An electromagnetic device used to convert mechanical energy into electrical energy Wiper motor is driven by the motor, and 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 motor can be connected to make the wiper work. By choosing high speed and low speed, the current of the motor can be changed, so as to control the motor speed and then control the speed of the wiper arm.
The car wiper is driven by the wiper motor, with potentiometer to control the motor speed of several gears.
At the rear end of the wiper motor is a small gear transmission enclosed in the same housing, which reduces 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 of the wiper end, which realizes the reciprocating swing of the wiper through the fork drive and the spring return.
