There are certain repair processes that can impact the efficiency and reliability of electric motors. Prudent repair practices must not increase overall losses, and preferably should maintain or reduce them. In some cases, repairers can also employ the principles applied by the motor designers and further reduce losses and enhance efficiency. Most of the following material is taken from, or based on, the "The Effect of Repair/Rewinding on Motor Efficiency; EASA/AEMT Rewind Study And Good Practice Guide to Maintain Motor Efficiency." Stator Core Processing And Repair Concerns about the possibility of core degradation during the rewind process have been expressed since at least the early 1990s. Higher temperature rated core plate insulation material greatly reduces the possibility of core degradation during the burnout process. However, a best practice approach is to avoid the possibility of core damage no matter what type of core plate is used.
