Lead-wire arrangement of vehicle AC generator
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.
As the number of holes increases, the wall becomes more uneven, thereby causing a loud fan noise. Moreover, because the number of insulators to be inserted into the holes increases, the production cost increases.
A main object of the brushless alternator is to provide an improved lead-wire arrangement of an ac alternator for a vehicle.
Another object of the invention is to provide an ac generator which has an inexpensive structure for suppressing a fan noise.
According to a preferred embodiment of the ac generators, a brushless ac generator including a stator having a multi-phase stator winding, a rectifier unit, a frame having a wall supporting the stator at one side thereof and the rectifier unit at the other side. The wall has a minimal number of lead-wire-holes for the output lead wires. Terminal members may be disposed in the lead-wire-holes for holding the output lead wires.
In the foregoing description of the present ac generator, the invention has been disclosed with reference to specific embodiments thereof. It will, however, be evident that various modifications and changes may be made to the specific embodiments of the present invention without departing from the broader spirit and scope of the invention as set forth in the appended claims. Accordingly, the description of the present invention in this document is to be regarded in an illustrative, rather than restrictive, sense.
