PURPOSE:To decrease magnetic flux leakage at each of openings of stator core slots and rotor core slots in a rotary electric machine so as to increase maximum torque thereof by equally forming the respective width of the stator core slots and the rotor core slots between the slot bottom and the opening. CONSTITUTION:A first slots 12 are provided on an inner peripheral surface of a stator core 11 with an equal spacing, and facing to the slots 12 a second slots 18 are provided at an outer peripheral surface of a stator core 17 with that equal spacing. Each width of the first and second slots are also formed substantially equal between the slot bottom and the slot opening. In this manner, the magnetic flux leakage at each of the openings of slots 12 and 18 can substantially be decreased and the flux decrease between the stator and the rotor can be minimized so that the generated torque of the rotary electric machine is increased. |
