Induction machine stray loss from inter-bar currents

[摘要] (cont.) A number of different cast copper and aluminum five and ten horsepower test induction motors performed differently than originally predicted and variably between nominally identical machines. Inter-bar currents are part of the cause of both the variation and additional losses measured on these machines. The adjusted equivalent circuit equations improve estimations of motor performance and allow identification of means to increase machine efficiency by minimizing the stray load loss due to inter-bar currents.
