Transient and Static Modeling of Tubular Linear Induction Motors

This paper is concerned with the transient modeling of tubular linear induction motors with blocked rotor in the assignable respective positions of rotor and stator. The motor is a traveling-wave generator- driven type. This work is based on calculation of self inductances of a link and a coil, mutual inductance and mutual inductance gradient of coaxial coils with current filament method, assumption of the rotor constituted of some rings, and current calculation of stator coils and rotor rings with respect to time. We have written some computer codes for calculating inductances and analyzing the performance. Finally the instantaneously force applied on rotor is calculated.
