Abstract

Recently, industrial machines and electrical equipment with multi-degree-of-freedom (multi-DOF) mechanisms have become complicated because many single-degree-of-freedom motors are used. A multi-DOF actuator is expected to solve this problem. We have proposed various multi-DOF actuators. However, they have some problems such as low torque and narrow rotation angle. This paper describes a new 2-DOF actuator with an outer rotor, which rotates widely. The operating principle is described, and the torque characteristics are clarified through the 3-D finite element analysis.
