Abstract
An alternator includes a rotor including claw-shaped magnetic poles fitted onto a rotating shaft, and a cooling means disposed on an end surface of the claw-shaped magnetic poles, and a stator including a stator core disposed facing the rotor, the stator core having a plurality of slots, and a stator winding installed in the stator core, the stator being cooled by the cooling means, and a bracket for supporting the rotor and the stator, a passage for an air flow generated by the cooling means being disposed inside the bracket, the stator winding including coil ends extending outwards from end surfaces of the stator core, and a shielding material being disposed so as to cover at least an inner circumferential surface of the coil ends.

An alternator comprising:
- a rotor comprising:
- claw-shaped magnetic poles fitted onto a rotating shaft;
- and
- a cooling means disposed on said claw-shaped magnetic poles;
- and a stator comprising:
- a stator core disposed facing said rotor, said stator core having a plurality of slots;
- and
- a stator winding installed in said stator core, said stator being cooled by said cooling means;
- and
- a bracket for supporting said rotor and said stator,
- a passage for a cooling air flow generated by said cooling means being disposed inside said bracket,
- said stator winding comprising coil ends extending outwards from end surfaces of said stator core, and
- a shielding material being disposed so as to cover at least an inner circumferential surface of said coil ends, wherein at least one of a part of an outer circumferential surface of said coil ends and a part of an outer axial end surface of said coil ends is not covered by said shielding material.
