Patent number: 6707225Abstract: A method for improving the efficiency of electromagnetic devices having a ferromagnetic core containing electrical windings. The ferromagnetic core is variously configured to include intra-turn ferromagnetic protrusions which are configured to nestle between junctions of the windings, such as in the bends, to increase the amount of ferromagnetic material retained proximal the windings. The increased amount of ferromagnetic material increases electromagnetic efficiency, and reduces the probability that the wiring will be nicked on the edges of the electromagnetic core. By way of example, the intra-turn ferromagnetic projections may be formed within an integrated electromagnetic core, as unitary core extensions, or as singular protrusions attached to the electromagnetic core.Type: GrantFiled: February 26, 2001Date of Patent: March 16, 2004Assignee: Delco Remy International, Inc.Inventor: Michael Duane Bradfield
