Don't you understand the principle of wiper motor?
The wiper motor is more complicated among so many motors in our car, because there is a return position. Today, Zhuo Meng (Shanghai) Automobile Co., Ltd. will take you to understand the principle of this wiper motor! To know the principle of a component, you must first know what wires are on it. Common ordinary wipers are five wire and four wire, one positive, one negative, one return, two motor wires, one high-speed and one low-speed. The four wires are missing a negative, and the motor body is grounded. Two motor wires, one high-speed and one low-speed, gap gear and low-speed gear share one wire, and the remaining three are for the return plate. When the iron sheet on the return plate is negative, the return line is negative, when the iron sheet is positive, the return line is positive, and when the iron sheet is positive, the return line is negative. As long as it does not return to the initial position, the iron sheet is positive, The return line is also the positive pole. At this time, the positive pole on the return line will continue to supply the motor through the switch until it returns to the initial position, and the return line becomes the negative pole. At this time, the motor stops working!
