Abstract
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.
