     · Therefore, an air gap between 0.5 and 1 mm is a reasonable value, considering both magnetic flux density and feasibility of fabrication. It is selected to be 0.5 mm in this study. The thicknesses of the steel plates and the permanent magnets are selected to make sure that the magnetic flux densities inside them are not saturated.
