Wireless trams with independently rotating wheelsets require fast and precise torque control performance. In order to achieve this, torque control using flux-based 2D-LUT is most suitable. This makes it possible to easily convert the torque command into a current vector, and it is possible to perform stable torque control even if the battery voltage fluctuates greatly, such as in a wireless tram. In this paper, flux-based 2D-LUT generation method and torque control using FEA are studied. The validity of the proposed method is verified through simulation.
