WO2008135670A9 BISTABLE ELECTROMAGNETIC ACTUATOR, CONTROL CIRCUIT FOR A DUAL COIL ELECTROMAGNETIC ACTUATOR, AND DUAL COIL ELECTROMAGNETIC ACTUATOR INCLUDING SUCH CONTROL CIRCUIT 审中-公开
双电磁致动器，用于双线圈电磁致动器的控制电路和包括这种控制电路的双线圈电磁致动器

BISTABLE ELECTROMAGNETIC ACTUATOR, CONTROL CIRCUIT FOR A DUAL COIL ELECTROMAGNETIC ACTUATOR, AND DUAL COIL ELECTROMAGNETIC ACTUATOR INCLUDING SUCH CONTROL CIRCUIT
Abstract:
The invention relates to a bistable electromagnetic actuator that comprises a magnetic circuit (12) including a magnetic yoke (20) in which a shunt (26) extends perpendicularly to a longitudinal axis (Y) of said yoke, and including a permanent magnet (14) provided between the first face (22) of the yoke and the shunt (26). A mobile core (16) is mounted so as to be capable of axial sliding between a latching position and a release position. A coil (30, 30A, 30B) extending between the shunt (26) and a second face (24) of the yoke generates a first control magnetic flow (fC1 ) for moving the mobile yoke (16) from the release position (PD) to the latching position (PA). A second control magnetic flow (fC2 ) allows the movement of the yoke (16) from the latching position to the release position (PD) under the action of a return spring (36, 37).
Abstract(Chinese):

本发明涉及一种双稳态电磁致动器，其包括磁路（12），磁路（12）包括磁轭（20），其中分流器（26）垂直于所述磁轭的纵向轴线（Y）延伸，并且包括永磁体 ）设置在轭的第一面（22）和分路（26）之间。 移动芯（16）安装成能够在闩锁位置和释放位置之间轴向滑动。 在轭的分流器（26）和第二面（24）之间延伸的线圈（30,30A，30B）产生用于使可动轭（16）从释放位置（PD）移动的第一控制磁流（fC1） 到锁定位置（PA）。 第二控制磁流（fC2）允许轭（16）在复位弹簧（36,37）的作用下从锁定位置移动到释放位置（PD）。
