Torque-Slip Characteristic of Squirrel Cage Induction Motor by New FEA Technique

摘要

The present paper deals with a new technique of finite elements analysis (FEA) of the rotor cage induction motor which enables its application to the study of other electrical devices. This technique has the great advantage of enabling the determination of the torque-slip characteristic, of the currents and of other parameters, given that the motor is supplied by a nominal voltage, without requiring however a numerical analysis with motion (of the rotor). There are only harmonic analyses in the frequencies domain that are performed, that are determined by the corresponding slips and therefore the necessary time and hardware/software resources are much more reduced. The results obtained by this method are compared to those given by measurements and thus the accuracy of the method can be confirmed.
