(1) Proportional electromagnet kulakwitsa ① Chifukwa cha pulagi msonkhano mawaya socket (m'munsi) kukalamba, kukhudzana osauka ndi electromagnet lead kuwotcherera ndi zifukwa zina, chifukwa proportional maginito maginito sangathe kugwira ntchito (sakhoza kudutsa panopa). Panthawiyi, mita ingagwiritsidwe ntchito kuti izindikire, ngati kukana kumapezeka kuti sikungatheke, mukhoza kubwezeretsanso kutsogolera, kukonza socket ndi pulagi mwamphamvu. (2) Kulephera kwa zigawo za koyilo kumaphatikizapo kukalamba kwa koyilo, kuyatsa koyilo, kusweka kwa waya wamkati ndi kukwera kotentha kwa koyilo. Kukwera kwa kutentha kwa koyilo ndikokulira kwambiri kuti kupangitse mphamvu yamagetsi yofananirako sikokwanira, ndipo zina zonse zipangitsa kuti maginito amagetsi asamagwire ntchito. Pakuti koyilo kutentha kukwera ndi lalikulu kwambiri, mukhoza kuona ngati panopa ndi lalikulu kwambiri, ngati koyilo enameled waya kutchinjiriza ndi osauka, ngati valavu pachimake anamamatira chifukwa dothi, etc., mmodzimmodzi kupeza chifukwa ndi kuthetsa izo; Kwa waya wosweka, kuwotcha ndi zochitika zina, koyiloyo iyenera kusinthidwa. Cholakwika chachikulu cha gulu la zida ndi chakuti zida zankhondo ndi zotsutsana zomwe zimapangidwa ndi maginito owongolera manja pakugwiritsa ntchito, zomwe zimapangitsa kuti valavu ichuluke. Palinso kankhira ndodo kalozera ndodo ndi armature osiyana mtima, zidzachititsanso kuwonjezeka mphamvu hysteresis, ayenera kuchotsedwa. ④ Chifukwa kuwotcherera sikuli kolimba, kapena kuwotcherera kwa manja a kalozera wa maginito kumasweka chifukwa cha mphamvu ya valavu yomwe ikugwiritsidwa ntchito, kotero kuti maginito amagetsi amataya ntchito yake.
