Abstract

1,009,827. Rotor core constructions. SANYO ELECTRIC CO. Ltd. Oct. 9, 1963, No. 39798/63. Heading H2A. A dynamo-electric machine rotor constructed to withstand centrifugal force comprises a shaft 4 extending through an axial bore 3 in a cylindrical ferrite core 1 which is permanently magnetized about its periphery 2 in alternately opposite polarities, and two centrally apertured retainer discs 6 fitted over the shaft in face-toface relationship with the adjacent core end faces, the components being joined together to form an integral assembly by a single continuous adhesive layer 9 which extends between opposed faces of the core, shaft and discs. The discs may be non-magnetic and have a central boss which is forced over a knurled portion 5 of the shaft, and the layer 9 may be an epoxy resin.
