Abstract:A novel non-resonant piezoelectric linear motor with multiple working mode is proposed in the paper. Design and modeling of the stator is presented and the working mechanism of three working mode are introduced. The three working mode is continuous actuation mode, alternative step actuation mode and one-step actuation mode. With the help of finite element method (FEM) software, the arrangement of motor, clap mechanism and preload mechanism are designed and researched. The prototype is manufactured to validate the feasibility of motor under the three working mode. Experiment results show that, the velocity of motor is 446.4μm/s under sine signal with a voltage of 100 V and a frequency of 100 Hz in continuous actuation mode. In alternative step actuation mode, the velocity of motor is 6031μm/s with a voltage of 100 V and a frequency of 100Hz. In one-step actuation mode, the average step distance is 333.33 nm with a voltage of 30 V and a frequency of 1 Hz. The novel linear motor can meet different demands under multiple situation.
