Magnet carrier for a pole housing

The invention provides an electrical connection for an electric motor having a casing which houses a drive device, embodied especially a stator in a casing interior. The drive device is contacted via a conductor, embodied especially in the form of a pin. The conductor is guided from the exterior into the interior of the casing via a casing opening. A cylindrical sealing element is provided on the casing opening in the casing interior to seal the conductor from the casing opening. The sealing element is provided with a continuous collar and a through-opening through which the conductor extends and in which the conductor is sealed in the through-opening via at least one radial sealing lip that is formed in the through-opening on the sealing element and that rests on a surface of the conductor. The conductor is then sealed towards the housing via at least one axial sealing lip that is formed on the collar and that rests on an inside of the casing. The electrical connection according to the invention can be used for a motor, especially for driving a motor cooling fan.

Electrical connection for an electric motor

An armature for a direct current motor, in particular for a permanent-magnet-excited DC motor, has an armature body, with armature teeth joined in one piece together via a short-circuit ring and offset by equal circumferential angles, each with a tooth neck for receiving an armature winding and with a tooth head that protrudes past the tooth neck in the circumferential direction. For an axial lengthening of the armature body that is simple and economical to produce, one preferably stacked flux-conducting element each, whose profile corresponds to the tooth head profile, is placed on the axially pointing end faces of the tooth heads.

A needle bearing for use in a pump has an inner race, embodied as an eccentric sleeve, needles, and an outer race with rims oriented radially inward on both of its face ends, of which one rim is intended to secure the axial position of the needles and the outer race by engagement with the inner race, in that a rim fits over one end face of the inner race. In the pump unit, the needle bearing is disposed with an axial gap from a roller bearing on a shaft of a drive motor. The rim of the outer race engages this gap.

An electric motor having a cup-shaped motor housing for containing a shaft and a motor cover that closes the motor housing. The motor cover has a peripheral section extending essentially radial to the shaft and an inner section extending essentially axial to the shaft. The inner section at least partially, radially encloses a bearing for supporting the shaft. The electric motor is fastened to a connecting block in order to be connected to a subassembly to be rotated by the shaft. The peripheral section of the motor cover and the connecting block touch each other on at least one support. The motor housing and the connecting block are axially clamped in relation to each other by means of a clamping element. The peripheral section of the motor cover is axially connected to the motor housing in detent fashion.
