The diagram below explains the complete main winding diagram for 3 phase 4 pole 24 slots double layer lap winding. Question: build up the layout of a lap winding for a 3 phase ac machine comprising 2 pole and 24 slots. There are 2 coil sides per slot. Solution: Coil groups per phase = 3 x 2 = 6. Slots per pole per phase, m = 24/(3*2) = 4 What do you mean by number of poles per phase in a machine? 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. A New 4/6 Pole-Changing Double Layer Winding for Three Phase ... ΦΦΦΦAbstract-- The paper presents a new double layer three phase 4 to 6 pole-changing winding, with 48 slots and 6 terminals. In order to obtain a higher fundamental winding factor when ...

jimhendershot.com coil winding pitch. Figure I-D is a common brushless configuration for (3) phase motors with (4) poles, (12) slots and a (3) slot coil winding pitch. Figures I-E and I-F are brushless designs with (6) pole imbedded rotor magnets. Figure I-E represents a (4) phase motor with (12) slots and a (2) slot coil winding pitch. Figure I-E is a (3) phase ELECTRICAL MACHINES II - uotechnology.edu.iq b. Fractional-slot winding can be used c. Chorded-winding is possible d. Lower-leakage reactance and therefore , better performance of the machine e. Better emf waveform in case of generators. 6. Pole – pitch. A pole pitch is defined as the peripheral distance between identical points on two adjacent poles. Pole pitch is always equal to 180 o 7.
