The development of a linear hybrid transducer type piezoelectric motor is shown. This design has the advantages of light weight, macro and micro positioning, and large force/velocity output. The motor consists of a longitudinal actuator that provides output displacement and force, and two alternating clamping actuators which provide the holding force. The advantages of this design over other types of piezoelectric motors are shown. Significant design considerations for the development of a piezoelectric motor (including material choices, shear loads on piezoelectric-materials and contact surface interaction) are discussed. A simulation, including a finite element analysis of the system, is used to predict the motor response to various input sets. A prototype motor is built and its characteristics are compared to theoretical predictions.
