Investigation of Equations for Calculation of Secondary Resistance and Secondary Leakage Reactance of Single-sided Linear Induction Motors

Abstract

In the linear induction motor, the original equations of the secondary equivalent circuit quantities derived from the two-dimensional electromagnetic analysis was expressed in combination with hyperbolic function and trigonometric function of complex number.
In this paper, it has been successfully investigated to deduce the equations for calculation of the secondary resistance and the secondary leakage reactance referred to the primary.
These equations are approximated by the Maclaurin's 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 various thickness of the secondary conducting plates.
