<p>A magnetic spring arrangement for a resonant motor comprises a housing, a center element (66) mounted for rotation about a central axis, the center element (66) having magnets (68, 70) positioned on opposing portions thereof with opposing polarities facing outwardly therefrom, wherein the center element (66) has a workpiece assembly extending therefrom for rotational action of the workpiece, fixed magnets (76-79) positioned adjacent an outer surface of the center element (66), and a drive assembly with an AC drive signal for driving the center element (66), wherein the polarities and the position of the fixed magnets (76-79) are such relative to the polarities of the magnets (68, 70) on the center element (66) that there is a magnetic interaction between the fixed magnets (76-79) and the mounted magnets (68, 70), resulting in an oscillation of the center element (66), the motor characterized by the absence of mechanical springs.</p> |
