PURPOSE:To improve the efficiency of a rotary electric machine and to reduce the weight of the machine by forming slots facing the inner and outer peripheries of a core back of a stator core and winding stator coil on the core back, thereby shortening the stator coil and a magnetic circuit of teeth part. CONSTITUTION:The first and second slots 41, 42 are respectively formed at the positions facing the inner and outer peripheries of a core back of a stator core 1, and a stator coil 2 is wound on the core back 12 through the first and second slots 41, 42 divided via the core back 12. In this manner, the length of the coil 2 is shortened, and the magnetic circuit of the teeth part 11 of the core 1 is shortened. |
