Electric motor repair has the potential to impact future motor life, energy efficiency and the environmental impact of the machine (electric motor, to be used interchangeably in this paper) even when meeting modern motor repair standards. In this paper we shall outline the impact of repair following repair standards versus traditional repair and relate both scenarios to Precision Motor Repair (PMR), or Reliability-Centered Motor Repair Practices (RCMRP). The outline of impacts will be based upon the allowable limits by standards, observations following traditional practices, the impacts measured through PMR, based upon three similar machines in which an IEEE 112 Method B (segregated loss) was performed. These evaluations will be based upon expectations of impact to new core steels in premium and energy efficient machines.
