Parameters calculation of single- and double-cage models for induction motors from manufacturer data

This paper uses an easy technique to calculate directly the parameters for induction motors, using single- and double-cage models. This technique has been applied in a wide sample of 2167 induction motors, where the parameters have been calculated from manufacturer data. The results show that this technique provides large errors in the start and maximum torque points, but on the other hand, it provides small error in the full-load point, for both single- and double-cage models. For this reason, when the induction motor works near the full-load point, for example when there are some disturbances in the electric supply, this technique could be applied with good results.
