摘      要：A novel double-foot piezoelectric linear motor is *** kinematic model of the motor under stepping motion is *** motor mainly consists of a stator with four piezoelectric stacks,a mover,a holding mechanism,and a preloading mechanism to achieve large stroke with high *** element simulations are carried out to analyze the motion characteristics of the motor.A prototype is fabricated and a serial experiments are conducted to validate the feasibility of the motor *** results indicate that the motor can move at a speed of 670.22μm/s with a driving frequency of 120 Hz and a voltage of 120 *** resolution of the proposed motor is 3.6μm while the resolution of the single-step motion is 0.1μm.
