18 May 2009Ultrasonic motor model and power analysis for industrial mobile applications
This article focuses on the power consumption characteristics of a linear piezoelectric ultrasonic motor in the
context of industrial mobile applications. Specifically, we analyze the power consumption of a commercially
available ultrasonic motor through the analysis of a phenomenological model that has been derived using only
the motor geometry and material data. The model is shown to provide rapid assessment of ultrasonic motors
in a variety of disparate industrial applications while exhibiting good fidelity when compared with measured
transient performance. Additionally, the model could be easily extended to other ultrasonic motor designs due
to the generic nature of the model structure.
