Squirrel-cage induction motors play an important role in the world’s industry. Hence there is a strong demand on their reliable and safe operation. Their faults and failures can lead to excessive downtimes and generate enormous costs due to reduced output, emergency maintenance and lost revenues. In this paper a FEM model of a three phase squirrel-cage induction machine is presented. It is used...

A speed tracking control method for induction machine is shown in this paper. The consists of outer loop and inner current loop. Model predictive without the need calculation weighing factors utilized loop, which generates a continuous set voltage reference values that can be modulated applied by inverter to machine. Interesting parallels are drawn between developed state feedback principles he...

The detection of faults related to the optimal condition induction motors is an important task avoid malfunction or loss motor, thus avoiding high repair replacement costs and in efficiency process which they belong. These are not limited a single area; mechanical electrical problems can cause fault. Specifically, bearing motor subjected several effects that faults, significant breakdowns machi...

This paper presents performance evaluation of an asymmetrical parameter type two-phase induction machine drive using two-phase three-leg voltage source converter (VSC) operating in motoring and generating modes. A system is simulated using MATLAB/SIMULINK. The proposed converter system includes a machine side converter using a three-leg VSC and a front end converter using a single-phase full br...
