I am using IPM machine with D shaped magnets. While adopting random winding with 16 number of turns I have back emf value as 70V. However, Keeping the same number of turns in hairpin (8 layer,4 parallel path) I observe 4% deviation in back emf keeping same magnet temperature, geometry and materials.
