Dongfeng KR Wiper motor assembly 3741010-C5100

Integrated with a hall-effect position sensor and a built-in electronic control unit (ECU), the wiper motor enables accurate wiping angle control (adjustable 95°-115°, tolerance: ±1.5°) to ensure full coverage of the front windshield without overlapping or leaving blind spots. A key safety feature is its auto-park function—when the wiper is turned off, the motor automatically returns the blades to a fixed lower position (5° below the windshield’s horizontal midline), avoiding obstruction of the driver’s view and preventing blade damage during vehicle washing or parking in tight spaces

Equipped with a 24V high-performance DC permanent magnet motor (rated power: 85W, maximum torque: 16N·m), the assembly delivers robust driving force to handle large-size wiper blades (compatible with 750mm-800mm blades) even in extreme weather conditions (e.g., heavy rain, snow, or ice accumulation). It supports two adjustable wiping speeds—low speed (7-9 cycles per minute) and high speed (13-15 cycles per minute)—to adapt to varying rainfall intensities. The motor’s copper-clad aluminum windings (wire diameter: 0.55mm) ensure low heat generation during continuous operation (up to 3 hours), preventing overheating and extending the motor’s service life to over 6,000 working hours

The motor housing is constructed from high-impact ABS plastic (impact resistance: ≥15kJ/m²) with a fully sealed structure that meets IP6K9K protection standards—the highest level for automotive wiper motors. This design resists dust intrusion (preventing internal component jamming) and withstands high-pressure, high-temperature water jets (80℃, 80-100 bar) during professional vehicle cleaning, ensuring no water leakage into the motor even in torrential rain or high-pressure car wash scenarios. Additionally, the motor’s internal double-sealed ball bearings are lubricated with high-temperature grease (operating range: -45℃ to 125℃), maintaining smooth rotation in extreme cold (e.g., winter plateaus) or hot (e.g., desert transportation) environments

Designed for user-friendly installation, the assembly comes with pre-assembled anti-vibration rubber gaskets (reducing vibration transmission by 30%) and matched M8×25mm hexagon bolts (with lock washers to prevent loosening). The entire installation process takes 20-25 minutes with basic hand tools (socket wrench and screwdriver), requiring no specialized calibration or programming. For maintenance, the motor’s carbon brush assembly is easily replaceable via a side access cover—when brushes wear out (service life: 3,500 hours), they can be replaced in 10 minutes without disassembling the entire motor. A built-in overcurrent protection circuit also automatically cuts off power if the motor is jammed (e.g., by ice or debris), preventing burnout and reducing repair costs for fleet operators
