PURPOSE:To delete the quantity of high frequency cables and to reduce electric facility components by integrally associating a power source for supplying power to a high speed rotor drive motor in the lower portion of a casing of a high speed rotary machine. CONSTITUTION:In a high speed rotary machine in which a high speed rotor 1, a bearing 2 and a high speed rotor drive motor 3 are contained in a casing 4, a power source for supplying power to the motor 3 is integrally associated in the lower portion of the casing 4. Thus, since a high frequency cable for connecting the power source with the machine can be eliminated, the voltage drop of a reactance, proximity effect and skin effect are not necessarily considered. |
