    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： 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： The permanent magnet embedded rotating electrical machine includes a rotor and a plurality of flat permanent magnets. The rotor has on an outer periphery thereof a plurality of pairs of concave portions and a plurality of convex portions. Each of the convex portions is located between the pair of concave portions. The concave portions are formed at radially outward of respective adjacent magnetic pole ends of the permanent magnet. A bridge is provided in the rotor at an angular position about an axis of the rotor between opposed magnetic pole ends of two adjacent permanent magnets. Each concave portion at radially outward of the magnetic pole end of the permanent magnet is located close to the center of the same permanent magnet in relation to the bridge next to the permanent magnet in the circumferential direction of the rotor.

    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.

    摘要： An armature for use in a motor has a plurality of teeth, a plurality of slots and coils of three kinds of phases. A plurality of the slots is formed between the coadjacent teeth. The coils of three phases are wound around the teeth. The armature has a coil structure, according to which radial force acting on a specific tooth is greater than radial force acting on another tooth. A peak value of the radial force acting on the specific tooth is approximated to a peak value of the radial force acting on another tooth in such a manner that a flux path in and/or adjacent to the specific tooth is made narrower than a flux path in and/or adjacent to another tooth.
