The　breaking　and　closing　operation　process　of　bi-stable　permanent　magnetic　actuator　(BPMA)　is　flexible　and　controllable,　and　can　achieve　the　permanent　magnet　locking　effect　at　the　steady-state　position.　However,　during　its　operation,　the　breaking　and　closing　air　gap　electromagnetic　and　permanent　magnet　flux　linkage　are　coupled,　which　will　affect　the　action　characteristics　of　the　moving　core.　Therefore,　this　article　constructs　the　voltage　balance　equation　of　the　breaking　and　closing　coils　through　the　equivalent　circuit　of　coil　decoupling,　and　analyzes　the　parameters　that　affect　the　coupling　phenomenon;　Design　a　current　closed-loop　to　control　the　actuator.　Through　co-simulation　of　LabVIEW　and　Multisim,　analyze　the　influence　of　the　electromotive　force　induced　by　the　coupling　phenomenon　at　each　stage　of　the　breaking　and　closing　process,　explore　the　mechanism　of　the　coupling　phenomenon,　and　the　impact　of　the　coupling　effect　on　the　action　process;　Finally,　experimental　waveforms　were　obtained　through　an　embedded　control　system,　and　the　accuracy　of　the　simulation　was　verified　by　comparing　the　simulated　waveforms.　This　indicates　the　reliability　of　the　coupling　phenomenon　analysis　through　simulation.　©　Beijing　Paike　Culture　Commu.　Co.,　Ltd.　2024.
