  Wave Winding

Introduction to Wave winding

Build up the layout of a wave winding for a 3 phase comprising 4 pole ac machine and 24 slots. There are 2 coil sides per slot.

Solution: Coil groups per phase = 3 x 4 = 12. Pole pitch = s/p= 24/4= 6

Slots per pole per phase, m = 24/(3*4) = 2

Angle among the adjacent slots, â = 180/(24/4) = 300.

Here 3 phase groups per pole, each having of 2 slots. The distribution of slots, of phase sequence RYB or ABC, is displayed in the below table.

Back pitch, Yb = (2C/P) ± K = (2 x 24)/4 ± K= 12 ± K = 13

in terms of coil sides. The winding pitch employed for a 3 phase wave that connected ac machine, Y = 12m. Hence, Y = 12 x 2 = 24, the front pitch, Yf = 24 -13 = 11 in terms of coil sides. If the begin of R or A phase lies in slot number 1, the start of Y or B phase must be in slot number (1 + 120 /30 =) 5 and that of B or C phase in slot number (5 +120/30 =) 9.

This creates the phase sequence RYB. Half of the winding will be in clockwise and the remaining one will be in anticlockwise. Phase R begins with coil side 1 in slot number 1. The below table explains the winding table for R or A Phase.
