Brogen Electric Bus Motor 180kW Powertrain BG-Motor-OEMA80F

The OEMA80F is our entry-level high-speed drive motor designed specifically for 6–7 m city buses, minivans, and 6–8 T light trucks. Utilizing an advanced hairpin (flat-wire) stator winding that dramatically reduces copper fill losses and a high-reluctance-torque rotor topology, the motor achieves a peak efficiency of ≥98% — among the highest in its displacement class. The high-sinusoidal rotor profile combined with aerospace-grade dynamic balancing suppresses primary NVH orders to ≤65 dBA, delivering a noticeably quieter cabin experience. A fully sealed anti-condensation structure with mud/sand exclusion rings and a swash water ring achieves IP68 protection (2 m submersion for 72 h), the highest protection rating in the commercial-vehicle segment. Operating life is designed to match vehicle lifespan (up to 20 years / 2 000 000 km) via high-temperature-resistant magnetic circuit structures and adaptive operating-condition control. Weight is just 49 kg with a compact Φ266×270 mm footprint, making integration into space-constrained chassis straightforward.
