Working principle: By cutting magnetic lines through the rotor to generate torque, the rotor is driven to rotate, and then the internal worm gear is used to decelerate, achieving the conversion between high and low speeds. Then, the wiper arm and wiper blade are driven to perform reciprocating motion, thereby wiping away rainwater, snow, or dust on the windshield.

Structural features: Generally integrated with the deceleration mechanical part, the deceleration mechanism can reduce speed and increase torque. Its output shaft drives a four-bar linkage mechanism, transforming continuous rotational motion into left-right swinging motion. There are usually two types of materials: metal gears and plastic gears. The outer shell is mostly made of high-strength metal material, which has been treated with rust and corrosion prevention. The internal structure has good sealing, and the protection level can reach IP67/IP68, which can prevent dust, debris, and water from entering.

Performance parameters: The voltage is usually 24V, the power is around 15 to 80W, the torque is generally between 0.2 and 130, the speed ratio is between 2 and 2000, and the output speed is between 5rpm and 2000rpm. It can provide strong power and high torque, meeting the scraping needs of large windshields for bulldozers.
Application scenario: Bulldozers are mainly used in harsh environments such as construction sites and mines. The driver's cab glass is easily contaminated with a large amount of soil, dust, etc., which affects the driver's line of sight. The wiper motor can drive the wiper to work, timely clearing debris on the windshield, ensuring clear visibility for the driver and ensuring safe and efficient operation. For example, bulldozers such as Shantui SD16 and SD22, as well as Komatsu D31EX, need to be equipped with corresponding wiper motors to ensure clear visibility inside and outside the cab. Application scenarios and maintenance points of bulldozer wiper motor

Application scenarios
Rainy or humid environment: In rainy or snowy weather, the wiper motor drives the wiper blades to quickly remove moisture from the glass surface, maintaining a clear field of vision.
Dusty or muddy construction sites: Dust and mud generated during construction can easily adhere to the windshield. The wiper motor works continuously and, in conjunction with the water spray function (if any), promptly removes stains to avoid affecting the driver's observation.
Maintenance suggestions
Regularly check the wiper blades: When the rubber of the wiper blades hardens or shows scratches, it can cause uneven wiping or residual dirt. It should be replaced in a timely manner to avoid increasing the motor load due to wiper blade problems.
Cleaning and lubrication: Regularly clean the dust and debris outside the motor, check if the connecting rod mechanism is loose, and add lubricant if necessary to ensure smooth movement.
Pay attention to the operation status of the motor: If there is abnormal noise, speed or inability to start the wiper blade, it may be a motor failure or circuit problem, and it needs to be repaired in a timely manner to avoid failure under critical working conditions
