Title:
MAGNETIC INDUCTION MOTOR AND PRODUCTION METHOD FOR SAME
Document Type and Number:
WIPO Patent Application WO/2015/098159
Kind Code:
A1
Abstract:
The present invention is a magnetic induction motor that has coils wound into concentrated windings and a flange part protruding from an inner diameter end part of a permanent magnet shaft part toward both sides in the peripheral direction, and a production method for the same. A first stator core and second stator core are configured from pairs of core blocks that are configured through the spacing and overlapping in the axial direction of core blocks, which each comprise an arc-shaped core back part and a single tooth protruding radially inward from the inner circumferential surface of the core back part, and are disposed in an annular shape so that the circumferential side surfaces of the core back parts come into contact with each other. A permanent magnet is divided into and configured from a plurality of magnetic blocks that are sandwiched between the core blocks. Each magnetic block has an arc-shaped base part, a single shaft part protruding radially inward from the inner circumferential surface of the base part, and a flange part protruding from the inner diameter end part of the shaft part toward both sides in the peripheral direction. The base parts and shaft parts are positioned within core block pairs, and the flange portions protrude from the core block pairs in the peripheral direction.
