An electric motor, in particular a radiator fan motor of a motor vehicle, has a rotor which is mounted such that it can rotate in relation to a stator, a motor mount which has an electronics compartment for accommodating a converter electronics system, and an electronics compartment cover. The electronics compartment cover has a peripheral sealing groove into which a peripheral edge of the electronics compartment engages by way of a corresponding sealing web in order to reliably seal off the electronics compartment.

A dynamoelectric machine having mechanical field weakening is provided. A design that is advantageous in terms of efficiency is brought about by a machine having a stator (), a rotor () that is spaced from the stator () by an air gap (), permanent magnets () for generating an exciter field in the air gap (), which permanent magnets are arranged in magnet pockets () on the rotor (), and displaceable flux-guiding elements () guided in radially extending grooves (), wherein the density of the exciter field in the air gap () can be influenced by the radial position of the flux-guiding elements, and wherein the leakage flux-guiding elements () are arranged underneath the permanent magnets () when viewed in a radial direction.

A dynamoelectric permanently excited machine having the possibility of mechanical field weakening. The machine includes a stator (), a rotor () spaced apart from the stator () by an air gap (), permanent magnets () arranged on the rotor () for generating an excitation field in the air gap (), and a centrifugal-force-controlled field-weakening mechanism for weakening the excitation field in the air gap () in accordance with rotational speed. In order to increase the operational safety of systems that are driven by such a machine, the machine also includes a signal input for a fault signal and an actuator for controlling the field-weakening mechanism independently of rotational speed.

A radiator fan of a motor vehicle, in particular a main fan, contains a fan wheel which has a hub and an electric-motor rotor which is attached thereto in a form-locking manner. At least one connecting dome is formed integrally on the rotor, which connecting dome protrudes through a corresponding cutout of the hub and is deformed on the free end side in a rivet-shaped manner in order to produce the form-locking connection.
