Title:
界磁巻線型回転電機
Document Type and Number:
Japanese Patent JP7095532
Kind Code:
B2
Abstract:
A field coil type rotating electric machine includes a stator and a rotor. The stator includes a stator core, stator teeth arranged in a circumferential direction and each radially protruding from the stator core, and a stator coil wound on the stator teeth. The rotor includes a rotor core, main poles arranged in the circumferential direction and each radially protruding from the rotor core, and a field coil wound on the main poles. Each of the stator teeth and the main poles extends in an axial direction. Each of the main poles has a pair of main-pole end portions located respectively at circumferential ends of the main pole and both radially facing the stator. For each of the main poles, in at least one of the main-pole end portions of the main pole, there is formed at least one cut for part of an axial length of the main pole.
