Although planetary gear sets are widely used in hybrid vehicles as a power distribution system and in electric vehicles as a high reduction system, its noise and vibration problem has emerged. There are many reports dealing with two-axis driving or displacement of planet gear under its condition, but we can see few reports dealing with three-axis driving. In the present report, three-axis driving is tested with three-axis rotation speed measuring and dynamic characteristic is investigated creating sun gear speed contour map. As a result, it's confirmed that rotation direction of the sun gear is changing under the three-axis transition. Accordingly, the input acceleration of the ring gear and carrier must be considered under three-axis driving to make the sun gear rotation direction invariable. Dynamic characteristic on a stationary rotation is affected by displacement length and speed of instantaneous center on the three-axis transition.
