Abstract:
An electric drive motor with a rotor in the form of an external rotor and with a stator, which has a base body comprised of heat conductive material. A bearing hub for the rotor and a support that extends radially away from the hub and is for containing a printed circuit board. The printed circuit board is equipped with electronics and is disposed on a side of the support oriented away from the rotor for the sake of an improved removal of the dissipated heat that is produced in the electronics, a multitude of concentric cooling ribs are embodied on the radial surface of the support oriented toward the rotor.
