Ultrasonic 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.
