Permanent magnet AC contactor works

Is the use of permanent magnet AC contactor poles repel each other, opposite sex attraction principle, permanent  power transformers  mechanism to replace the traditional magnet drive mechanism and the formation of a micro-power contacts. Linkage mechanism mounted on the contactor of the permanent magnet fixed polarity, and curing the contactor end

The variable base soft magnetic polar interaction, so as to pull, to maintain and release purposes. The variable electric transformer is cured together with an electronic module generates a dozen to two dozen milliseconds forward and reverse pulse current, and to produce different polarities. According to the site

Need, with the control electronics module to control the release of the set voltage value, can also be a delay before issuing reverse pulse current to reach the low-voltage power-off delay release delayed release or purpose to control the motor from Akira power grid and a jump stop, so as to maintain the stability of the production system
