Introduction to Testing the new winding
Later than the connections and rewinding are completed; it is significant that both the winding and the connections are checked for shorts, grounds, open circuits and accuracy of connections. This has to be completed before varnishing the winding that is why any defect that is found may be corrected much more readily.
Baking and varnishing:
Later than the armature has been soldered, wound, banded and checked, the next operation is varnishing. This procedure makes it moisture-roof and also avoids vibration of the coils of wire in the slots. Vibration comprises a trend to impair the insulation on the wires and cause shorts. Moisture will also results the insulation on the wires to deteriorate. Earlier than the varnishing the armature, it have to be reheated to drive cut the moisture on it. Armatures might be varnished through either baking varnish or air-drying varnish. Air-drying is applied to the armature while baking is not desirable or inconvenient. Baking varnish is more efficient because the moisture can be eliminated fully only through baking.
Balancing the armature:
Armatures should be checked for mechanical balancing later than they are varnished. This is very significant; if not undue vibration and unusual noises may be generated because of the imbalance of the armature. Finally it might lead to repeated bearing problems, loosening of nuts etc. Therefore the armatures are balanced previous to the assembly. Balancing of armature is essentially done, by using dynamic balancing machines. Anyway for small armatures static balancing can be done, while dynamic balancing machines are not presented.
Static balancing:
A balancer, identical to the balancing grinding wheel in machine shops, might be employed. These balancers are developed in several sizes. The technique of balancing an armature using this type is as follows:
Put the armature on the balancing ways, as displayed in the below diagram and roll the armature quietly. While the armature comes to a shop, the heavy portion of the armature will be at the bottom. Mark this point or portion with a piece of chalk. With such type of a successive rolling, if the armature stops at dissimilar positions, the armature is balanced, and if it stop in a specific position, it is essential to counterbalance it with weights diagonally opposite to the heavy portion.
This is accomplished through the lacing a lead or a small metal piece on the armature's banding. In small armatures, this weight might be laced in the lace of the wedge, within the banding. Experience will ascertain the amount of metal essential to balance the armature. This technique of balancing is termed as "static balancing'.
Dynamic balancing:
Dynamic balancing machines are presented to balance the armature / rotating the arts of electrical machines. The armatures are set on those machines and rotated at the rated seed. A pointer or an indicator depicts the location on the armature and the weight to be added. The balancing machines presented are either with the stroboscopic balancing or mechanical balancing.
