摘要: An object of the present invention is to provide an automotive alternator achieving high output by overlapping a laminated core of a stator and yoke portions of a field rotor in an axial direction, and enabling high-speed and low-speed electromagnetic noise to be reduced by prescribing dimensional relationships in the stator and the field rotor.In this automotive alternator, a ratio (R2/R1) between an outer radius R2 of a cylindrical portion of a Lundell-type core and an outer radius R1 of the Lundell-type core is set to a range from 0.50 to 0.54, and a ratio (Lc/Lp) between an axial length Lc of the laminated core and an axial length Lp of the Lundell-type core is set to a range from 0.55 to 0.70.

摘要: Slots are formed in a stator core at a ratio of two per phase per pole and winding phase portions constituted by star-shaped winding units are installed in the stator core so as to line up in six layers radially. An a-phase winding phase portion, a b-phase winding phase portion, and a c-phase winding phase portion constituting a first three-phase alternating-current winding constitute three radially-outer layers, and a d-phase winding phase portion, an e-phase winding phase portion, and an f-phase winding phase portion constituting a second three-phase alternating-current winding constitute three radially-inner layers.

摘要: Six single phase winding portions are installed in slots disposed at a ratio of two per phase per pole. Each single-phase winding portion has two wave windings formed by winding a conductor wire for a predetermined number of winds into a wave-shaped pattern composed of slot-housed portions disposed at a pitch of six slots in a circumferential direction and crossover portions linking together end portions of adjacent pairs of the slot-housed portions alternately relative to an axial direction, the wave windings being offset by six slots from each other circumferentially and installed in the slots such that the crossover portions face each other axially.
