    Abstract: In an on-vehicle alternator, both the magnetic flux variation frequency and maximum flux density are decreased sufficiently to thereby decrease the internal iron loss and thereby realize an increase in the current generation efficiency. The on-vehicle alternator comprises a rotor wherein magnetic pole cores that are polarized by a rotor coil to alternately different polarities are circumferentially disposed on the outer periphery thereof at prescribed equi-angular intervals. A permanent magnet which is embedded within a resin-made retainer body is provided between the magnetic pole cores and has side faces, as viewed circumferentially, which are polarized respectively to the same polarities as those of adjacent respective magnetic pole cores to thereby vary the magnetic flux quantity directed toward stator coils so as to exhibit a circumferential gentle curve. A rectifier is constructed using SiC-MOS transistors so that it is conductive and operative to thereby charge a battery with the current developed in the stator coils only when the alternating current voltages generated in the stator coils have become higher than the battery voltage.

    Abstract: To directly mount a generator to an engine block without causing overheating of the generator or a rectifier, a voltage regulator incorporates a rectifier which employs monocrystalline silicon carbide (SIC) MOS power transistors as semiconductor rectifying devices. This voltage regulator is fixed to housings of a generator, and the housings of the generator are directly mounted to an engine block. In this construction, it is possible to prevent overheating of the rectifier in the voltage regulator as well as of armature windings and a field coil of the generator regardless of an increase in the amount of heat transferred to the generator due to direct mounting.

    Abstract: Cooling wind is introduced into an electric-parts-chamber through openings formed at the bottom of a cover, then taken into the intake side of a cooling fan through the air intakes formed in the wall end of a housing from the electric-parts-chamber. The cooling wind is accelerated by the fan to be driven off from the outlets formed in the peripheral wall of the housing. The cylindrical portion of the positive side cooling fins of the rectifier is extended to the space between the outer periphery of the fan and the outlets. The inner diameter of the cylindrical portion is longer than that of the rear coil end. Thus, the coil end and the cylindrical portion of the positive side cooling fin are cooled sufficiently by the cooling wind blowing thereon at high speed, so that the rectifier can endure large thermal load with reduced wind noise even if the size of the alternator is small.

    Abstract: A power supply system has a three-phase alternating current generator, a storage battery, and a three-phase rectifying device connected between the alternating current generator and the storage battery. The rectifying device includes three SiC-MOSFETS which are turned on when the corresponding alternating voltage is positive and turned off when the corresponding alternating voltage is negative. A duty control device switches each of the three SiC-MOSFETS on and off according to a selected duty ratio so that the alternating current generator can generate an optimum voltage in proportion to a rotational speed of a rotor of the alternating current generator.

    Abstract: A stator which may be employed in an electric rotating machine. The stator includes a stator winding which includes in-slot portions disposed in slots of a stator core. The in-slot portions are arrayed in each of the slots in a form of multiple layers aligned in a radial direction of the stator core. The stator winding is made up of a first winding and a second winding which are connected together through a joint. The first winding is defined by a portion of the stator winding between the joint and an end of the stator winding which is to be connected to an external. The second winding includes the in-slot portion placed within at least one of the slots as an outermost layer that is one of the layers placed most outwardly in the radial direction of the stator core. This results in a great decrease in leakage current.

    Abstract: 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.
