ABSTRACT:
A stator for an automotive alternator is provided with good installation characteristics for stator coils and which can lower noise. The stator includes a stator core in which a plurality of slots are formed at an inner circumference thereof and stator coils which are fitted into the slots. A rotor is provided inside the stator and includes a rotor coil, and a pole core for housing the rotor coil. Two slots are provided for each set of stator coils, each phase and each magnetic pole and the total number of slots is seventy-two or more. The stator core formed by laminating a plurality of sheet-shaped magnetic members. The stator coils are disposed in the slots, and the stator core is rounded such that the stator coils become the inner side thereof and both end surfaces thereof are contacted to connect the stator core in an annular shape.
