我们一直在开发能够三自由度旋转的电磁球面执行器。然而，这些执行器需要复杂的控制，因为围绕一个轴的旋转会干扰围绕另一个轴的旋转。在本文中，我们提出了一种新的三自由度执行器，其中三轴可以独立控制。介绍了该驱动器的基本结构和工作原理。然后用三维有限元方法计算了该驱动器的静、动态性能，验证了该驱动器的有效性。
We have been developing electromagnetic spherical actuators capable of three-degree-of-freedom rotation. However, these actuators require complex control because rotation around one axis interferes with rotation around another. In this paper we propose a new 3-DOF actuator where the 3-axes can be independently controlled. The basic structure and the operating principle of the actuator are described. Then the static and dynamic performances are computed employing 3D-FEM and the effectiveness of this actuator is clarified.
