Abstract

The objective of the project is to create a new actuation method for electromagnetic micro relays. This actuation method wilJ be demonstrated using a large scale model of a relay.In a conventional relay system, the cantilever will be energized by the coil to tum on another separate circuit. This coil must be supplied by a continuous current all along when it is turned on. The magnetic field should be strong enough to pull the cantilever down to touch the lower contact. This method will consume high amount of current to maintain the energized circuit.Theoretically, by applying small magnetic field from the coil plus with repetitive pulse signal to energize the relay would reduce the amount of power consumed. This repetitive pulse signal will be adjusted according to the cantilever's natural frequency to make it wobbles. Once the cantilever starts swinging, more and more pulse that matches its resonance frequency will enhance the wobble and finally the end contact of the cantilever touches the connector thus completing the circuit. The pulse triggering point plays an important role. The diagram below shows the triggering point.
