Abstract : In accordance wtih this invention, a gyro is provided which has a bearing means between the rotor and stator provided by magnetic fluid and a caging means which also includes a magnetic fluid provided between the rotor and caging plate. The gyro of this invention includes a stator with motor windings mounted therein and presenting a concave type spherical surface and a spherical rotor is mounted inside the stator with permanent magnets embedded and mounted about the circumference of the rotor with magnetic fluid between the rotor and stator spherical surfaces and being held by the permanent magnets to provide a good fluid bearing between these spherical surfaces. Also, a flat caging plate has permanent magnets imbedded therein and mounted at one end of the rotor with magnetic fluid being held by the permanent magnets to provide a caging mechanism that can be removed from the rotor to substantially and virtually eliminate uncaging kick as the caging plate is removed from the rotor.
