The structure and working principle of a new generation of variable speed governor R801 was briefly introduced. The flyweight's parameters such as volume and moment of inertia etc, which have most effect on governing characteristic were accurately calculated by three dimension solid modeling, and on the basis of this, the mathematical models for the lift of flyweight and the movement of governor were built in a meticulous way. Instead of using traditional method that depends on experiment wholly to get the governing characteristic, the operating characteristic of R801 governor was simulated by mathematical models, and the effects of different profiles of limit cam on the governor's operating characteristic were discussed also. The experimental verification shows that the model can predict the governing characteristic of R801 governor closely, and it can instruct how to match limit cam with governor, furthermore, the method of this paper can be used for reference to other governors.
