TASK 3: Perform winding of armature
1 Select the winding wire according to the original winding and mount the spool on a stand.
For sumeet mixer use winding wire of size 30SWG.
2 Insert a guide paper in the identified slots in which the coil is to be placed. (Fig 9)
For the sumeet mixer, taken as an example, we have
Total number of slots = 12
Segments = 24
Winding wire = 30 SWG
Number of coil sides in each slot = 4
(2 coil sides are looped together and the loops are connected to the segments)
Number of turns in each coil = 36 turns identified slot pitch 1-6.
3 Place a guide paper in slots 1 and 6. (Fig 9)
4 Hold the armature in hand. (Fig 10)
Large size armatures are to be supported by stands (horses during winding). (Fig 11)
5 Wind the armature by hand placing one end of the coil side in slot No.1 and the other in slot No.6
6 Count 36 tuns and then make a longer loop.
Do not make mistakes in counting. Wrong number of turns will result in unbalanced armature.
7 Make another 36 turns in the same solts (1 and 6) by holding the loop with your fingers of the hand.
