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

摘要

In the linear induction motor, the original equations of the secondary equivalent circuit quantities derived from the two-dimensional electromagnetic analysis were ex- pressed 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.
