Abstract: Divergent flux path magnetic actuation is a technique employed to move and magnetically hold an armature in electromechanical actuator devices. These actuators are typically used for linear and reciprocating application with a shaft firmly fixed to the armature to convey movement and forces. By incorporating a bearing in the armature about the shaft, rotation can also be conveyed. Further these actuators are more adaptable to energy saving applications than conventional solenoids, specifically when the control coils are parallel connected to reduce the input voltage from a power source and electrically pulsed activated from a capacitor to reduce the power drain from the power source. Thus a divergent flux path magnetic actuators with reciprocating and rotatable shaft can be used for multipurpose applications and be adapted to a variety of devices for energy savings over convention solenoids.

A magnetic circuit having second pole pieces located between the first pole pieces and the ferromagnetic target controls the flux directed from the first pole pieces to the ferromagnetic target.
