<p>PROBLEM TO BE SOLVED: To provide a control method, for an AC generator for an automobile, in which the output of the AC generator for the automobile is enhanced, in which a field winding current is reduced and in which a copper loss generated in a field winding can be reduced. SOLUTION: A pulley is arranged at one end of a shaft, and a slip ring 10 is arranged at the other end. A brush 11 is attached to the slip ring 10 so as to be slidable, and electric power is supplied to a field winding 4 which is wound on a yoke arranged at the inside of a rotor 2. Built-in fans which can obtain a quantity of airflow proportional to the speed of the rotor 2 are installed at the right and the left of the rotor 2. A claw-shaped magnetic pole 3 is arranged at the outer circumferential part of the rotor 2, a stator 7 is arranged by keeping a slight gap from the outer circumferential part, a stator core 8 is installed at the stator 7, and a stator winding 9 is wound on the stator core 8.</p> |
