摘要： A plurality of convex portions are located inside of a virtual circumferential surface. Each convex portion connects an adjacent pair of circumferential portions with each other. Each convex portion is an arcuate curve bulging radially outward. Each convex portion defines a minimum radius. A difference between a radius R and the minimum radius is a depth Dh. Dhr=Dh×25.5/R. A range of an angular width A in relation to circumferential portion and a range of the depth Dh are set by the following expression, (5.6×Dhr+11.3)°×6/p≦A

摘要： A housing of an electric motor includes an inner circumferential surface, which includes recesses arranged along the circumferential direction. On an outer circumferential surface of a stator core of a stator are provided protrusions arranged along the circumferential direction. Fitting each protrusion to the corresponding recess fixes the stator core to the housing. A rotor is provided radially inward of the stator. In a state where each protrusion is fitted to the corresponding recess, a pair of side surfaces of each protrusion are retained by a pair of inner side surfaces of the corresponding recess in the circumferential direction of the housing. A gap is formed between an end face of each protrusion and an inner bottom surface of the corresponding recess facing the end face along the entire surface of the end face.

摘要： 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.

摘要： An electric motor includes an annular housing and an annular stator core having the inner periphery the shape of which differs from a perfect circle. The stator core is supported by the housing in such a manner that the outer periphery of the stator core and the inner periphery of the housing are partially in contact with each other. The inner periphery of the stator core is deformed to become close to the shape of the perfect circle when the stator core is securely fitted in the housing by shrink fitting.
