摘要： According to the invention, a tandem alternator includes a rotary shaft, a first and a second field arranged in tandem on the rotary shaft, and a first and a second armature arranged in tandem in the axial direction of the rotary shaft. The first armature is provided on an outer periphery of the first field to constitute a first power generation unit. The second armature is provided on an outer periphery of the second field to constitute a second power generation unit. The first and second fields are arranged to abut each other in the axial direction of the rotary shaft, so as to minimize the axial length of the alternator. The first and second fields are configured to respectively create a first and a second magnetomotive force whose directions are opposite to each other, so as to minimize magnetic leakage between the first and second power generation units.

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.

摘要： A stator for a multiple-phase rotary electric machine provided a stator core with slots and a coil formed of a plurality of windings for individual phases. Each winding has slot-accommodated portions held in different slots, turn portions connecting the slot-accommodated portions outside of the slots in an axial direction, and a return portion that connects two of the turn portions and changes a winding direction of the winding at given slots. The turn portions include specific turn portions which are the same in a circumferential position as the turn portion connected to the one of the return portion. The specific turn portions are located, in a radial direction, to be drawn apart from the rotor than the slot-accommodated portions connected to the specific turn portions.
