Abstract

PURPOSE: To improve cooling effect, by stamping out a rotor plate and fan portions as an integral member from an aluminum plate, cutting and setting up conductor portions of the rotor therefrom, and fitting and fixing them to a rotor core which is another member, thus enabling the selection of the fan shape to be arbitrary.
CONSTITUTION: A rotor plate 7 together with fan portions 12 protruding from the outer periphery thereof is stamped out from an aluminum plate, and the rotor plate is formed with radial conductor portions 10 which are cut and set up therefrom with the same pitch as the slots 8 of a rotor core 6. Silicon plates are laminated in the radial direction, and one side thereof is provided with radial slots 8 while the other side is unified by welding 9 to form the rotor core 6. The conductor portions 10 of the rotor plate 7 and the slots 8 of the core 6 are fitted and bonded together to assemble a rotor 5. Thus, the size and the torsion angle of the fan can be selected arbitrarily, so that cooling effect can be increased by realizing a sufficient quantity of wind and assembling operation can be faciliated due to the simple structure.
