Abstract
A flux collector for an electrical machine includes a continuous strand of ferromagnetic material; and an electrical insulator covering the strand. The strand forms a tight cylindrical coil including a plurality of turns that are stacked axially. The insulator provides turn-to-turn insulation. The insulated wire is covered with a binder and cured. The strand can be a high permeability wire made of soft iron, silicon steel or cobalt steel. In the alternative, the strand can be a strip of METGLAS.RTM. amorphous alloy.
