MAGNETIC SLOT WEDGE WITH LOW AVERAGE PERMEABILITY AND HIGHMECHANICAL STRENGTH

摘要

MAGNETIC SLOT WEDGE WITH LOW AVERAGE PERMEABILITY AND HIGH MECHANICAL STRENGTH A magnetic wedge fox use in toothed stators holds the stator windings in the slots formed between the teeth of the stator. The magnetic slot wedge comprises a nonmagnetic body, with a width corresponding to the width of the slots. The nonmagnetic body has parallel laminations of magnetic material extending part way through the width of the magnetic body form both sides of the magnetic body and perpendicular to the top surface. A central nonmagnetic region is thereby created with a region on either side of the central portion having an average permeability, along its length, substantially in the range of about 5-10.
