Wiper motor

Milling machine parts - 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 linkage mechanism, so as to realize the wiper action. Generally, the wiper can work when the motor is turned on. By selecting the high-speed and low-speed gears, the current of the motor can be changed, so as to control the motor speed and then the wiper arm speed.
The automobile wiper is driven by the wiper motor, and the potentiometer is used to control the motor speed of several gears.
There is a small gear transmission enclosed in the same housing at the rear end of the wiper motor 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 the fork drive and spring return.
