This paper proposes a kind of 3 degree-of-freedom spatial parallel micromanipulator driven by linear ultrasonic motors, as well as the kinematic and dynamic analysis. The micromanipulator is a parallel mechanism jointed by flexible hinges. It has two fingers and the moving finger is driven by linear ultrasonic motors which possess plenty of advantages such(More)
This paper proposed structural design methods for the development of high-efficiency linear ultrasonic motors (LUMs) that can be applied in robotic fields. A continuous variable cross-section Langevin vibrator was adopted for higher vibration efficiency of the stator. To improve the structural stability of the motor, the clamping component of the stator and(More)
In this contribution, we propose a novel linear piezoelectric motor with a compact stator that is driven by a single mode. The linear piezoelectric motor can realize bidirectional motion by changing the vibration modes of the stator. Finite element analysis is performed to determine the required vibration mode of the stator and obtain the optimal stator(More)
