Abstract

This paper presents the method of determining and characterizing of a piezoelectric stator profile that applying in an ultrasonic motor with the consideration of heat that was generated. The ultrasonic motor is driven by the vibration of the piezoelectric element in order to ignite a motion. The harmonic and transient analysis methods are used to predict the optimized operation frequency of the ultrasonic motor travelling wave. Then, the thermal analysis was conducted in order to analyse the heat distribution on the stator. The ultrasonic motor showed a different longitudinal defl ection with the increment of the temperature. Verification experiment is conducted through torque performance measurement. Travelling wave optimization was found to be strongly dependent on the heat that generated by piezoceramic material.
