摘要：
As per IEC-60034-2-1, 2007, for a rotating electrical machine, the stray loss component increases with the decrease in the size of the machine. This causes a drastic reduction in the machine efficiency, especially in small a. c. motors. Using measures for reducing stray loss will greatly help in improving the efficiency of motors. This paper explores a novel method for reducing the stray loss in totally enclosed fan cooled (TEFC) induction motors. The concept of diamagnetic shielding has been used to reduce the stray loss occurring due to leakage of flux from stator's outer surface. Electromagnetic Analysis based on Finite Element Analysis (FEA) has been used extensively for this study. The effectiveness of the method has been highlighted by analyzing flux plots generated by electromagnetic software, Maxwell.
