• Specifiion

• Function and Appliion

1. Power Transmission
The core function of the 22B-54-28731 wiper motor is to convert electrical energy (from the equipment’s battery or electrical system) into mechanical motion. It generates rotational force to drive the wiper arm and blade assembly, enabling them to sweep across the equipment’s windshield or operator cabin window.

2. Wiper Operation Control
Sweeping Motion: The motor facilitates the back-and-forth or oscillating movement of the wiper blade, ensuring consistent coverage of the glass surface. This motion is critical for clearing rain, snow, mud, dust, or debris that could obstruct the operator’s visibility.
Speed Regulation: In many configurations, the motor supports multiple speed settings (e.g., low, high, or intermittent), allowing the operator to adjust wiper performance based on weather conditions (e.g., light drizzle vs. heavy rain).
