External rotor motor for driving ventilators, the motor having an overhung rotor and a stator connected with a motor flange. The stator has a stator winding and stator laminations, and is equipped with an insulating layer made of plastic and sprayed on the stator laminations. The insulating layer extends over the inner side of an axial stator borehole of the stator laminations and, at least in areas, over the front sides of the stator laminations. A rotatable rotor shaft extends through the axial stator borehole, and the rotor shaft is connected with the rotor in a fixed manner on the end opposite the motor flange. At least one metal heat conducting element is provided which, on one end, directly contacts or engages the stator laminations for conducting heat from the limitations and, on the other end, contacts the motor flange for the removal of the heat to the motor flange. |
