<P>PROBLEM TO BE SOLVED: To prevent deterioration of fluid performance during a rated load operation of a turbomachine and to reduce vibration stress to moving blades caused by slip stream of stator blades during partial rotation speed operation. Ž<P>SOLUTION: The turbomachine is equipped with a rotor having a plurality of moving blades extended in the radial direction on its outer periphery, a casing rotatably holding the rotor thereinside and forming a flow passage for leading a fluid to the moving blades to the rotor, and a plurality of variable stator blades distributed in the circumferential direction in the flow passage formed in the casing and in which mounting angles can be changed during the partial rotation speed operation. The variable stator blades are uniformly distributed in the circumferential direction of the casing and the change amount of mounting angles during the partial rotation speed operation are non-uniform.
