LOW ENERGY MAGNETIC ACTUATOR |
摘要 |
<p>LOW ENERGY MAGNETIC ACTUATOR Magnetic actuator apparatus in which the armature is held in a restrained position on a magnetic core by magnetic flux whose density is cyclically varied in time, and the armature is selectively released by a bucking coil that is energized only when the armature retention flux is at low holding value. The flux source is a permanent magnet that is reciprocated or rotated to vary the armature retaining force. EN978029</p> |
