振荡执行器 (OA) 用于工业设备和家用电器等各个领域。例如，它们应用于主动隔振台、振动测试设备和触觉界面。它们具有短行程的多自由度 (DOF) 机构。这种传统机构由一些致动器和连杆组成，因此，振动中心发生偏移，并且尺寸和重量增加。为了解决这些问题，人们开发了各种类型的多自由度OA。然而，五自由度 OA 尚未提出。为了通过增加自由度进一步实现该功能，我们提出了五自由度 OA。阐述了其基本结构和工作原理。使用三维有限元法通过磁场分析来研究推力和扭矩特性。分析结果表明，所提出的执行器可以驱动五个自由度，而其他轴之间不会发生干扰。
Oscillatory actuators (OAs) are used in various fields, such as industrial equipment and home appliances. For example, they are applied in active vibration isolation tables, vibration test devices, and haptic interfaces. They have a multiple-degree-of-freedom (DOF) mechanism with short-stroke. Such conventional mechanisms consist of some actuators and links, therefore, the vibration center is shifted and the size and weight increase. To solve these prob-lems, various types of multiple-DOF OAs have been developed. However, a five-DOF OA has been not proposed. To further realize the functionality by increasing the DOF, we propose a five-DOF OA. Its basic structure and operating principle are described. The thrust and torque characteristics are investigated by a magnetic field analysis using a three-dimensional finite element method. The analysis results indicate that the proposed actuator can drive five-DOF without interference between other axes.
