Achieving Resonance with Piezoelectric Transducers on 2–4 Phase Resonant Electrostatic Induction Motors

This paper presents a study on the use of piezoelectric transducers as inductive elements for a 2–4 phase resonant electrostatic induction motor. A model for transducer impedance is presented and coupled to known motor characteristics to determine how to combine a given motor to a given transducer. This is substantiated with experimental measurements. Experimental verification of motor resonance was also performed, with successful results, despite some error and observation of non linear behavior. Motor thrust force was also measured, with the motor having producing around 300 mN, very close to the expected force output.
