Performance analysis of induction machine with different types of magnetic material

Estimation of magnetizing reactance of Induction machines are very much essential for accurate computation of their performance and for calculation of their efficiency. The reactance of the magnetizing circuit is very much nonlinear in nature. It changes on the variation of load or type of operation like motoring operation or generating operation. This paper presents the iterative method to calculate the reactance of magnetization curve and then comparison is made for the performance of machines with three different magnetic materials for the magnetic circuit. MATLAB coding is used to compare the performance as Generator as well as Motor separately.
