In order to facilitate the widespread application of ultrasonic motors, it is essential to conduct a quantitative study aimed at enhancing their performance. The present paper provides a comprehensive theoretical analysis of an ultrasonic motor equipped with dual vibrators, enabling operation in both the single-driven and dual-driven modes, thereby enhancing versatility in terms of performance adjustment. This study provides a detailed examination of the motor's unique performance characteristics and its varying output responses to different driving signals. Experimental investigations are conducted in both the single-driven and dual-driven modes to validate theoretical predictions. The results demonstrate that the motor exhibits a maximum speed, torque, and power that are 1.59, 1.28, and 1.62 times higher than those of the single-driven stator, respectively. A conclusion can be drawn that the motor will attain the desired performance when operated in the appropriate driven mode.
为了促进超声波电机的广泛应用，开展旨在提高其性能的定量研究至关重要。本文对配备双振动器的超声波电机进行了全面的理论分析，使其能够在单驱动和双驱动模式下运行，从而在性能调节方面增强了通用性。本研究详细考察了电机独特的性能特性及其对不同驱动信号的不同输出响应。在单驱动和双驱动模式下均进行了实验研究，以验证理论预测。结果表明，该电机的最大速度、扭矩和功率分别比单驱动定子高出1.59倍、1.28倍和1.62倍。可以得出结论，该电机在适当的驱动模式下运行时将达到预期性能。
