を特徴とするスピンテスタの振動防止装置。 A drive shaft whose lower end is inserted into the vacuum chamber is connected to the spindle at the center of the axis of the specimen placed in the vacuum chamber, and a drive device outside the vacuum chamber vacuums the specimen through the drive shaft. In a spin tester that is rotated at high speed in a tank to examine the rotational strength of the specimen, a journal part is provided at the lower end of the drive shaft or the spindle of the specimen, and a magnetic field is arranged to surround the journal part. A bearing is installed in the vacuum chamber, and further includes a control device that controls electromagnetic force applied to the magnetic bearing based on signals detected from shaft vibration of the drive shaft and displacement of the specimen. Anti-vibration device for spin tester.
