Abstract

PURPOSE:To enable rotating parts to rotate at high speed, by forming. an amorphous magnetic material on the surface of perforated discshaped soft magnetic rotating parts to constitute a laminated rotor core fixed with multiple sheets put one upon another around a body of rotation. CONSTITUTION:Multiple perforated disc-shaped soft magnetic rotating parts 12 are fitted into around small diameter section 10b and clamped between a collar 13 and a shoulder section 10c fixed by forcibly fitting to the small diameter section 10b. A laminated rotor core 11 is composed of these soft magnetic rotating parts 12. The base 12a of the soft magnetic rotating parts 12 is made of a perforated discshaped silicon steel plate, over all the surface on both sides of which thinner perforated disc-shaped amorphous magnetic material layer 12b is formed. The magnetic characteristic and tensile strength of overall rotating parts can thereby be so improved that the body of rotation can be rotated at high speed.
