One of the main objectives in rewinding is to maintain the original performance characteristics of the machine. Our focus with this article will be on three-phase motor stator windings. If it is known that the winding in the motor was original and there is certainty that the as-found data is correct, the original winding can be duplicated with confidence by using the as-found data. However, in some cases there is uncertainty that the as-found winding had original factory data. In those cases, extra steps need to be taken as described here.
