3-D dynamic simulation of an integrated levitation, guidance and propulsion system by a superconducting transverse flux linear motor

This paper presents a transverse flux linear motor (TFLM) with the superconductor-aluminum hybrid as the secondary and E-shaped ferromagnetic yokes wrapped the conductor windings as the primary to generate the transverse flux, the hybrid secondary is made of aluminum plate and close-ended coated superconductor coils, with the latter placed over the former to realize the stable levitation, guidance and self-propulsion. In this paper, a multi-degree of freedom 3-D finite-element dynamic model of such superconducting TFLM was established, in which the actual geometry of the motor and the nonlinear behavior of superconductor were represented. We investigated the transient characteristics and dynamic responses against disturbance and also studied the influence of aluminum plate on the overall performance. The obtained characteristics of the dynamic superconducting TFLM model may offer a reference for dynamic experiments and control strategy.
