Abstract

PURPOSE:To reduce the stray-load loss of a squirrel-cage rotor by coating heat resistant paint on the inner wall of a slot and one side surface of a rotor iron plate one by one, and laminating the plates, thereby reinforcing insulators between laminated cores. CONSTITUTION:An axial hole and a plurality of slots 3 for casting secondary conductors are respectively punched at the center of a rotor iron plate and at the outer periphery for a rotary electric machine, insulating paints are coated on the one side surface 13 of the rotor ion plate and on the inner wall 3c of the slot, are heated and cured, thereby forming insulating films 7a, 7b. Then, insulating films 7a of the one side surfaces 13 of the rotor ion plates are so laminated as to align on the surfaces in the same direction, and are die cast to a rotor laminated core in such a manner that the slots are skewed and laminated in the prescribed size. In this manner, the insulators between the rotor laminated cores can be improved, thereby reducing the stray-load loss and stray-torque of the rotor.
