This　paper　proposes　a　co-simulation　method　for　intelligent　monostable　permanent　magnetic　(PM)　contactor.　Firstly,　aiming　at　the　application　defects　of　the　equivalent　circuit　of　the　traditional　electromagnetic　contactor　in　the　holding　and　breaking　process　of　the　PM　contactor,　an　equivalent　circuit　model　of　the　PM　contactor　suitable　for　the　whole　process　is　proposed　by　considering　the　electromagnetic　flux　linkage　and　PM　flux　linkage　separately.　Then,　the　finite　element　simulation　combined　with　the　equivalent　magnetic　circuit　is　used　to　deal　with　the　mutual　coupling　between　PM　field　and　electromagnetic　field,　and　the　calculation　method　of　each　element　parameter　in　the　equivalent　circuit　model　is　given.　Finally,　combining　the　breaking　and　closing　control　strategy　and　the　dynamic　model　of　the　PM　contactor,　a　co-simulation　method　of　the　monostable　intelligent　PM　contactor　is　constructed,　and　its　effectiveness　is　verified　through　experiments.　The　simulation　method　reflects　the　interaction　between　electromagnetic　field　and　PM　field　in　detail　in　the　whole　dynamic　process　of　the　PM　contactor,　so　it　can　lay　a　foundation　for　the　design　of　high-performance　optimal　control　based　on　the　close　coordination　of　electromagnetic　force,　permanent　force　and　spring　reaction　force.　©2023　Chin.Soc.for　Elec.Eng.
