ABSTRACT:
A laminated electromagnetic core and a method of manufacturing incorporates a double layer winding with the core being formed from first and second sets of apertured laminations of which one set accommodates the conductors of one layer of the winding and the other set accommodates the conductors of the other layer of the winding the conductors being interconnected by end windings and adjacent laminations in each lamination set are displaced from mutual alignment to permit the conductor end windings to be of minimal length such that conductor ends which are to be interconnected adjoin one another, thereby facilitating the formation of end windings by in situ casting.
