Title:
CORE ASSEMBLY FOR SMALL-SIZED MOTOR
Document Type and Number:
Japanese Patent JPH08214477
Kind Code:
A
Abstract:
PURPOSE: To provide a core assembly for small-sized motor which can reduce the magnetic directivity derived from the rolling direction even when the core assembly is made of a nonoriented electromagnetic rolled plate or oriented electromagnetic rolled plate.
CONSTITUTION: A laminated core 12 formed by laminating a plurality of core pieces having the same magnetic directivity is provided between a pair of magnetism collecting cores having flanges 18 which are plastically worked so as to extend the flanges 18 in the axial direction. The magnetism collecting cores 11 and 13 and laminated core 12 are arranged so that their magnetic directivity can be shifted from each other.
