Ac generator for vehicle
专利汇可以提供Ac generator for vehicle专利检索，专利查询，专利分析的服务。并且PURPOSE:To reduce the generation of magnetic uncomfortable noise due to the third higher harmonic, by connecting diodes between the neutral point of a three-phase star armature winding and positive and negative DC output ends, and by providing chamfers at the outer peripheral corner sections of click type magnetic poles. CONSTITUTION:On an AC generator for a car body which is provided with a pole core having click type magnetic poles 2 and with a three-phase star armature winding 4, chamfers 2b are provided at the circumference-directional corner sections of the outer peripheral faces 2a of each click type magnetic pole 2. And diodes 9 are respectively connected between the neutral point N of the three-phase star armature winding 4 and positive and negative DC output ends 7, 8, and the third higher harmonic electromotive force found between the diode and the neutral point is rectified and fed. In this manner, output current by approx. rated rotational frequency can be increased, and magnetic uncomfortable noise by approx. maximum rotational frequency can be reduced.，下面是Ac generator for vehicle专利的具体信息内容。
