Electromagnetic linear actuator

Abstract

An electromagnetic linear actuator is disclosed that is capable of providing a large driving force adequately used for a high-voltage circuit breaker due to simplified structure and reduced manufacturing cost, the actuator comprising: stators each facing the other about an axle; a mover disposed with a moving core and a moving coil wrapping the moving core to magnetize the moving core during conduction, and capable of linearly and axially moving an interior of the stator; and permanent magnets, one facing the other, and fixedly mounted on both inner walls of the stator for providing a Lorentz force and reluctance force to the moving coil for movement when a current flows in the moving coil of the mover, and for providing a holding force to the mover for holding a position when the electric conduction to the moving coil of the mover is interrupted.
