Title:
磁気流体力学(MHD)アクチュエータ/センサ
Document Type and Number:
Japanese Patent JP5204391
Kind Code:
B2
Abstract:
An MHD sensor/actuator is provided for generating torque as well as sensing angular displacements around a sense/torque axis. A column of conductive liquid which rotates within a circumferential channel having an inner circumferential surface and outer circumferential surface provides an inertial proof mass, the relative motion of which within the channel generates a torque or represents a sensed displacement about the common axis of the circumferential channel. According to certain embodiments, a cylindrical column of magnets are located coaxially with the circumferential channel to produce a radially oriented magnetic field which is perpendicular to the common axis. According to other embodiments, a magnetic ring is provided coaxially with the circumferential channel to produce a magnetic field in the direction of the common axis.
