Abstract :
Recently, three-phase squirrel-cage induction motor (IM) has been frequently used as variable-speed motor driven by an inverter system. Generally, its losses increase and efficiency decrease when it is operated at high speed. Therefore, in this paper, we discuss the characteristics of eight motors with different gap lengths in relation to the experimental results.
