Abstract:
To provide a rotary electric machine capable of reducing magnetic leakage fluxes from a bridge.SOLUTION: A rotary electric machine is constituted so that a core area A arranged on an inner peripheral side to a hole 40 and a core area B arranged on an outer peripheral side to the hole 40 are mechanically coupled with each other by at least two bridges, a first bridge 51 and a second bridge 52 spaced apart in a circumferential direction from a magnetic pole center. When a distance between the first bridge 51 and a connection part 102 with the core area A of the second bridge 52 is considered as L1, and a distance between the first bridge 51 and a connection part 101 with the core area B of the second bridge 52 is considered as L2, a relation of L290°, θ2>90° are satisfied. When a distance connecting ends in the circumferential direction of the core area B is considered as L3, a relation of L2
