In this paper, in order to reduce the radial force and stabilize the torque, the design of a reluctance switch motor with a discrete rotor structure is simulated using Magnet software. For this purpose, first by examining the radial force acting on the rotor in different currents and situations from the area unaligned to aligned, a function called radial force function is introduced. Then, using the introduced function and the torque-current relationship, the phase reference torque is introduced so that the sum of the torque moments is equal to the reference torque of the motor. For experimental purposes, using Matlab software, the motor circuit and its drive are simulated, and by applying the torque function introduced as the reference torque, the results are compared with the results of the linear torque common function. And the simultaneous representation of the figure of the two radial forces obtained shows that the motor torque ripple is reduced and is almost the same as the torque in the linear common state. This is in a situation where the radial force decreases relative to the radial force of the linear joint torque. Manuscript profile
