Actuator with permanent magnet controlled by very short current pulses

A new type of electromagnetic actuator with high holding force and extremely low consumption of electric energy is proposed and modelled. 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 arr...

Description
Summary:A new type of electromagnetic actuator with high holding force and extremely low consumption of electric energy is proposed and modelled. 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.
