Sometimes when redesigning a motor, the desired speed requires more poles than are possible for the number of stator slots. Or, a motor arrives in the service center with a nameplate speed that does not seem to be compatible with the number of stator slots (e.g.,18 poles with 36 slots). In both cases, the answer may be a part-salient, part-consequent winding.
