An ultrasonic motor as a kind of smart material drive actuator has potential in robots, aerocraft, medical operations, etc. The size of the ultrasonic motor and complex circuit limits the further application of ultrasonic motors. In this paper, a single-phase driven ultrasonic motor using Bending-Bending vibrations is proposed, which has advantages in structure miniaturization and circuit simplification. Hybrid bending vibration modes were used, which were excited by only single-phase voltage. The working principle based on an oblique line trajectory is illustrated. The working bending vibration modes and resonance frequencies of the bending vibration modes were calculated by the finite element method to verify the feasibility of the proposed ultrasonic motor. Additionally, the output performance was evaluated by experiment. This paper provides a single-phase driven ultrasonic motor using Bending-Bending vibrations, which has advantages in structure miniaturization and circuit simplification.

A prototype for multi-mode linear ultrasonic motor has been proposed and designed. It is designed using a combination of the first longitudinal and the first bending mode. The piezoelectric ceramics convert energy using the longitudinal d33 effect which allows an improved reliability, large vibration amplitudes and excellent piezoelectric coupling. The normal direction motion of the driving element is excited by the first longitudinal mode. The tangential direction motion of the driving element is excited by the first bending mode. The resulting displacement of the driving element is transmitted by the frictional force between the vibrator and the rail in a linear motion. The analysis on the modals of the composite vibrator by using the ANSYS finite element software has been presented in this paper. Finally, the vibrator structure of the motor and the motor's own structures are designed. The basic design is discussed and simulations are compared with the experimental results, the results show that the motor characteristics can be optimized for a particular task by choosing the appropriate operating parameters such as exciting voltage, exciting frequency and normal force.
