Title:
ROTOR CORE FOR MOTOR
Document Type and Number:
Japanese Patent JPS5833944
Kind Code:
A
Abstract:
PURPOSE:To enable to arbitrarily obtain right and left and rightward and leftward skews of adjacent iron plates with a single core by providing a punched part which has circumferential gaps corresponding to the skews of the adjacent iron plates and radial gaps for obtaining adequate margin for semi-punched projections. CONSTITUTION:A plurality of iron plate laminated layer holding circular-arc- shaped semi-punched projections 4 are formed around an axial hole 1 between the hole 1 and slot forming punched part 2 of a circular iron plate, a punched part 5 which has circumferential gaps corresponding to the skews of the at least adjacent iron plates to communicate with both ends of the projection 4 and radial gaps for obtaining adequate margin for the projection 4 is provided, the iron plate is displaced so that many semi-punched parts are superposed in the same direction, are sequentially displaced in the circumferential direction to be overlapped with the part 5, and are press-fitted, thereby holding the laminated state.
