ABSTRACT:
A separator for accurate positioning and easy replacement of magnets in an annular array around a spindle comprises an annularly shaped, elastic separator constructed of plastic materials. The plastic separator includes either cross machine struts that define open bottom recesses or it includes closed bottom recesses for receiving and accurately positioning and retaining the magnets circumferentially around its annular body. The separator applies an initial stress to the magnets to assure precise positioning. Radially directed projections on the body of the separator are shaped to fit into a groove defined in the interior of a motor housing, whereby the magnets carried by the separator are precisely located relative to the motor housing. The Separator-based magnet fixing means are particularly suitable for disk storage spindle applications.
