Vehicular alternator and method of producing the same |
摘要 |
In a vehicular alternator having a permanent magnet protection mechanism, each magnet holder of a non-magnetic characteristic if a rectangle prism shape accommodates each permanent magnet disposed between adjacent claw poles. The magnet holders are connected in a ring shape along a circumferential direction of the alternator by using each connecting plate part which extends from each magnet holder in approximate circumferential direction toward an inner side of and at a front tip part of each claw pole. The connecting plate parts and the magnet holders are made from a non-magnetic plate by cutting and bending. Making the surfaces and the connecting plate part of each magnet holder from the non-magnetic plate by cutting and bending provides a high accuracy magnet position in the alternator with low manufacturing cost.
