Patent number: 11223251Abstract: 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.Type: GrantFiled: May 25, 2018Date of Patent: January 11, 2022Assignee: Schaeffler Technologies AG & Co.

Patent number: 11218039Abstract: 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.Type: GrantFiled: February 28, 2018Date of Patent: January 4, 2022Assignee: Schaeffler Technologies AG & Co.

Publication number: 20210143704Abstract: 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.Type: ApplicationFiled: April 23, 2019Publication date: May 13, 2021Applicant: Schaeffler Technologies AG & Co.
