The invention relates to an electric motor with a stator and an external rotor, comprised of a rotor bell and a rotor cover that acts as a fan wheel. The rotor bell has several apertures in its bell floor. The rotor cover has several exhaust ports. The rotor cover is shaped like a plate and consists of a plate base and an annular wall. The exhaust ports are preferably evenly distributed in the annular wall. The inside of the plate base of the rotor cover that faces the rotor bell has several radially extending interior blades that are fixedly connected to it.

Electric motor with cooling ventilator effect

A method and an apparatus for regulating the operating temperature of an internal combustion engine, wherein a cooling fluid is transported in a circuit through the internal combustion engine by means of a cooling fluid pump driven by an electric motor. The electric motor can be operated with a power dissipation loss which is increased in comparison with its nominal operation and the waste heat produced in that situation is transmitted to the cooling fluid.
