摘要： A synchronous machine comprises a stator and a rotor that faces the stator and rotates on a shaft thereof in a circumferential direction The rotor has magnetic salient poles that generate reluctance torque and magnet-originating magnetic poles that generate magnet torque by using permanent magnets embedded in the rotor, The machine comprises means for shifting a magnetically substantial central position of magnetic flux emanating from the permanent magnets in the circumferential direction, by an electrical angle π/2 plus a predetermined angle Δθ, from a reference position taken as a central position between paired magnetic salient poles composing each magnetic pole of the machine among the magnetic salient poles. Hence a maximum amplitude of a sum between a harmonic component of the magnet torque and the reluctance torque is changed from that obtained at the reference position without the shift.

摘要： A stator coil includes a belt-shaped winding band and a same-layer bridging portion. The winding band makes one or more rounds, while turning back in the axial direction a plurality of conductor wires which are aligned in parallel at a pitch of electric angle π (pi). The same-layer bridging portion connects a pair of the conductor wires which are of the same phase at the end portion of the winding and which are arranged in the same layer of the slot. Such arrangement enables forming a compact multi-phase stator coil.

摘要： An alternator has a rotor and a stator. The stator has a cylindrical armature core wound with an armature wiring. The core has slots disposed along a circumferential direction of the core so as to surround the rotor. Each slot extends in an axial direction of the core and has accommodation regions aligned along a radial direction of the core. Each region receives the wiring. The regions of each slot includes an innermost region and an outermost region, respectively, disposed on both ends of the slot in the radial direction. The wiring has end portions, respectively, drawn out from the outermost regions of different slots, and the wiring has a return portion of which both ends are drawn out from the innermost regions of two different slots.
