PURPOSE: A rotation apparatus for a turbine rotor is provided to stop a desired blade at an accurate position by controlling the operation of a motor based on a calculated rotation distance. CONSTITUTION: A rotation apparatus for a turbine rotor comprises a first supporter(21), a second supporter(22), a power transfer shaft, a speed reducer(60), a drive motor(70), an encoder, and a control device(100). A drive roller(31) and a driven roller are installed in the first supporter. Two driven rollers are installed in the second supporter. The power transfer shaft is coupled to the rotary shaft of the drive roller and rotates the drive roller. The speed reducer controls torque from the power transfer shaft. The drive motor rotates the drive roller through the speed reducer. Te encoder detects the rotation frequency of the power transfer hsaft. The conder device controls the drive motor depending on the detected rotation frequency information.
