Abstract:
A motor with a stator (St) that has a number of magnet poles (P1 to P8) and a rotor (R) with a corresponding number of permanent magnet poles (M1 to M8), in which an air gap is formed in the region between the stator (St) and rotor (R), the stator is provided with gearing teeth in order to reduce a torque between the stator and rotor, wherein the pole structure of the stator (St) and rotor (R) is designed to be essentially symmetrical in a circumferential direction and the magnet poles (P1 to P8) of the stator (St) are provided at least over a partial region of the air gap with the gearing teeth, and wherein the magnet poles (P1 to P8) of the stator (St) constitute pole pairs in which the gearing teeth are disposed offset from one another at least in partial circumferential regions.
