The different thrust corresponds to the sine value of the phase difference of the permanent magnet flux linkage of the turn linkage of the stator permanent magnet and the permanent magnet attached to the surface of the bottom of the rotor in the rotor core. When the phase difference is 90 degrees, the mover receives the maximum external thrust. The magnitude of external thrust received by the rotor and the magnitude of torque acting on the rotor can be directly calculated by simply measuring the phase difference angle. Meanwhile, in the process that the external thrust is increased from 0N to the maximum, the closed magnetic circuit of the stator permanent magnet does not demagnetize the permanent magnet attached to the bottom surface of the rotor, and vice versa.
