Abstract:
1. A permanent-magnet synchronous motor, comprising: a rotor having permanent magnets; and a stator having a stator yoke in which stator teeth with interposed stator grooves are arranged, wherein: wherein the stator teeth are arranged as plates in the axial direction of the stator in the sequence of a stator star having connecting bridges followed by at least one plate of stator teeth without connections; wherein the rotor comprises at least two rotor packets which are arranged in the axial direction of the rotor the at least two rotor packets being arranged rotated from one another by an offset angle about a rotor axis; and wherein the offset angle is less than or equal to half of a number of stator grooves, the offset angle being the angle between the first and last rotor packets if there are more than two rotor packets.
