Rotating electrical machine

A rotating electrical machine, wherein, the rotating electrical machine comprises a stator and a rotor;

• the rotor comprises a rotating shaft and magnetic poles fixed to the rotating shaft, a chamfer being provided on a radial outer surface of at least one of the magnetic poles;
• the stator comprises a stator core, the stator core being located on one side of the magnetic poles far from the rotating shaft, the chamfer overlapping with the stator core in an axial direction of the rotor;
• the magnetic poles comprise at least one pole claw, a chamfering part being provided on the outer surface of the at least one pole claw, the chamfering part forming the at least one chamfer;
• the at least one pole claw has two chamfers which are respectively a first chamfer and a second chamfer;
• wherein
• the second chamfer is located at the root of the pole claw;
• the first chamfer is located at the middle or tip of the pole claw and overlaps with the stator core in the axial direction of the rotor;
• the overlapping length of the first chamfer with the stator core in the axial direction satisfies the following relation:
• 0.01≤L2/L1≤0.3 (1)
• where L1 is the length of the stator core;
• L2 is the overlapping length of the first chamfer with the stator core.
