This article describes an axial transient vibration and axial excitation response of a polygonal mirror scanner rotor driven by a flat-type brushless dc motor and supported by a passive thrust magnetic bearing and a radial air bearing. From results of experimental investigations, the following characteristics of the vibration have been deduced: (1) Repulsive magnetic force was induced between the rotor magnet and stator coils of the dc motor under current passage. The force caused axial static displacement and axial transient vibration. (2) Because the stiffness of the thrust magnetic bearing was small, large axial vibration took place due to the axial excitation. (3) Two types of damper were introduced to suppress the axial transient vibration and the axial excitation response; one was an eddy-current damper and the other was an air damper. It was demonstrated that the air damper was effective for reducing the axial vibration.

More about this publication?
  • The Journal of Imaging Science and Technology (JIST) is dedicated to the advancement of imaging science knowledge, the practical applications of such knowledge, and how imaging science relates to other fields of study. The pages of this journal are open to reports of new theoretical or experimental results, and to comprehensive reviews. Only original manuscripts that have not been previously published, nor currently submitted for publication elsewhere, should be submitted.

    IS&T's JIST-first publication option allows authors wishing to present their work at conferences, but have a journal citation for their paper, to submit a paper to JIST that follows the same rigorous peer-review vetting and publication process as traditional JIST articles, but with the benefit of a condensed time-to-publication time frame and guaranteed conference presentation slot.

    Please note: For purposes of its Digital Library content, IS&T defines Open Access as papers that will be downloadable in their entirety for free in perpetuity. Copyright restrictions on papers vary; see individual paper for details.
