ABSTRACT:
A lightweight electromotive device with a high power-to-weight ratio capable of operating as an efficient motor, alternator or generator includes an mangetic-flux producing assembly comprising spaced magnetic elements, and an armature assembly formed by winding conductive, non-magnetic wire, such as copper wire on flux carrying core or stator bar elements. The elements are shaped to form an eddy current shield for the windings and provide two heat radiating surfaces. This allows the device to operate with minimal eddy current losses and maximum radiation and convection cooling. The armature windings and flux carrying elements are dispersed as a further measure to avoid creating opposing induced currents.
