Abstract
Official abstract text for this publication.
A rotation driving system and a method to determine the presence of a rotator on a turntable are provided. The rotation driving system includes an encoder to detect rotation information of a motor, and a controller to determine whether or not a rotator is present on a turntable and also, to adjust a gain of the motor according to moment of inertia of the rotator.
First claim
Opening claim text (preview).
What is claimed is: 1. A rotation driving system comprising: a turntable configured to allow a rotator to be loaded thereon, the rotator having a shape of a disc and comprising at least one of an information-recording medium and a testing apparatus; a motor configured to rotate the turntable; an encoder configured to generate pulse signals according to rotation of the motor, and detect rotation displacement of the motor based on the pulse signals; and a controller configured…
