ABSTRACT:
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 R2of a cylindrical portion of a Lundell-type core and an outer radius R1of 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.
