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.
