Permanent magnet type generator

摘要

A permanent magnet type generator includes a rotor having 4n (n is a positive integer) permanent magnet poles disposed in a circumferential direction of the rotor to have circumferential gap between adjoining poles and a stator that has 3n teeth and coils wound around the teeth. The stator core includes a pair of core end plates and a laminate core disposed between the core end plates. Each core end plate has a circumferential width that relates to the gap distance at portions opposite the permanent magnet poles.
