ABSTRACT:
A method for fitting magnetic wedges which comprises steps of passing a current through a stator winding on a stator core of an electric rotary machine to produce magnetic flux passing through slot openings, successively forcing the magnetic wedges in the slot openings while keeping the winding energized to maintain the magnetic wedges in predetermined positions in the slot openings, and impregnating varnish into the stator core with the slot openings fitted with the magnetic wedges and with the stator winding kept energized, and an apparatus for embodying the method.
