Abstract
A presently-preferred process for manufacturing a magnetic-induction device comprises stacking a plurality of laminae to form a winding leg, a first yoke, and a second yoke, and fixedly coupling a first end of the winding leg to the first yoke. The presently-preferred process also comprises winding a length of insulated conductive cabling on the winding leg to form a phase winding after fixedly coupling the winding leg to the first yoke, and fixedly coupling a second end of the winding leg to the second yoke after forming the phase winding. Alternatively, the length of insulated conductive cabling may be wound on the winding leg after the second end of the winding leg has been fixedly coupled to the second yoke.
