Title:
INERTIA WHEEL
Document Type and Number:
Japanese Patent JPS53114200
Kind Code:
A
Abstract:
An inertia wheel more particularly adapted to space applications. It includes the combination of a peripherical type of motor with permanent magnet on the rotor and ironless winding on the stator. The current of said winding is switched electronically by an amplitude modulation system, associated to a reactance coefficient varying circuit, and reversal of the direction of rotation of which is achieved by permutation of the control circuits. There are also provided bearings formed by a passive radial magnetic centering device and a redundant active axial magnetic centering device slaved to an axial rate detector.
