A novel 16/6 phase modulated winding

Many authors have presented various types of wide ratio pole changing windings. Some have done that using the principles of pole amplitude modulation (PAM) technique and others have resorted to the use of phase modulating (PM) technique. It has been reported that difficulties arise for wide ratio phase modulated windings when one of the pole numbers is triplen. This paper presents a novel wide ratio phase modulated winding which includes a triplen pole number.
