Impact Force Analysis in Inertia-Type Piezoelectric Motors

In an inertia-type motor, a piezoelectric multilayer actuator is espoused to transient vibration velocity as high 1.0 m/s during slip time. This makes the motors dynamic but not quasi-static. We propose kinetic model describe condition under which slippage can occur between slider and stator. The current absorbed by actuators in stator time defines behavior of slider. A new thickness-mode force factor expression (A33), relation velocity, described electrical domain. Impact acting on friction coupler produced proportional rate change sliding Additionally, we present structure characteristics two-phase inertia-drive-type proposed was evaluated. Driving with truncated mirrored sawtooth signals enhances system dynamics. As one expands other shrinks, their respective hysteretic nonlinearities are canceled. motor operating frequency be great 30 kHz typically load unloaded greater than 16.0 mm/s generated higher 3.0 N.
