This article deals with the analytical modelling of piezoelectric cylindrical micromotors [Morita etal., Jpn J. Appl. Phys. 35, 3251 (1996) and IEEE Trans. Ultrason. Ferroelectr. and Frequency Control 45, 1178 (1998)] and supplements the kinematics analysis of Pin Lu etal. [Sens. and Actuators A 87, 194 (2001)]. The modelling, based on an equivalent electric circuit, is established using geometrical and electromechanical parameters for the different parts of the motor. It gives electromechanical characteristics and other useful values for motor design.
