Abstract
A method for manufacturing an electric winding of an electromagnetic induction apparatus includes providing a conductor structure including a conductor element extending longitudinally along a main extension direction and one or more spacer tapes of electrically insulating material around said conductor element along said main extension direction, each spacer tape having spacer portions at corresponding lateral surfaces of said conductor element and spaced one from another along the lateral surfaces. The method includes forming an electric winding extending axially along a winding direction and having a plurality of turns arranged around said winding direction where each turn is formed by a corresponding longitudinal portion of said conductor element. The spacer portions are interposed between adjacent turns at opposite sides and respectively positioned spaced one from another to define an empty space to form a radial channel of the electric winding and configured for a passage of an electrically insulating medium.
