A lens-unit-swing system is composed of lens and an imaging device for image stabilizations. This system can correct an image from camera shakes over wide rotation ranges around three axes. On the other hand, this system has some problems such as an increase in size and power consumption. Therefore, three-degree-of-freedom actuators are expected to become a solution for these problems. However, it is difficult to incorporate these actuators in the system because the size is large and it has a complicated control system. In order to solve these problems, we propose a new three-degree-of-freedom electromagnetic actuator, which can be controlled by a simple control system. In this paper, the basic structure and operating principle of the actuator are described. Moreover, the modeling method of the actuator is described. In addition, the effectiveness of the actuator is verified through 3-D finite element analysis and numerical simulation.
