    Abstract: An alternator disposed in the engine compartment of a vehicle is composed of a rotor having magnetic poles and a field coil, a cooling fan member, a stator disposed around the rotor and having a stator core and a multi-phase stator winding. The multi-phase stator winding has a plurality of conductor segments each having a U-turn portion to form a first coil-end group and a pair of joint portions to form a second coil-end group. The first coil-end group is disposed where temperature is higher than the other end, and the second coil-end group is disposed on the other end. The cooling fan member sends less cooling air to the second coil-end group than the first coil-end group.

    Abstract: The present invention prevents the degradation of the power generating efficiency of an alternating current generator by preventing the expansion of an air gap formed between pole cores and a stator core, achieves low-noise operation by preventing generation of high-frequency impact magnetic noise, and makes it possible to relieve strains applied on a magnet holder. The present invention utilizes sixteen magnets, each of which fits between two of sixteen claw-like magnetic poles formed on the outer periphery of Lundell-type pole cores, which rotates integrally with a shaft. The magnets are caught and stopped by a magnet holder which has been formed by interconnecting zig-zagging segments and has elasticity as a whole. Here, the permanent magnets are held by the magnet holder so that the magnet holder does not protrude towards the rotor side from the outer peripheral face of the Lundell-type pole cores and the contacting faces of the magnet holder contact the outer faces of the permanent magnets. The claw-like magnetic poles are disposed so as to face the stator.

    Abstract: A generating apparatus includes a generator, a first and a second rectifiers, and a voltage regulator. The generator has three-phase star-connected armature windings which generate three-phase high-output voltage at phase-terminals and low-output voltage at a neutral point. The first rectifier is a three-phase full-wave rectifier connected between the phase-winding and a high-voltage load, and the second rectifier is a diode connected between the neutral point and a low-voltage load with a battery. The regulator regulates the high output voltage to energize the high-voltage load and, at the same time, the low-output voltage to become an optimum voltage level for charging battery. MOSFETs may be used for the first rectifier to short-circuit the armature windings thereby supplying them with leading currents which are respectively ahead of the high-output voltages, so as to increase the generator output power.

    Abstract: An alternating current generator for a motor vehicle includes magnet type field cores, i.e., field cores with claw poles on which permanent magnets are interposed in the spaces between the claw poles, where the generator has a ratio of number of claw poles/outside diameter of the field core that allows generation of a large output current. The alternating current generator includes permanent magnets disposed in spaces between peripherally adjacent claws which reduce the magnetic flux leakage caused by the field coil occurring in the spaces. When a residual magnetic flux density higher than 0.25 tesla is applied in advance in a direction that reduces magnetic flux, a large output current is obtained when the above-noted ratio is in the range of from about 1.6.times.10.sup.-1 to 2.0.times.10.sup.-1 (1/mm).

    Abstract: An alternating current generator having a first Y-form three-phase connecting circuit including three first windings connected with each other in a Y-form, a first rectifying circuit for rectifying currents output from output terminals of the three first windings, a second Y-form three-phase connecting circuit including three second windings connected with each other in a Y-form, and a second rectifying circuit for rectifying currents outputted from output terminals of the three second windings. The three first windings are inserted in slots of a stator core so that the three first windings have phase differences of approximately 120 degrees from each other. Each of the three second windings is divided into first and second winding portions which are inserted in separate slots of the stator core, in which the three first windings are inserted so that resultant output vectors of the respective two divided windings have respective phase differences of approximately 30 degrees with respect to output vectors of the respective three first windings. By virtue of the above-mentioned structure, the number of slots in the stator core is reduced, the ripple contained in a resultant output waveform is decreased by adding together output currents of the first and second rectifying circuits, respectively, and heat generation due to a circulating current flowing in the connecting circuits can be prevented by avoiding the use of a delta-form three-phase connecting circuit.

    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.
