Abstract

In this paper the effect of various rotor core material for high speed Solid Rotor Induction Motor (SRIM) have been analyzed. A comparative study, regarding the performance of high speed SRIM on variation of various material properties has been made. It has been observed that a material with good electrical conductivity gives efficient operation. The effect of end ring length of SRIM has also been analyzed. A considerable variation in torque has been observed on variation in end ring length for 180 kW, 10200 rpm high speed SRIM. It was seen that the rotor with smaller end ring provided better torque but with lower power factor. The efficiency was also increased with smaller end rings.
