Abstract
PURPOSE:To reduce locally heating an iron core and by providing the outer side of an end if a stator iron core with an amorphous magnetic material. CONSTITUTION:The outer side of an axial end of a stator iron core 1 is laminated with sheets of an amorphous magnetic material of an Fe-B system with high electric resistance and high concentration of magnetic flux, whereof a required number is cut into strips and adhered with adhesives, and provided with a block solidified together with a duct piece 15, the back of said amorphous magnetic material is matched with a silicon steel plate ring 14 to be fixed and held with claming metal fittings through an end duct 2 and a cross arm plate 3 of the iron core. Thereby an eddy current induced by the magnetic flux vertically inciding on the surface of the amorphous magnetic material 13 is reduced to less than about 1/3 thus reducing the local temperature rising because the electric resistance of the amorphous magnetic material is more than three times of that of the silicon steel plate.
