Recently, higher efficiency is strongly desired for the three-phase squirrel-cage induction motor (IM). Therefore, induction motors are required to have smaller losses, which include iron loss, copper loss, mechanical loss and stray load loss (SLL). In this paper, the losses for eight 2.2kW IMs, which are driven by either a sinusoidal wave source or PWM inverter, are measured by a method based on the segregated-loss method defined by the Standard of the Japanese Electrotechnical Committee (JEC), and calculated using the type-T equivalent circuit direct method and the quasi-sinusoidal wave method. As a result, the higher efficiency techniques of IM in four manufactures are clarified. Moreover, it is cleary shown that the SLL is much larger than the SLL of JEC, and the type-T equivalent circuit direct method and the quasi-sinusoidal wave method are simple and accurate methods for the characteristic calculation.
