FIELD: electricity.
SUBSTANCE: core manufacturing method consists in manufacture of packs of pieces of amorphous belts, formation of shaped outline of packs by winding on mandrel with further thermal and mechanical processing of packs, including vacuum treatment by binding agent and cutting of certain part from each pack with further assembly of core in cylindrical mandrel. At formation of packs, triangular mandrel, the axis of which is oriented parallel to axis of electric machine, is used. Cutting of some part of the pack is performed parallel to mandrel axis. As cylindrical mandrel, housing of electric machine is used, in which there layer by layer are laid packs so that layers of packs are located in axial direction of that housing. Packs in each layer are fixed on side surfaces.
EFFECT: easier manufacture and lower manufacturing labour intensity, noise level and vibrations of electric machine.
