| Abstract: | In the linear induction motor, the original equations of the secondary equivalent circuit quantities derived from the two-dimensional electromagnetic analysis were expressed in combination with hyperbolic functions and trigonometric functions of complex numbers. In this paper, we attempt to deduce the equations for calculation of the secondary resistance and the secondary leakage reactance referred to the primary. These equations are approximated by a Maclaurin expansion and are expressed by polynomial approximation. This paper also shows the variation of those equivalent circuit parameters with slip and the change of the operating characteristics with the thickness of the secondary conducting plates. © 1998 Scripta Technica.
