1. CHAIN WINDING In all aspects, this winding is similar to that of mush winding except that both coil sides of a coil have equal length and diamond shape.

2. Diamond shape

3. Example#2: on Chain winding Given data S=12; p=2;m=3; a=1; type=Chain Solution a)The number of coil groups, K b)The number of slots per pole per phase, q c)Coil pitch This is an even number and hence winding is not possible with an even coil span. There fore, it is shortened by one slot and a coil span of 5 slots is used. d)The electrical angle,  e)The angle between adjacent slots,  f)The distance between the beginning of each phase, g)If the beginning of Phase A is slot 1, then the beginning of phase B is slot 1+ =5 and the beginning of phase C is slot 1+2 =1+8=9 Full-Pitch i.e. there are two coils in a group i.e. there is one coil group per phase
