Sensorless detection of free-falling state of a HDD by monitoring electromechanical signal of a spindle motor
Gunhee Jang, S.J. Park · 2005
This research proposes a sensorless detection method of a free-falling condition of a HDD before unexpected shock by monitoring the electromechanical signals of a HDD spindle motor. The electromechanically coupled simulation presents the theoretical background and the simulation result is verified by the experiment.
