A three-degree-of-freedom linear oscillatory actuator (3DOF-LOA) is expected to reduce the size and weight of haptic devices. However, it is difficult to simplify magnetic circuits and structures because of the need to generate forces in various directions in three dimensions. To solve this problem, we have proposed a novel 3DOF-LOA consisting of two permanent magnets and three coils wound in layer. This paper describes verification experiments of the proposed actuator. The detent force and the thrust force characteristics are measured and compare with the analytical results. Then, the dynamic behavior is investigated when a sinusoidal current is applied. As a result, it was revealed that the actuator is driven as the proposed operating principle.
