Abstract :
H. Oraee (ibid. vol. 7, pp. 790-796, 2000) presented a timely analysis. However, since I originated this research and guided the author in his initial approach, I feel that I must share some observations with readers who want to learn more about induction motor thermal aging caused by voltage distortion and imbalance. The following observations and comments are meant to help engineers interested in the continuation of this work.
