A rotary electric machine has a brush assembly that defines a slip ring cavity enclosing slip rings and brushes. The brush assembly provides two different outlets for particles and cooling air. The first outlet is located on a side with respect to a shaft and is directed in an axial backward direction. The second outlet is located on a bottom and is directed in a radial downward direction. The second outlet is close to a fan for inducing airflow in the slip ring cavity.

In a regulator (voltage control apparatus), an IC chip is adhered to the surface of a first metal plate. A lead wire connects the IC chip with an outside connecting terminal. A second metal plate formed to cover the IC chip is formed integrally with a negative side wiring for supplying a battery voltage into the IC chip.

In an engine auxiliary unit driving equipment for transmitting an engine driving force from a crank pulley to a plurality of engine auxiliary units including an alternator, a driven poly-V pulley provided at least in the alternator has a plurality of grooves extending in a circumferential direction. A poly-V belt, which has a plurality of projections extending in a longitudinal direction so as to correspond to the grooves of the driven poly-V pulley, bridges between the crank pulley and the driven poly-V pulley. The poly-V belt is substantially divided in an axial direction of the driven poly-V pulley into two pieces each having plural pieces of the projections. Accordingly, a tensile strength acting in a width direction of the poly-V belt is substantially divided midway between the divided poly-V belts so that cracks in the round poly-V belt hardly occurs, resulting in securing a longer lifetime of the poly-V belt. Further, a natural frequency of the poly-V belt around the alternator maybe shifted to restrict a belt flapping increase due to resonance at an idling time when a revolution fluctuation is larger.

A rectifier unit of a vehicle AC generator is comprised of a plurality of metal cases, a plurality of pairs of first and second semiconductor chips and a plurality of pairs of first and second lead wires. The first lead wires are respectively connected to the first semiconductor chips, and the second lead wires are connected to the second semiconductor chips. Each pair of first and second semiconductor chips is disposed in one of the metal cases. The first lead wires are connected to each other to form a first rectifying circuit and second lead wires are connected to form a second rectifying circuit. Therefore, the number of parts for connecting the rectifier circuits can be reduced without providing complicated insulator arrangement.

An electric-machine rotor is composed of a field coil, a pair of pole cores having a plurality of claw poles to enclose the field coil, a plurality of auxiliary permanent magnets disposed between the claw poles, a shaft fixed to the pair of pole cores, and a pair of slip rings connected to the field coil. The rotor is provided with a pattern on a surface of the pole cores for indicating the polarity of the claw poles when the field coil is energized.

In an a.c. generator for vehicles, an output terminal connected to a rectifier circuit unit has a seat surface on which an electric cable for connection with a storage battery is seated. The seat surface is positioned outside a rear cover and an insulating member in the longitudinal direction of the output terminal. The electric cable is tightened to the seat surface by a nut engaged with the output terminal, while holding the electric cable from contacting the insulating member. Thus, the insulating member is restricted from being deformed and the nut is restricted from loosening even when the insulating member contracts.
