Elliptical Motion

A new ring-type linear ultrasonic motor is proposed in this study. In this new design, bending vibration traveling wave is generated in a long ring by two groups of PZT ceramics bonded on the inner sides of the linear beams. Elliptical trajectory motions can be formed at particles on the teeth, which can realize the linear driving by frictional force. The working principle of the proposed design is introduced. Two bending vibration modes that have a phase difference of 90deg on space are analyzed. The elliptical motion trajectory of node on the tooth gained by the transient analysis verifies the excitation of bending traveling wave. A prototype motor is fabricated and measured, and a maximum speed of 15mm/s is reached.

This paper presents an optimal design for an in-plane traveling wave rotary ultrasonic motor with a composite transducer. The structure of the stator was improved to minimize negative influence on vibration modes from the supporter, and a new stator based on it was designed and fabricated. Two operating modal frequencies of new stator have been adjusted to equality by reducing one structural parameter according to sensitivity analysis. The performance experiments of the prototype motor shows that maximum no-load speed is 450rpm and maximum torque achieves 0.04Nm at an exciting voltage of 200Vrms.

To take advantage of merits of higher output-power and efficiency of bolt-clamped transducer, a ring type traveling wave ultrasonic motor using cantilever type composite transducer is proposed in this paper. In this new design, two cantilevers are set for the coupling between ring and transducer. Two standing bending waves (with phase difference of π/2 on time and space, respectively) are generated in the ring by the bending-longitudinal vibrations of transducer. Thus, a flexural traveling wave can be excited. The working principle of proposed motor is analyzed. The stator is designed and analyzed with FEM, and the motion trajectories of nodes on the teeth are analyzed. The results of transient analysis verify the theoretical feasibility of proposed design. The results of this paper could guide the development of this new type of motor.
