Rotor for an electrical machine

A rotor for an electric machine, comprising:

• a plurality of annularly formed laminated core segments, which are arranged in succession in a longitudinal direction of the rotor;
• a plurality of pockets, at least one of the plurality of pockets formed as part of a corresponding one of the plurality of annularly formed laminated core segments;
• a plurality of pole components, each of the plurality of pole components disposed in a corresponding one of the plurality of pockets, each of the pole components having a side face parallel to the longitudinal direction of the rotor;
• a pole assembly formed by each of the plurality of pole components arranged in succession in the longitudinal direction of the rotor, the pole assembly further comprising:
• a first subassembly having more than one of the plurality of pole components;
• a second subassembly having more than one of the plurality of pole components;
• and
• a third subassembly having one of the plurality of pole components, the third subassembly arranged between the first subassembly and the second subassembly;
• a first offset, the first offset being the distance between the side faces of each of the pole components of the first subassembly, the first offset formed by the plurality of annularly formed laminated core segments arranged offset from one another in the circumferential direction in such a way that the plurality of pole components of the first subassembly are arranged offset from one another in a first direction;
• a first maximum offset being the combined sum of each first offset of the plurality of pole components of the first subassembly;
• a second offset, the second offset being the distance between the side faces of the plurality of pole components of the second subassembly, the second offset formed by the plurality of annularly formed laminated core segments arranged offset from one another in the circumferential direction in such a way that the plurality of pole components of the second subassembly are arranged offset from one another in such a way in a second direction, which is contrary to the first direction;
• a second maximum offset being the combined sum of each second offset of the plurality of pole components of the second subassembly;
• and
• a third offset, the third offset being the greater spacing from the side face of the pole component of the third subassembly in the axial direction of the rotor to either the side faces of the plurality of pole components of the first subassembly or the side faces of the plurality of pole components of the second subassembly;
• wherein the amount of the third offset is smaller than the amount of the first maximum offset and, the third offset is smaller than the amount of the second maximum offset.
