Title:
【発明の名称】回転体に対する電磁的回転加振装置及びそれを用いた回転体の制振装置
Document Type and Number:
Japanese Patent JP2997632
Kind Code:
B2
Abstract:
An apparatus for electromagnetically and rotationally vibrating a rotary body supported by bearings. The apparatus comprises a ring-shaped magnet bipolarly magnetized and mounted on a shaft of the rotary body coaxially, a ring-shaped stator having a coil and adapted to generate a rotating magnetic field by controlling an electric current supplied to the coil, and a frequency-variable vibration power source adapted to supply alternating electric power to the coil in the stator. The magnet and the stator have different magnetic radii and are disposed so as to be opposed to each other in a direction identical with the magnetization direction of the magnet. Thus the rotational exciting force is applied to the rotary body by an interaction of the rotating magnet field generated by the stator with the magnet. This electro-magnetic rotary vibrator can be applied to a damper for offsetting the unbalanced vibration of a rotary body.
