发明名称	Method of manufacturing laminations for electrical apparatus
摘要	A method of manufacturing a stator lamination for a dynamoelectric machine. A length of steel wire is formed into alternate straight and undulated portions and is formed into a coil such that the inner turn of the coil coprresponds to the undulated portion and the outer turn corresponds to the straight portion of the wire. The coil of wire is placed in a die cavity of a die that has a configuration corresponding to a stator lamination. The loops of the undulated portion are placed in radially extending grooves of the die cavity and the outer turns of the coil are placed in an annular groove of the die cavity. The die and a punch are utilized to coin the wire to the shape of the die cavity.
