Abstract

A novel type of single-phase tubular linear induction actuator is introduced. Its design and prediction of steady-state performance aided by nonlinear, time-harmonic, axisymmetric, finite-element theory are described. For prediction of transient performance, an axisymmetric, time-stepping, finite-element model that includes a velocity term in the field equations is presented. Movement is allowed for by a combination of mesh distortion and remeshing. This model couples the internal electromagnetic field to the external electrical circuit powered by a voltage source with arbitrary time variation
