Abstract: The disclosure relates to a rotor (1) and an electric motor having the rotor. The rotor is equipped with a permanent magnet (6) extending around an axis of rotation of the rotor, on which a plastic overmolding (3) is provided, which defines a shaft passage (10) for the fastening receptacle of a motor shaft (14) of the electric motor along the axis of rotation, and wherein a press-fit bushing (2), into which the motor shaft can be pressed by a press fit and can be fixed on the rotor, is arranged directly adjoining the shaft passage (10) formed by the plastic overmolding (3).

Abstract: An electric motor (10) has a stator (20) having a number S of stator poles (21, 22, 23, 24, 25, 26); a rotor (40) having a rotor magnet (40?), which rotor magnet (40?) has a number R of rotor poles (41, 42, 43, 44, 45, 46), R being equal to S, and the rotor (40) or the stator (20), or both, exhibiting a magnetic asymmetry. The asymmetry facilitates startup. The electric motor has a single-phase winding arrangement (30) with first (11), second (12) and third (13) terminals. Current can be made to flow, selectively, from either the first or the second terminal, through certain coils, to the third terminal (13). There is an output stage (50), preferably an H-bridge. The W total coils comprise a plurality of subgroups (TG1, TG2) of coils. A method for current flow through an electric motor utilizes these sub-groups (TG1, TG2) for current flow.
