Display rotating apparatus preventing slip by rotary inertia |
摘要 |
A display rotating apparatus capable of preventing a slip phenomenon which occurs by rotary inertia. The display rotating apparatus comprises: a motor providing a driving force for rotating a display; and a motor driving device driving to rotate and stop gradually by increasing a rising time and a falling time of a rotation command signal. the display rotating apparatus can remove the slip phenomenon generated mechanically by increasing or decreasing slowly an applying voltage and/or current applied to the motor and reduce the sway by vibration at the time of stopping the display.
