Abstract: According to the invention, a tandem alternator includes a rotary shaft, a first and a second power generation unit that are arranged in tandem in the axial direction of the rotary shaft, a housing, a slip ring-brush mechanism provided around a rear end portion of the rotary shaft, and a first and a second rectifier that are respectively fixed to a front and a rear end face of the housing, and a controller. The controller is electrically connected between the first rectifier and the slip ring-brush mechanism to control, at least, supply of the first field current to the first field winding. The controller is configured to form a freewheeling circuit when the first field current is interrupted. The controller is fixed to the rear end face of the housing to minimize the distance from the controller to the slip ring-brush mechanism, thereby minimizing resistance loss of the freewheeling circuit.

Abstract: In a tandem AC generator for a vehicle having dual armature core-Lundel type field core pairs placed in series, an intermediate ring as a cylindrical spacer is placed between the dual armature cores. One armature core, the intermediate ring, and the other armature core are pressed and tightly fastened to each other in the direction of a rotary shaft by front and rear housings by a through bolt. A circumference wall part of the front housing accommodates one armature core and the intermediate ring completely and further accommodates a part of an outer circumference surface of the other armature core. This simple construction of the tandem AC generator provides improved and superior vibration proof.

Abstract: A tandem vehicle alternator has dual electrical power generation units. Each generation unit has a Lundel type rotor core and a stator coil. The Lundel type rotor cores are arranged in a tandem arrangement in the vehicle alternator. Each stator coil is composed of sequential segment joining type stator coils. A center position of an inside disk part in a pair of disk parts, placed at the outside of the rotor core, is positioned within a width of an armature iron core as a stator core. This configuration enlarges a gap between inner coil ends faced to each other in the adjacent stator coils at the inside in the axis direction, cools those inner coil ends, and reduces a mutual inductance generated between the inner coil ends. The feature improves the output of the vehicle alternator and enhances the independent control of each generation unit.

Abstract: A tandem rotary electric machine for vehicles is equipped with a primary rotary electric machine and a secondary rotary electric machine arranged in tandem mechanism, namely, of a dual stator-rotor pair mechanism. In the tandem rotary electric machine, a connection lead wire connects a stator coil wound on a stator core of the primary stator-rotor pair to a rectifier device through one of accommodation parts formed in slots of the stator core of the secondary stator-rotor pair. This structure reduces the entire size or volume of the tandem rotary electric machine and increases the mechanical safety against the impact or force from outside.
