Wheel hub motor e.g. synchronous reluctance motor, for two or three-wheeled vehicle, has fan portion rotatably coupled in rotation direction around main rotational axis with rotor for generating airflow for refrigeration of hub motor

摘要

The motor (1) has a rotor (4) and a stator (5), where the rotor is rotatably arranged around a main rotational axis (6) relative to the stator. A wheel of a vehicle is arranged at the rotor. A fan portion is rotatably coupled in a rotation direction around the main rotational axis with the rotor for generating airflow for refrigeration of the hub motor. The fan portion is carried over a freewheel with a main rotor shaft, which supports the rotor over a bearing unit. The stator comprises a stator carrier (9).
