In this paper, wound rotor induction modeling has been presented by modified Magnetic-Equivalent-Circuit (MEC). Generally, there are two separate sets of equations which are differential equations (relative to electrical part) and nonlinear algebraic equations (relative to core’s magnetic parts) which were solved separately in previous works. This caused to ambiguous manner and some of dynamic behaviors may be loss. In this paper the differential equations are converted to algebraic equations by trapezoidal method and a set of nonlinear equation are solved by Newton-Raphson technique. This manner is introduced as the paper novelty. Proposed manner is capable to modeling of a wound rotor machine with given slot and poles number and also arbitrary magnetization curve. Moreover, another machine types could be modeled by proposed method. Finally, performed validation by Finite-Element-Method shows the effectiveness of proposed method.
