An electric motor comprises a cylindrical housing, a stator comprising multiple stacked metal sheets and mounted in the housing, and a rotor which sits on a shaft, which is rotatably mounted in a respective bearing shield provided at a first end or at a second end of the housing. The housing is die cast. The stator protrudes into a wall of the housing with a depth. The depth is smaller than a thickness of the wall. A method for producing such an electric motor is also disclosed.

Electric motor

An electrical motor includes a housing, a stator seated in the housing, wherein the stator includes a plurality of stator teeth which extend in the radial direction toward the rotor, a yoke that connects the stator teeth is arranged in such a way that a plurality of first clearances are formed between the housing and the yoke and a plurality of second clearances are formed between the yoke and a free end of the stator teeth, and a coolant guide in contact with at least one axial lateral surface of the yoke, wherein the stator is in interlocking contact with the inner side of the housing.

Electrical machine with cooling

The electrical motor includes a stator and a rotor configured to be rotated about an axis wherein the rotor includes at least three rotor subsegments, wherein a first and second rotor subsegment can be turned relative to one another about the axis in response to a rotation speed range being above a predetermined threshold value of a rotation speed of the electrical machine.

Electric motor with turnable rotor segments for reducing the magnetic flux

A rotor for an electrical machine includes a rotor body and an axis of revolution which extends in an axial direction and about which the rotor body is rotatable. The rotor further includes an outer casing surface which delimits the rotor body, at least one pole arrangement, and a movement mechanism for the at least one pole arrangement. The movement mechanism is designed such that the at least one pole arrangement is movable about a rotation axis which is oriented substantially parallel to the axis of revolution of the rotor. The at least one pole arrangement is also movable about the rotation axis in addition to rotation about the axis of revolution of the rotor.

Permanent magnet energized motor with rotatable bar magnets

An internal rotor for an electric machine includes a rotational axis, an outer circumferential face which delimits the internal rotor, a pole arrangement comprising a centroid, and an actuating mechanism for moving the pole arrangement towards the rotational axis or away from the rotational axis to set a first spacing between the outer circumferential face and the centroid. In an example embodiment, the actuating mechanism has an actuator for moving the pole arrangement. The actuator has a hydraulically operable piston, a pneumatically operable piston, an electric motor actuator, or converts an axial force to a radial force. In an example embodiment, the actuating mechanism is operatively connected to the pole arrangement. The actuating mechanism is arranged between the rotational axis and the pole arrangement, or the actuating mechanism is arranged between the outer circumferential face and the pole arrangement.

Electric motor with switchover elements in the magnetic circuit

An electronic system housing for an E-axle drive of a motor vehicle is disclosed. The electronic system housing comprises a power electronic system received within the electronic system housing for processing voltage in high voltage systems. At least one low voltage component is further received within the electronic system housing.
