In case of a 4-pole D.Sep 21, · The winding of a 4-pole alternator having 36 slots and a coil span of 1 to 8 is short-pitched by.. degrees. A B. 80 C. 20 D. 40 Explanatory answer: Pole pitch: Centre to centre distance between two adjacent poles Pole picth= deg electrical Pole pitch= slots/Pole= n Coil span: The distance between two coil sides of acoil. Nov 11, · * is not an integral factor of Unless a slot is partialy wound for each pole an eight pole motor would require a 24 or 48 slot stator. As stated above, 36=3*3*2*2. 48=3*2*2*2*2 I think that 36 slot stators could be used at least for 2,4 and 6 pole motors. I would expect that 48 Slots would make at least 2,4 and 8 pole motors. Jul 20, · have a polarity 60 degrees apart (which creates a 12 pole motor with 36 slots), the effective winding is reduced to 1/4 of the ideal. I have not done all of the calculations, but the 2 pole and 4 pole designs should be close to ideal, but the 6 pole is probably reduced to about 50%, and it drops to 25% for 12 pole.
