In this study, we evaluate the performance of permanent magnets (PMs). The efficiency of attraction in the
high speed region was studied using the Variable Flux Memory Motor (VFMM). It is presented in order to
analyze the magnetic characteristics of PMs, using the second quadrant plan data with re- and demagnetization. In addition, this study focuses on the evaluation of operational characteristics relative to the magnetizing directions according to the d-axis currents, by using one of the finite element solutions. The feasibility of application for the VFMM has been experimentally demonstrated.
