Abstract
PURPOSE: To shield the most of magnetic fluxes leaked from the gap between the windings and to reduce the magentic fluxes which will be returned through the iron core legs by installing endless magnetic shield plates at the ends of winding.
CONSTITUTION: All of the end portions of windings 9 and 9A are covered by magnetic shielding plates 14. Since magnetic fluxes leaked from the gap between inner and outer windings are shielded by the magnetic shield plates 14, the magnetic fluxes, which will enter into the structure such as core tightening metals 5 and 4, and a linking metal 6 which are arranged at the top and bottom sides of the magnetic shield plates 14, are almost completely eliminated. Since the magnetic fluxes which have entered into the magnetic shield plates 14 have no returning circuit formed by core legs 1, the loss in the core legs can be reduced.
