ELECTRIC DRIVE MOTOR

摘要

The present invention relates to an electric drive motor that comprises an outer rotor (11) as well as a stator (12) comprising a base body (13) made of a thermo-conductive material. This base body comprises a receiving hub (131) for the rotor (11) as well as a support (132) which is capable of radial displacement away from said hub. The support is designed for receiving a circuit board (19) which is fitted with electronic components and is mounted on the support (132) side opposite from the rotor (11). The purpose of this invention is to improve the draining of excess heat generated by the electronic components. To this end, a plurality of cooling vanes (27) is provided on the radial face of the support (132) in the rotor (11) direction.
