Publication number: 20220136563Abstract: A complex ring element includes first and second rings arranged such that their axes lie on a shared axis and disposed adjacent to one another when viewed in the direction of the shared axis, with one of the first and second rings representing a shaft of a rotor or being connected to a shaft of the rotor. A connecting element made of metal interconnects the first and second rings of metal such that outer peripheral surfaces of the first and second rings are partially overlapped when viewed in the direction of the shared axis. The connecting element is configured to extend circumferentially as viewed in the peripheral direction about the shared axis and is produced by an additive application method.Type: ApplicationFiled: December 19, 2019Publication date: May 5, 2022Applicant: Siemens AktiengesellschaftInventors: REINER SEUFERT, ROLF VOLLMER

Patent number: 10097055Abstract: A permanently-excited dynamoelectric machine includes a stator and a rotor supported for rotation about an axis. The stator has a winding system, which is embedded in grooves of a material forming a magnetic return path and interacts electromagnetically with permanent magnets of the rotor via an air gap between the stator and the rotor. The permanent magnets are disposed on the rotor, with each individual permanent magnet, on a side facing towards the air gap, having a North and South pole. The rotor, viewed in the circumferential direction, has a pole coverage by the permanent magnets of 100%, i.e. that the permanent magnets viewed in the circumferential direction, are arranged substantially without gaps.Type: GrantFiled: August 31, 2015Date of Patent: October 9, 2018Assignee: Siemens AktiengesellschaftInventors: Reiner Seufert, Rolf Vollmer
