摘要： An improved construction of Randel-type rotor of a vehicle-mounted alternator, capable of reducing the windage noise which is produced as a result of interference between the rotor and the stator of the alternator. The rotor has a pair of pole cores provided with a plurality of mutually meshing claws, and an exciting coil disposed at the inner side of the pole cores. Spacers in the form of an integral ring or discrete wedges are fitted in the spaces between adjacent pole core claws so as to provide a substantially smooth cylindrical outer peripheral surface of the rotor portion facing the radial teeth on the stator.

摘要： A brush holding device for holding carbon brushes in sliding contact with slip rings of an alternator. The device has a brush holder formed by an insertion molding integrally with terminal plates. The brush holder has a pair of brush chambers for movably receiving the carbon brushes and a pair of pig tail chambers accommodating pig tails through which the carbon brushes are electrically connected to the terminal plates. The carbon brushes are resiliently biased into contact with the slip rings by means of coiled springs acting between the radially outer ends of the carbon brushes and the radially outer walls of the brush receiving chambers. The pig tails are extended into adjacent brush chambers through slits formed in the walls separating the pig tail chambers from associated brush chambers and are connected to the carbon brushes at lateral sides of the latter.

摘要： When an engine key switch of a vehicle is closed, a rotor coil of a three-phase a.c. alternator adapted to charge a vehicle-mounted battery is excited by a first controlling circuit. Even with the closure of the engine key switch, the exciting current is restricted to a predetermined value by a second controlling circuit before the alternator has reached a predetermined operating state. The operating state of the alternator is monitored by detecting a voltage at the neutral point of a stator coil connected in star of the alternator.

摘要： A semi-conductor voltage regulation system for a vehicle includes engine rise-up detection circuit and an oscillator circuit. The field exciting current is intermittently supplied by the oscillator circuit before the engine starts and continuously supplied after the engine has started so as to minimize battery discharge. The engine rise-up detection circuit changes its input impedance in accordance with the voltage applied thereto, whereby a highly reliable regulator with less heat generation may be obtained.
