Abstract

In an electric motor, each pole piece has an opening, preferably of a diamond shape, filled with a slug 63 of aluminum. Said opening and said slug align the magnetic flux lines in the pole pieces under motor load (Fig. 6, not shown) and serve for the extraction of heat. Contraction on cooling of molten Al, or other non- magnetic or low magnetic permeability material poured into the opening, ensures protuberances urge together the laminations (Fig. 3, not shown). <IMAGE>
