Abstract
An insulation insert (40) is provided for preventing electrical shorts and/or arcing between adjacent strands in a stator coil. The insulation insert includes a thin base (42) of substantially uniform cross section and a lead-in nose (43) formed in the thin base (42) for guiding the insulation insert (40) into a position between adjacent strands. The insulation insert (40) includes two substantially vertical cuts (45) in the thin base (42) above the lead-in nose (43), which delineate a center section (44) flanked by two ear portions (46). A head (54) and two wings (52) are formed in the insulation insert by folding the ear portions (46) along substantially horizontal creases (47).
Claims5
An insulation insert for preventing electrical contact or arcing between adjacent strands in a stator coil, comprising:
