Claims
- 1. 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.
- 2. An ac generator according to claim 1, further comprising a cooling fan fixed to one end of said rotor near said rectifier unit.
- 3. An ac generator according to claim 1, wherein said rectifier unit has a pair of bridge circuits of diodes respectively connected to said pair of stator windings.
- 4. An ac generator according to claim 1, wherein said rectifier unit comprises a common positive cooling fin and a common negative cooling fin.
- 5. The ac generator as claimed in claim 1, wherein said stator winding comprises a first star-connected three-phase winding and a second star-connected three-phase winding.
- 6. An ac generator according to claim 1, wherein each of said input terminals is positioned at an outer periphery of said rectifier unit.
- 7. An ac generator according to claim 1, wherein each of said columnar terminal members has a pair of passages for supporting two of said output lead wires, each of said passages opening toward a respective lead wire hole for allowing ease of insertion of each lead wire into a respective one of said passages.
