Abstract:
An alternator, comprising:a stator having a stator core in which a plurality of slots are formed on an inner periphery thereof by teeth extending in an axial direction, and first and second three-phase stator windings installed in the slots; a rotor rotatably provided inside the stator and having a field winding that generates magnetic flux by passing an electric current, and a pole core which covers the field winding and has a plurality of claw-shaped magnetic poles; and a number of the slots being two per pole per phase; wherein distances between adjacent centerlines extending in a radial direction of openings of the slots are irregularly formed, and a first three-phase stator winding and a second three-phase stator winding are wound around the stator core with a phase difference of an electrical angle of 31 to 34 degrees.
