A new type of electromagnetic actuator with high holding force and extremely low consumption of electric energy is proposed and modeled. The movement of its plunger formed by a permanent magnet is controlled by short pulses of direct current together with a return spring. The paper presents the arrangement of the device and analyses its principal operation characteristics.
