AC GENERATOR FOR A VEHICLE

摘要

An alternating current(A.C.) generator for vehicles is provided to improve a cooling efficiency. The A.C. generator comprises an electric rotor(3), a cooling fans(4a,4b) formed at both sides of the electric rotor(3), a pair of braket for supporting the rotor(3), and a brush holder having a diode and a voltage adjusting apparatus. A guide groove is formed at paths which can draw out a lead line(10a) for the cooling efficiency of the generator. The outlet angle of a blade(4b-1) has about 70 degrees and a number of the blade(4b) are sixteen sheets. Thereby, it is possible to improve the cooling efficiency.
