摘要:
A rotary electric machine, in which α>β is established when the teeth portion has a width α in a circumferential direction thereof, a rotation center of the rotor and one of corners, which is on a rotor surface side, on both ends of each of the permanent magnets are connected by a straight line, a center between an N-pole and an S-pole of the permanent magnets is on a q-axis, and an angle formed by two straight lines on the q-axis side is β, a first bridge part is provided between a flux barrier provided at the rotor core and the rotor surface, and γ>δ is established when the first bridge part has a minimum width γ, and the flux barrier has a minimum width δ on the q-axis.
