摘要： A permanent magnet motor includes a P-pole-implanted permanent magnet rotator containing a ferrite magnet in a laminated silicon steel sheet, wherein, at one pole, a U-shaped permanent magnet comprising three parts, and, at the outer periphery of the U-shaped magnet, one outer-periphery permanent magnet disposed longitudinally in the peripheral direction are provided to generate permanent magnet torque. At one pole, the permanent magnet rotator generates reluctance torque using two salient poles formed between the U-shaped permanent magnet and the outer-periphery permanent magnet. One central salient pole is formed between the adjacent poles. A stator comprises an M-phase stator winding that is a distributed winding, and a stator core having Ns slots. The ratio of Ns/P/M is a common fraction. When the width of the center salient pole is set to τcp and the slot pitch of the stator core is set to τs, τcp is smaller than τs.

摘要： Torque is improved in a composite torque rotating electric machine that uses permanent magnets having a low residual magnetic flux density such as ferrite magnets, and includes: a stator comprising armature windings arranged at a fixed interval at multiple positions on the inner periphery; a rotor which has a permanent magnet in a cylindrical core comprising laminated magnetic steel sheets and is arranged inside of the stator; and magnetic flux blocking units provided across the circumferential direction on the outer periphery of the rotor that block the closed loop magnetic flux generated around the stator windings. The magnetic flux blocking units can be multiple permanent magnets, with a non-magnetic body such as an air gap disposed between them. The distance between the permanent magnets and the non-magnetic part can be smaller than the interval at which the armature windings are arranged.

摘要： In a rotating electric machine, each phase of a plurality of three-phase windings is divided into a plurality of partial windings, disposed on a stator core. For example, the partial windings of the U-phase are distributively arranged on four U-phase winding areas 2U1 to 2U4, and on each of these winding areas, two partial windings overlap through a pair of slots between which two teeth are interposed. At each coincident location of a pair of slots, two partial windings of different three-phase windings overlap. For example, a pair of slots on the U-phase winding area 2U1, a partial winding UA1 of a U-phase winding UA and a partial winding UB3 of a U-phase winding UB overlap. At a pair of slots on the U-phase winding area 2U1, a partial winding UG2 of a U-phase winding UG and a partial winding UB2 of a U-phase winding UB overlap.
