Utility
Electromagnetic actuator
26 Jan 21
An electromagnetic actuator in which magnetic force from a permanent magnet causes a stator core and a first plunger to attract each other, and electromagnetic force generated by energizing an electromagnetic coil causes a mover to resist against the magnetic force from the permanent magnet to move in an axial direction separating from a front end portion of the stator core, wherein a ring member provided on the mover is inserted in the axial direction into a hole portion provided in a bottom wall member of a yoke, and an overlap size between the ring member and the bottom wall member is increased when the mover moves relative to the stator core in a separating direction, so that a magnetism transmission quantity from the permanent magnet passing through an overlap portion between the ring member and the bottom wall member is inhibited from being reduced.
