A lightweight inductor for the motor controller of an aircraft starter includes a toroidal inductor core divided into multiple sections that are separated by a thermally conductive, but electrically insulating, material. The inductor core is wound with wire and positioned inside of an electrically and thermally conductive container, which acts as a heat sink and EMI shield, while also reducing eddy currents within the inductor core.

Light-weight, conduction-cooled inductor

An electrical inductor assembly comprises an inductor core having a circular shape, a wire guide that surrounds the inductor core and includes a plurality of slots, at least one of the slots forming a path winding around the inductor core, and at least one wire placed in one of the plurality of slots to form a winding. A method of forming an electrical inductor assembly comprises forming an inductor core having a circular shape, surrounding the inductor core with a wire guide, winding at least one wire around the inductor core along a slot in the wire guide, and applying an insulating material to the slot containing the at least one wire to electrically insulate the at least one wire.

Electrical inductor assembly

A power inductor assembly includes and multiple coil sections disposed upon a mounting frame. Multiple winding sections each encircle one of the multiple core sections and a portion of the mounting frame. Air gap spacers separate adjacent core sections. The arrangement facilitates removal of thermal energy from the magnetic core. Lamination build direction normal to inductor mounting surface minimizes eddy current losses.
