Where a normal concentric four-pole winding will have twelve groups of coils (four poles x three phases), a consequent pole winding will only have six groups. While the turns per slot will remain the same, it requires less time at the winding machine grouping coils. In a concentric wound motor, the coils are connected in a manner that will ...
