Abstract
Abstract A stator winding includes three simultaneously wound winding patterns which are angularly spaced at 40*. Each winding pattern includes a series of 12 alternately oppositely wound coils in lapping relation to coils in the other two patterns, which coils all have a uniform span of 30*. Also disclosed herein is a method of producing the first mentioned stator winding.
