ABSTRACT:
Compound magnets for motor stators have a laminated structure that includes thin, flexible magnets made from permanently magnetizable particles, such as barium ferrite, that are embedded in a flexible matrix, such as rubber. Various laminated arrangements are contemplated for producing more intense magnetic fields and thin metal spacers are used in most laminated structures to collapse the respective fields of the flexible magnetic components to increase the flux density at the resultant poles and to orient the permanent magnetic fields in the magnetic circuit of the motor. With edge polarized magnetic layers, an outwardly offset side edge arrangement for the spacers is used to among other things provide a pole piece for the motor as well as intensify the field. With facially polarized magnetic layers, the edges of the spacers are inwardly offset in the laminated structure. Various arrangements are shown to simplify construction costs and to establish focus field paths.
