摘要： PROBLEM TO BE SOLVED: To provide a rotating electric machine which can reduce noise.SOLUTION: In a rotating electric machine comprising wave stator windings and a rotor, slot conductors are connected together such that each crossover conductor 233b extends across slots at Np=N+1 (Np: slot pitch, N: number of slots per pole) at one coil end while extending across the slots at Np=N-1 at the other coil end. Each stator winding has a set of slot conductor groups 234, each comprising slot conductors 233a of the same phase. The slot conductors 233a are inserted in slots 237 such that layers L1 to L4 are arranged adjacently to each other. When the number of layers is 2×NL, the number Ns of slots is set to Ns=NSPP+NL (NSPP: number of slots per pole per phase). The rotor has variable magnetoresistance sections at positions displaced by prescribed amounts in the circumferential direction from q-axes. The amounts of the displacement vary according to the positions of auxiliary salient poles so as to cancel out torque ripples with each other when electric power is supplied.

摘要： PROBLEM TO BE SOLVED: To greatly reduce cogging torque in a permanent magnet type synchronous motor.SOLUTION: In a permanent magnet type synchronous motor subjected to a skew of the stage number by which a fundamental wave determined by the least common multiple of the number of poles and the number of slots is divided into a plurality of waves, a nonmagnetic substance which prevents leakage of magnetic flux between each stages is interposed between each stages of the skew. Thereby, the fundamental wave of cogging torque can be surely canceled and the cogging torque can be greatly reduced.
