摘要： A stator includes a stator core, a stator winding, and insulation paper sheets. The stator winding is constructed by forming a Y connection of phase windings each of which is constructed by inserting conductor segments into slots from a lower end side of the stator core and joining distal end portions of the conductor segments which protrude from an upper end side of the stator core. One of the insulation paper sheets is disposed between radially adjacent ones of joint portions that constitute a group of joint portions in a U-phase winding that are the nearest to a U-phase terminal. In the same manner, the other insulation paper sheets are disposed with respect to a V-phase winding and a W-phase winding. Surfaces of the other joint portions are covered with an insulation resin. Insulation paper sheets are disposed between joint portions that need long creepage distances and the insulation resin is used to cover surfaces of the other joint portions that do not need a long creepage distance.

摘要： A reluctance motor is described in which stator coils are driven with sinusoidal, or substantially sinusoidal, waveforms. Preferably, the spread angle of the stator poles is less that the spread angle of the rotor poles. More preferably, the spread angles of the stator poles &thgr;S and the rotor poles &thgr;r are set such that &thgr;S is approximately equal to 2&pgr;/(m·Nr) and &thgr;r is about (&thgr;S+&pgr;/Nr)/2≦&thgr;r≦(&pgr;/Nr), respectively, wherein Nr is the number rotor poles and m is the number of phases of electric current. By supplying a sinusoidal, or substantially sinusoidal-like, driving waveform to the stator coils, torque becomes relatively constant and does not depend on the angular position of rotation of the rotor. Therefore, torque ripple is effectively decreased.

摘要： A system for supplying electric power to an electrically powered vehicle includes a feeder disposed along a structural member as a guide rail that guides the vehicle. The vehicle has an electric power receiving unit that receives electric power from the feeder on a non-contact basis. The electric power receiving unit has a ferrite core with a coil. A ferrite sheet is disposed on a surface of the structural member in such a manner that the ferrite sheet is opposite to the electric power receiving unit. The feeder is surrounded by the ferrite core and the ferrite sheet. When an AC current is supplied to the feeder, a magnetic flux that penetrates the ferrite core and the ferrite sheet varies, thereby causing electromotive force to occur in the coil.

摘要： A rotary electric machine system includes: a stator that has multi-phase stator coils and that generates stator magnetomotive forces based on respective stator currents having different phases supplied to the multi-phase stator coils; a rotor on which rotor coils are wound such that magnetic poles are formed by rotor currents generated in response to the stator magnetomotive forces generated by the stator; a regulating unit that regulates a flow direction of each of the rotor currents to one direction to thereby regulate a polarity of each of the magnetic poles; and a control unit that controls currents supplied to the stator coils on the basis of a target torque. The control unit superimposes a pulse on the stator currents to adjust the ratio of each of the stator currents and each of the rotor currents so as to minimize a copper loss in the stator and the rotor.
