Conventional multi‐degree‐of‐freedom drive systems need many single‐degree‐of‐freedom actuators, but this makes the structure larger and heavier. The development of a spherical actuator should reduce the number of actuators, but the low torque and narrow rotation range are still problems. We developed a 2‐degree‐of‐freedom spherical actuator with an outer rotor that can produce a higher torque and wider rotation angle. In this paper, we propose a control method; we confirmed its usefulness by performing dynamic analysis using the three‐dimensional finite element method and by taking measurements with a prototype. 相似文献
