Comparison study between three kind superconducting motors

Abstract

In this paper, a comparison is made between three superconducting motors. The first one is based on the magnetic flux concentration principle. The second and the third motors have a conventional topology and contain a NbTi wire in the place of copper in the inductor. For the three motors we consider the same active length, the same armature and the same NbTi wire length. The comparison between the three motors is based on the created magnetic flux density in the air-gap. Calculations are carried out using the Monte Carlo Method for the first motor and FEM for the second and the third one.
