FIG. 1.

The (a) oblique view of a finite element mesh used to model the stator for the motor alongside (b) a completed prototype stator. Notice the slider sits atop the pair of fins; the fins are a pair of cantilever beams mounted at an angle with asymmetry and have different fundamental flexural resonances if (c) the end masses are different. Depending on the relative size of the tip masses to the beams’ length, they either (d) reduce the resonance frequency (mass effect) or increase it (stiffness effect).
