ABSTRACT:
The balance of rotors for dynamo-electric machines (e.g., electric motor armatures), which are wound with two diametrically opposite, simultaneously applied coils of wire, is improved by ensuring that wire is fed to both coils in substantially similar quantities. This can be accomplished by monitoring the consumption of each wire as it is fed to its respective coil, and adjusting the tension with which at least one wire is fed to its coil to substantially equalize the wire consumptions. Alternatively, the tension at which both wires are fed to the coils is monitored, and the tension of at least one wire is adjusted to equalize the tension of the two wires.
