This paper presents a symmetric hybrid transducer ultrasonic motor designed to produce large longitudinal vibration stress in the rotor/stator contact interface for high-torque operation. The nodal plane of the longitudinal vibration mode was adjusted to match the rotor/stator contact interface, and the piezoelectric ceramic disks for the longitudinal vibration were installed at the nodal plane of the longitudinal vibration mode for effective excitation. An experimental motor, 20 mm in diameter, using the first torsional vibration mode and the second longitudinal vibration mode was manufactured. A maximum torque of 0.8 N.m was achieved in the prototype, an improvement over previous versions.
本文介绍了一种对称混合换能器超声波电机，其设计目的是在转子/定子接触界面产生较大的纵向振动应力，以实现高扭矩运行。纵向振动模式的节面被调整为与转子/定子接触界面匹配，用于纵向振动的压电陶瓷盘安装在纵向振动模式的节面上，以实现有效激励。制造了一台直径为20毫米的实验电机，其使用了第一扭转振动模式和第二纵向振动模式。该原型实现了0.8 N.m的最大扭矩，相比之前的版本有所改进。
