Abstract
A stator formed of a dual-out stator lamination is disclosed. The stator comprises a generally annular core including a plurality of arcuately spaced apart teeth. Each of the teeth includes a generally radially extending leg and a head extending generally arcuately relative to the leg to present opposite head ends spaced from the leg. The head presents a tooth head height measured in at least a substantially radial direction. Each adjacent pair of said heads is spaced apart by a generally arcuate slot opening distance defined between the adjacent ends of the pair of heads. The ratio of each tooth head height to each adjacent slot opening distance is at least about twenty-eight hundredths (0.28).
