Abstract
An ac generator for a vehicle includes a multi-poled rotor, a stator having a multi-phase stator winding which has output lead wires, a full-wave rectifier unit, and a frame having a wall supporting the stator at one side thereof and the rectifier unit at the other side. The output lead wires are grouped to form a plurality of bundles. The wall has lead-wire-holes formed to correspond to the bundles. The rectifier unit has input terminals disposed to correspond to the bundles and respectively connected to the output lead wires.
Claims7
An ac generator for a vehicle, comprising:
- a rotor having a shaft;
- a stator having first and second three-phase stator windings, each of which has three phase-windings and three output lead wires respectively extended from said stator windings;
- a frame for supporting said rotor and said stator, said frame having three lead-wire-holes spaced apart from each other in the circumferential direction of said frame;
- and
- a rectifier unit disposed outside said frame, said rectifier unit having a plurality of diodes and a plurality of input terminals respectively connected to said output lead wires, each of said input terminals including a columnar terminal member for holding two of said output lead wires each of which is connected to different one of said diodes;
- wherein said columnar member is disposed in each of said lead-wire holes;
- and
- wherein first one of said columnar terminal members holds two of said output lead wires extended from said first stator winding, second one of said columnar terminal members holds two of said output lead wires extended from said second stator winding and the remainder of said columnar terminal members holds two of said output lead wires respectively extended from first and second stator windings.
