electric wiper on rail car

The principle of the wiper motor is: 1. Basic principle: The wiper motor is driven by the motor. The rotating motion of the motor is converted into the reciprocating motion of the wiper arm through the linkage mechanism, thereby realizing the wiper action. Generally, the motor is turned on to make the wiper work. By selecting the high speed Low speed gear can change the current of the motor, thereby controlling the motor speed and thus the scraper arm speed; 2. Control method: The car's wiper is driven by the wiper motor, and a potentiometer is used to control the motor speed of several gears; 3. Structural composition: There is a small gear transmission enclosed in the same housing at the rear end of the wiper motor, 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 to the wiper end mechanical device, and the wiper's reciprocating swing is realized throug…
