Abstract: A stator provided with coils that are interconnected by distributed windings on a stator core of a rotating electric machine having: a stator core module comprising a stator core wherein one part of a linear conductor portion of the coil is disposed in a slot; and a mold end, formed through insulator molding of a coil end portion of the coil, wherein: the linear conductor portion of the stator core module comprises a first junction portion at a conductor end portion that is disposed protruding from the stator core toward the mold end side; and the coil end portion of the mold end comprises a second junction portion at a conductor portion disposed protruding from an end portion of the insulator mold toward the stator core module side; having a structure wherein the first junction portion and the second junction portion are joined.

Abstract: A segment conductor that is a conductive element of a coil wound in a distributed winding in a stator core of a rotating electric machine is formed, through press forming and is provided with a pair of straight conductor portions and a bent conductor portion that connects together one end side of the pair of straight conductor portions. Moreover, one part of the segment conductor is formed, through press forming, so as to be thinner than another part. Specifically, a part that is exposed from the stator core is formed, through press forming, so as to be thinner than a part that is contained in a slot of the stator core. The stator has a structure wherein a plurality of segment conductors are disposed in a distributed winding in the stator core. The rotating electric machine is equipped with this stator. The vehicle is equipped with this rotating electric machine.

Abstract: A micro-step drive system of a five-phase stepping motor is disclosed. When Io is a constant, a unit time interval is 1, a remainder obtained by a time variable divided by 10 is t and an arbitrary constant is .alpha. (0.ltoreq..alpha.<10), each of five-phase windings for a salient-pole corresponding to a k-th phase (k=0, 1, 2, 3 and 4) is supplied with a current I.sub.k. This winding current is obtained by pulse width modulating an output of a constant current converter by an output signal of a pulse width modulation pattern generator and supplying the modulated current to each of the windings as an output of an inverter. A power circuit of the inverter is simplified greatly.
