Research and development of the high-speed solenoid valve electromagnet

Aiming at the rapid response key factor of high-speed solenoid valve, two aspects of size of electromagnet and electromagnetic force and coil driver were stated. That the elements of shape of electromagnet core and working air gap related to coil position, the size of working air gap, ampere-turns and circular iron core area could affect electromagnetic force were mainly analyzed. Secondly, three kinds of drive circuit were elaborated in terms of making a comparison to three coil drive circuit can influence electromagnet response. And then the relation between all elements and the size of electromagnetic force, the character of three kinds of Coil driver cuit and electromagnet were digitally simulated with Ansoft Maxwell soft well. Finally, optimum proposal for the development of electromagnet was put forwarded. The results indicate that the proposal is beneficial to quick response for high speed solenoid valve.
