ABSTRACT:
Armatures for dynamo-electric machines are balanced during manufacture by measuring the unbalance of the armature assembly prior to winding the coils on the armature. The numbers of turns of wire in at least some of the coils subsequently wound on the armature are then adjusted so that the unbalance of the resulting coils compensates for the unbalance of the armature prior to coil winding. In addition, masses may be added to the armature to ensure that it is balanced dynamically as well as statically.
