There are two special cases in the motor rotation, that is, no-load and stalled. The data used to support the findings of this study are available from the corresponding author upon request. The investigations showed that the proposed linear motor can produce a six times higher power density than that of a previously reported square plate motor. Due to the asymmetry of the stator, inevitable manufacturing errors, or imbalance of the excitation voltages, the amplitudes of the two-phase standing waves cannot be exactly the same, resulting in unstable operating of USM.
