This paper presents a simplified theoretical model for piezoelectric motor based on synchronized switching control. The influence from driving voltage, duty cycle and load to the stepping motion and velocity of the motor was analyzed in this study. It proved that the step size is a function of the driving voltage and the velocity of the motor decreases with an increased load and reduced duty cycle on macro point of view.

Helical Parameters

The bacterial cell is propelled through the liquid environment by means of one or more rotating flagella. The bacterial flagellum is composed of a basal body (rotary motor), hook (universal coupler), and filament (propellor). The filament is a rigid helical assembly of only one protein species — flagellin. The filament can adopt different morphologies and change, reversibly, its helical parameters (pitch and hand) as a function of mechanical stress and chemical changes (pH, ionic strength) in the environment.
