device is commonly known as the wiper drive assembly. The output shaft of the assembly is connected with the mechanical device at the end of the wiper, and the reciprocating swing of the wiper is realized through fork drive and spring return.

What is the composition of the wiper motor？

Wiper motor is usually DC motor, and the structure of DC motor shall be composed of stator and rotor. The stationary part of DC motor is called stator. The main function of stator is to generate magnetic field, which is composed of base, main magnetic pole, commutator pole, end cover, bearing and brush device. The rotating part during operation is called rotor, which is mainly used to generate electromagnetic torque and induced electromotive force. It is the hub for energy conversion of DC motor, so it is usually called armature, which is composed of rotating shaft, armature core, armature winding, commutator and fan.
