| 摘要 |
<p>The present invention relates to a monophase electromagnetic actuator comprising at least a first ferromagnetic part (10) integral with a member movable along a direction Y, and a second fixed stator part (1, 2, 3) made of soft magnetic material and comprising at least one electric coil (15), said actuator comprising a thin transversely magnetized magnet (16), the fixed stator part and the movable ferromagnetic part (10) defining between each other at least two air gaps (13, 14) arranged symetrically with respect to the medial plane perpendicular to the axis of displacement Y of the movable member (10) and passing through the middle of the permanent magnet (16), the length of the movable ferromagnetic part (10) being substantially equal to the length of the permanent magnet (16).</p> |
