Analysing the characteristics of specific torque in HTS quasi-diamagnetic motor by variation of rotor blade geometry

We presented a new concept for a superconducting electrical rotating machine in 2013 in which we have utilized the quasi-diamagnetic behavior of Type II high-temperature superconducting (HTS) materials in order to create repulsion force between the excited stator pole(s) and HTS rotor blade(s). We have investigated a new arrangement of this improved quasi-diamagnetic machine (QDM) with different rotor blade geometries by means of finite-element method simulations and analytical calculations. In this paper, we present the results of this investigation and identify the leading parameters to get the maximum torque.
