Abstract: A rotor for a rotating electric machine includes a hollow cylindrical rotor core and a plurality of permanent magnets. The rotor core has a plurality of magnet-receiving holes arranged in a circumferential direction thereof. The permanent magnets are received respectively in the magnet-receiving holes of the rotor core to form a plurality of magnetic poles the polarities of which alternate between north and south in the circumferential direction of the rotor core. Moreover, the rotor core further has a plurality of q-axis core portions each of which is located between one circumferentially-adjacent pair of the magnetic poles. For each of the q-axis core portions, a radially outer circumferential width center of the q-axis core portion is offset upstream in a direction of rotation of the rotor from a radially inner circumferential width center of the q-axis core portion.

Abstract: In a stator having a stator core and phase windings, slots are formed in the stator core and each slot accommodates conductors in a layer structure from one end to the other end of the slot in a radial direction of the stator core. The phase windings in one phase have conductors accommodated in a first slot and a second slot which are adjacently formed in the stator core. An electrical connection between the conductors in a n-th layer and the conductors in a (n+1)-th layer includes that the conductors accommodated in the first slot are electrically connected together, the conductors accommodated in the second slot are electrically connected together, and the conductors accommodated in the first slot are electrically connected with the conductors accommodated in the second slot. This connection eliminates a phase difference in the first slot and the second slot in a distributed winding structure.

Abstract: A rotor includes a rotor core having a plurality of pairs of magnet-receiving holes and a plurality of magnets respectively received in the magnet-receiving holes. Each pair of the magnet-receiving holes is arranged in a substantially V-shape that opens toward a stator side. For each pair of the magnet-receiving holes, there are provided a pair of corresponding magnetic flux barriers and a corresponding center bridge. The corresponding magnetic flux barriers are formed so as to respectively extend radially inward from magnetic pole centerline-side ends of the pair of the magnet-receiving holes. The corresponding center bridge radially extends between the corresponding magnetic flux barriers to separate them from each other. The corresponding center bridge is configured to include a radially inner portion and a radially outer portion located radially outward of the radially inner portion. The radially inner portion has a greater circumferential width than the radially outer portion.

Abstract: A multi-phase armature winding is made up of winding segments. Each of the winding segments includes a pair of straight sections extending straight in an axial direction of the armature winding and connecting sections which are located on axially opposed end sides of the armature winding. The connecting sections are bent and connect the straight sections together in a circumferential direction of the armature winding. The winding segment is produced by winding a conductor wire member a plurality of times. The conductor wire member is made of a bundle of wires. Each of the straight sections occupies the whole of a coil side and portions of coil ends of the winding segment. Each of the straight sections has holding portions arranged at least in coil end portions thereof. The holding portions work to tighten the wires together.

Abstract: A magnet unit includes a plurality of arc-shaped magnets arranged in a circumferential direction and a magnet holder to which the magnets are secured. Each of the magnets has arc-shaped easy axes of magnetization which extend more parallel to the d-axis in a region close to the d-axis than those in a region close to the q-axis. The easy axes of magnetization define arc-shaped magnetic paths extending therealong. The magnets are arranged to be separate from each other across the d-axis or the q-axis. Each of the magnets has a q-axis end surface facing in the circumferential direction and placed in surface-to-surface contact with that of the circumferentially adjacent magnet. Each of the magnets has an armature-remote peripheral surface which faces away from the armature. Each of the armature-remote peripheral surfaces facing an attachment surface of the magnet holder through a clearance which is filled with a resin adhesive.

Abstract: In a rotating electric machine that includes an armature with an armature coil, the armature coil is formed by winding an electrical conductor wire. The electrical conductor wire includes a plurality of element wires in a bundled state and an insulating coat covering the bundled element wires. Each of the element wires includes an electrical conductor through which electric current flows, and a fusing layer that covers a surface of the electrical conductor. In the bundled state of the element wires, the fusing layers of the element wires are in contact with and fused to one another. Between adjacent parts of the electrical conductor wire wound to form the armature coil, there are formed gaps due to differences in straightness between different parts of the electrical conductor wire. The gaps are filled with a filler.
