28V 100A Bus Alternator AV1144 Heavy Duty Coach Generator For Yutong Bus Replacement Parts

Hollow open-frame aluminum housing with dense heat dissipation slots forms a three-dimensional air cooling channel. It rapidly dissipates heat generated by the stator copper winding during high-load operation, effectively reducing winding overheating and burnout risks for long-hour continuous operation of coaches.

High-purity enameled copper wire stator coil delivers stable power output. Low internal resistance reduces power loss, ensuring stable charging voltage under idle speed, high speed and multi-electrical equipment load, protecting vehicle batteries and on-board electrical appliances.

Integrated black rectifier bridge and IC voltage regulator maintain constant 28V output voltage. Strong anti-interference performance adapts to bumpy roads, voltage fluctuation and high-temperature engine compartment environment, avoiding overcharging or undercharging of the storage battery.

Precision cast aluminum mounting lugs with reserved mounting holes realize direct bolt-on replacement without modification. The multi-groove pulley matches the original engine drive belt perfectly to prevent belt slipping and abnormal wear.

Thickened insulating terminals and dustproof terminal cover prevent short circuit caused by mud, water splash and dust ingress, suitable for long-distance passenger transport, construction vehicles and other harsh working scenarios.
