The wiper motor is driven by the motor. Through the connecting rod mechanism, the rotary motion of the motor is changed into the reciprocating motion of the wiper arm, so as to realize the wiper action. Generally, the motor can be switched on to make the wiper work.
The windshield wiper of the car is driven by the windshield wiper motor, and the potentiometer is used to control the motor speed of several gears.
At the rear end of the wiper motor there is a small gear transmission enclosed in the same housing to reduce the output speed to the required speed. This device is colloquially 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 the fork drive and spring return.
