Igitekerezo cyibanze cyibikorwa bya moteri ya servo idafite amashanyarazi azenguruka ku mahame ya magnetisme aho nkibiti byanga kandi inkingi zinyuranye zikurura. Hariho amasoko abiri ya magnetiki aboneka muri moteri ya servo: Imashini zihoraho zisanzwe ziri kuri rotor ya moteri, hamwe na electromagnet ihagaze ikikije rotor. Electromagnet yitwa stator cyangwa moteri ihinduranya kandi igizwe nibyuma byitwa laminations, bihujwe hamwe. Ibyapa byicyuma mubisanzwe bifite "amenyo" yemerera umugozi wumuringa gukomeretsa.
Tugarutse ku mahame ya magnetisme, iyo umuyoboro umeze nkumugozi wumuringa ubumbabumbwe muri coil, hanyuma umuyoboro akongerwamo imbaraga kuburyo umuyoboro unyuramo, hashyirwaho umurima wa rukuruzi.
Uyu murima wa magneti wakozwe numuyoboro unyura mu kiyobora uzaba ufite inkingi yo mumajyaruguru na pole yepfo. Hamwe na magnetiki pole iherereye kuri stator (iyo ifite ingufu) no kuri magnesi zihoraho za rotor, nigute ushobora gukora leta yibiti bitandukanye bikurura kandi nkibiti byanga?
Urufunguzo nuguhindura ikigezweho kinyura muri electromagnet. Iyo imigezi itemba inyuze mu cyerekezo kimwe, amajyaruguru namajyepfo aremwa.
Iyo icyerekezo cyubu cyahinduwe, inkingi zirahindurwa kuburyo icyari inkingi yo mumajyaruguru ubu ni pole yepfo naho ubundi. Igishushanyo 1 gitanga ishusho yibanze yukuntu ibi bikora. Igishushanyo cya 2, ishusho ibumoso yerekana imiterere aho inkingi za rukuruzi za rotor zikururwa ninkingi zinyuranye za stator. Inkingi ya rotor, ifatanye na moteri ya moteri, izunguruka kugeza ihujwe ninkingi zinyuranye za stator. Niba byose bigumye kimwe rotor yaguma ihagaze.
Ishusho iburyo ku gishushanyo cya 2 yerekana uburyo inkingi za stator zahindutse. Ibi bizaba igihe cyose rotor pole ifashwe na stator pole ihabanye muguhindura imigendekere yimbere binyuze muri stator yihariye. Gukomeza guhindagura inkingi za stator bitera imiterere aho inkingi zihoraho za rukuruzi za rotor zihora "zirukanka" stator zihabanye bikavamo kuzenguruka guhoraho kwa rotor / moteri.
Guhinduranya inkingi za stator bizwi nko kugabanya. Igisobanuro gisanzwe cyo kugenda ni "Igikorwa cyo kuyobora imiyoboro yicyiciro gikwiye kugirango habeho moteri nziza ya moteri hamwe no kuzunguruka moteri". Nigute imiyoborere iyobowe mugihe gikwiye kugirango ikomeze kuzunguruka?
Ubuyobozi bukorwa na inverter cyangwa ikinyabiziga gikoresha moteri. Iyo ikinyabiziga gikoreshwa na moteri runaka impande ya offset igaragara muri software ya software hamwe nibindi bintu nka inductance ya moteri, kurwanya, nibindi bipimo. Igikoresho cyo gutanga ibitekerezo gikoreshwa kuri moteri (encoder, resolver, nibindi ..) itanga umwanya wa rotor shaft / magnetic pole kuri disiki.
Iyo magnetiki pole ihagaze ya rotor ihuye na offset, disike izahindura umuyaga unyura muri coil stator bityo uhindure pole ya stator kuva mumajyaruguru ugana mumajyepfo no kuva mumajyepfo ugana mumajyaruguru nkuko bigaragara mumashusho 2. Kuva kuri ibi urashobora kubona ko kureka inkingi igahuza bizahagarika moteri ya moteri, cyangwa guhindura urukurikirane bizabona uruziga ruzunguruka mu cyerekezo kimwe nundi, kandi kubihindura byihuse bituma byihuta byihuta cyangwa bitandukanye cyane no kuzenguruka buhoro buhoro.
