Operation of a Quasi-Static Piezomotor in Transitory Frequency Range up to Resonance

Abstract:
Piezo motors are traditionally classified in two families: ultrasonic motors, operating at resonance, and quasistatic motors. However recent attempts have shown that some motor designs such as inertial motors could be used both in quasi-static and resonant mode.
In this paper, this approach is applied to a Piezo Actuator Drive (PAD). Experimental results demonstrate high torque in quasi-static mode and high rotation speed at resonance given the size of the motor. Furthermore, the motor can be operated over the whole frequency range, from 0Hz up to slightly above resonance without losing the position information. On the other hand, analysis shows that power requirements are high in the transition phase up to resonance and heat generation implies that only intermittent operation is recommended.
