NOVELTY - The method involves providing an annular inductor (230) that comprises an inductor core with distributed gap material, and rotating the inductor. The inductor is wound as function of rotation of the inductor with multiple strands of a wire, and the strands of wire are electrically connected in parallel to form a winding. The inductor is placed into a container, and a cooling unit is positioned adjacent to the inductor by mounting the inductor in potting material. An additive is mixed with the potting material to form a mixture.    USE - Method for manufacturing an electrical inductor apparatus that is utilized in an application. Uses include but are not limited to variable speed drive system, uninterruptible power supply, backup power system, inverter, converter for renewable energy system, hybrid energy vehicle, tractor, crane, lorry, machinery using fuel cell, battery, hydrogen energy source, wind energy source, solar energy source, biomass energy source and hybrid energy source, regeneration drive system for motor and motor testing regenerative system.    ADVANTAGE - The method enables the inductor to operate according to selected characteristics in conjunction with high current and without excessive heating or to operate within safety compliance temperature requirements, thus increasing robustness of a filter with fewer moving parts and minimizing cost and packaging size.    DETAILED DESCRIPTION - The potting material is selected from a group consisting of urethane, multi-part urethane, polyurethane, multi-component polyurethane, polyurethane resin, resin, polyepoxide, epoxy, varnish, epoxy varnish, copolymer, thermosetting polymer, thermoplastic and silicone based material. The additive is selected from a group consisting of sand, oxide of silicon, silica sand, amphoteric oxide, aluminum oxide and glass. An INDEPENDENT CLAIM is also included for an electrical apparatus comprising an inductor core.
