    摘要： An inverter system providing both an improvement in the voltage utilization factor and a reduction in the switching loss uses a two-phase switching method. In the inverter system, an .alpha.-axis voltage command value; v.sub..alpha.r and a .beta.-axis voltage command value v.sub..beta.r are input to a stop phase selection means. Six sections are judged based on the values v.sub..alpha.r and v.sub..beta.r to select phases for which it is allowable to stop pulse width modulation control in a two-phase switching method. Then, a phase having the largest absolute value of current is selected among the phases for which it is allowable to stop pulse width modulation control using a U-phase current i.sub.u and a V-phase current i.sub.v. This information is a control mode S. Based on these, two-phase switching calculations are performed by a dead-time compensation calculation means and a pulse width modulation generating means. By doing so, the switching loss can be reduced.

    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： The present invention comprises a stator, and a rotor which is disposed oppositely to the stator with a gap interposed. The stator comprises a stator core, and a distributed stator winding mounted to the stator core. The stator core comprises a ring-like yoke core, and a plurality of teeth cores which protrude from the yoke core in the radial direction. The rotor comprises a rotor core, and a plurality of permanent magnets embedded in the rotor core. A pair of non-magnetic portions is created inside the rotor core and on both sides of the circumferential width of a permanent magnet for one magnetic pole. In the rotor core located on the stator side of the pair of non-magnetic portions, a pair of magnetic paths is created as the result of the creation of the pair of non-magnetic portions. Furthermore, a groove or hole is created on the outer circumferential portion of the rotor core and between the adjacent magnetic poles.
