A 72-slot stator has a 4-pole, three-phase winding. Determine its coil pitch and the pitch factor. How many coils are in each phase group? Calculate the pitch factors for the following three-phase windings: (a) 36- slot, 4-pole, (b) 36-slot, 6-pole, and (c) 72-slot, 6-pole. Illustrate the place- ment of coils by sketches. COIL PITCH IN AN AC ARMATURE WINDING FULL PITCH WINDING COIL PITCH IN AN AC ARMATURE WINDING CALCULATING PITCH FACTOR TERMS 1. Coil Throw: The location in an armature core of the sides of a coil starting in slot number one (1). Example: the throw could be ... slots per pole would be 48 ÷ 4, or 12 slots per pole. ... MCQs on Armature winding - Unacademy MCQs on Armature winding are discussed, important Gate and other PSU questions asked in this chapter are discussed with neat diagrams

If the number of slots/pole/phase is fractional and superior to 1, the winding is called fractional-slot winding. If the number of slots/pole/phase is fractional and inferior to 1, the winding is called concentrated winding. Windings with the same number of slots/pole/phase q [math]q[/math] have the same winding factor. Step-by-step instructions for armature rewinding - General ... Page 1 of 2 - Step-by-step instructions for armature rewinding - posted in General Technical Info & Advice: Hi all, These are some scans of an old pamphlet from Simco Products, Inc. from 1966. Will a 3 phase, 3600 rpm induction motor only have 3 poles ... You could have a 36 slot stator for a 2 pole motor. You could have a 48 slot stator. You could allow multiple coils to be in a single slot. There are lots of ways to do it. Also, in a 3 phase motor, the phases will be 120 degrees apart. In a 2 pole motor the poles will be 180 degrees apart. In a 4 pole motor the poles will be 90 degrees apart.
