More Information
Summary:A rotating electric machine including circumferential portions respectively corresponding to magnetic pole centers of permanent magnets and defined along the outer circumference of the rotor at a plurality of locations, with each circumferential portion extending along part of a virtual circumferential surface, which is coaxial with the rotor. The circumferential portions are spaced from one another in the circumferential direction. Convex portions connect adjacent pairs of the circumferential portions. Each convex portion is located radially inward from the circumferential surface, projects in a radially outward direction, and includes angled portions directed in the radially outward direction. The rotating electric machine suppresses decrease in the average value of the output torque and does not use reluctance torque to increase the average value of the output torque.
