Abstract

The focus of this paper is to design a small incremental linear motor that could have the potential performance for light load applications. Due to its superior piezoelectric coefficients, PZN-PT (Pb(Zn_1/3Nb_2/3)O₃-PbTiO) is considered as a fungible material to conventional PZT. For the design of a lightweight linear motor, PZN-PT piezoelectric actuator was utilized to drive the motor due to its fast resopnse time and high piezoelectric coefficient. Furthermore, this paper presents the design and expected performances of a PZN-PT inchworm linear motor. We propose a new method of inchworm motion based on a novel electrode design using a single rectangular rod of PZN-PT single crystal piezoelectric material. The size of the monolithic PZN-PT linear motor can be very small (a length less than 5mm). The motor has a high-resolution positioning capability.
