Electromagnetic actuator. |
摘要 |
<p>An electromagnetic actuator comprises a yoke (18) of a material having a low magnetic remanence, and a rare earth permanent magnet (24) in series with said yoke (18), providing a magnetic circuit having no flux gap. A coil (28) can induce in the yoke (18) a flux which is opposed to that from the permanent magnet (24), and an armature (26) which is responsive to the combined flux from said permanent magnet (24) and said coil (28).</p> |
