    Abstract: An alternator for use in an automotive vehicle includes a circuit for detecting initiation of rotation of an engine. Upon detecting the initiation of rotation, excitation current supply to a field winding is started, and thereafter an alternator output is controlled by controlling the excitation current. A resistor is connected to one phase winding of an armature to obtain a voltage indicating initiation of rotation during a period in which no excitation current is supplied to the field winding, and a capacitor is connected to another phase winding to raise the indicating voltage level. Since the indicating voltage induced by a small amount of residual magnetism is increased to a sufficient level by the capacitor, the initiation of rotation can be accurately detected.

The yoke portion (72) extends from the cylindrical portion (71) in a radially outward direction. The claw-like magnetic pole portion (72) is connected to the yoke portion (72), and is formed so as to surround the field coil. The stator includes a multiple-layer iron core (32). A ratio of an axial-direction length L1 of the multiple-layer iron core (32) to an axial-direction length L2 of the cylindrical portion (71) of the Lundel-type iron core is in a range of 1.25 to 1.75. A ratio of an outside diameter R2 of the cylindrical portion (71) of the Lundel-type iron core to an outside diameter R1 of the claw-like magnetic pole portion (73) of the Lundel-type iron core is in a range of 0.54 to 0.60.

    Abstract: It is an object of this invention to provide an alternator for a vehicle in which all electric conductors forming bridge portions are sufficiently exposed to cooling winds so that the cooling performance is remarkably improved. It is another object of this invention to provide an alternator for a vehicle which is excellent in cooling performance, insulating characteristic, and heat resisting property. An alternator for a vehicle includes a stator. The stator includes an iron core 22, an electric conductor 21, and an insulator 23. The electric conductor 21 forms a winding on the iron core 22. The insulator 23 provides electric insulation between the electric conductor 21 and the iron core 22. The stator is supported by a housing. The dimension of openings of slots in the iron core 22 is smaller than the distance between inner side surfaces of the slots. The electric conductor 21 has accommodated portions accommodated in the slots, and bridge portions connecting the accommodated portions. Pieces of the electric conductor which extend out of the slots are approximately separated into a conductor groups 21f located on outer radial sides of the slots and a conductor group 21g located on inner radial sides of the slots, and form the bridge portions. Predetermined gaps are provided between pieces of the electric conductor in the bridge portions. The bridge portions have ridge portions inclined in a same circumferential direction in each of the outer radial side and the inner radial side, and top portions connecting the ridge portions along an axial and radial direction.

    Abstract: The present invention provides a compact, efficient and noiseless alternator for an automotive vehicle which employs a double-layer coil arrangement in a slot for eliminating coil end interference as well as improving the space factor. An automotive alternator comprises a Lundel-type core rotor with 16 poles, and a stator with toothed portions of 96 poles spaced by slots. U-shaped conductor segments are installed in the slots. One portion of the conductor is accommodated in an outer layer portion of a predetermined slot, while the other portion is accommodated in an inner layer portion of a slot phase shifted by an electric angle of 180.degree.. In this manner, all of the slots are separated into the inner and outer layers to accommodate a plurality of conductor segments. These conductor segments are connected only at one side of the stator to form a total of twelve wavy winding coils. These twelve wavy winding coils are divided into three groups each consisting of a serial connection of four wavy windings to constitute one phase of a three-phase stator coil.
