Abstract

Abstract DYNAMOELECTRIC MACHINE STATOR HAVING ARTICULATED AMORPHOUS METAL COMPONENTS ABSTRACT OF THE DISCLOSURE A dynamoelectric machine stator is formed of an amorphous metal yoke or back iron portion, consisting of either a spirally wound coil of amorphous metal ribbon or an edge-wound helix of such ribbon in which the respective turns are stacked together to define a cylinder, in combination with a plurality of separately formed amorphous metal teeth that are mounted at spaced intervals on the interior surface of the yoke to define a plurality of spaced winding-receiving slots that each extend axially between pairs of the teeth. The teeth are each secured in operation position on the yoke by being both bonded directly to it and by the supporting relationship established between the teeth and abutting slot liners, energizing windings and a cured insulating coating which is applied to the stator after the energizing winding is positioned in the stator winding slots. In various disclosed embodiments of the invention a number of different tooth configurations and back iron arrangements are disclosed in combination with different arrangements of slot liners and energizing winding supports for holding the teeth in their respective fixed positions on the stator yoke.
