摘要

The electrical machine has rotors (2,3) that are rotationally connected to stator (1) about rotational axis (6). An air gap (7,8) is generated between stator and respective rotor, and the stator is located between rotors, while viewing in main extension direction (H1). A groove pair is located at respective tangential position in main extension direction (H1). The rotors are viewed tangentially to rotational axis around which rotor poles are arranged. A magnetization of rotor poles alternates at tangential positions based on rotors co-rotating coordinate system.
