ABSTRACT

To develop a piezoelectric linear motor with high precision, large stroke and strong thrust, a non-resonant piezoelectric linear motor with alternating normal contact force is developed. The motor adopts four piezoelectric stacks to excite the non-resonant state vibration of two driving feet, which alternately push the mover to generate unidirectional motion. On the basis of working principle analysis, the structure of the motor is designed and manufactured. The testing results show the feasibility of the motor. The operating results also shows that the flatness of the contact surface greatly affect the performance of the motor. The design criteria of the motor are proposed, which provides a basis for optimization of the motor.

Keywords: Piezoelectric linear motor, Piezoelectric stacks, Alternating normal contact force, Non-resonant.
