Abstract: A rotor having a lamination stack including a first partial stack with first sheet metal laminations and a second partial stack with second sheet metal laminations. The laminations and partial stacks are joined axially along a center axis of the lamination stack. Each partial stack has a radially inner circumferential area and a radially outer circumferential area and a plurality of connection areas distributed in circumferential direction in mutual register at the joined partial stacks and form a common connection area. At least one of the partial stacks includes a fastening area for arranging the lamination stack at a carrier element. The lamination stack has a magnetic interaction area formed by one of the circumferential areas of the partial stacks for cooperation with a stator. The magnetic interaction area has a plurality of rotor poles with permanent magnets, which are uniformly distributed along the circumference.

Abstract: A rotor for an electric machine includes a rotor carrier having a cylindrical axial support portion which extends axially with respect to an axis of rotation of the rotor, a sheet pack which includes a plurality of lamellar sheets and is attached to the axial support portion at an attachment area, and a first weld in the sheet pack at a predetermined distance away from the attachment area to fasten a plurality of the lamellar sheets together.

Abstract: In a plurality of stator coils arranged on the yoke, each coil has a pair of ends, each end being adjacent to a respective end of an adjacent coil to form pairs of adjacent ends. A plurality of mutually insulated concentrically arranged linking conductors each has a plurality of circumferentially arranged terminal elements, each terminal element being electrically connected to a respective pair of adjacent ends to form a contact area in a common axial and radial position.
