Ngoku uEPUkwayeEMAzisetyenziswa ngokubanzi nangakumbi, njengengcali kwintsimi ye-hydraulic, kuyimfuneko ukuba ube nokuqonda okusisiseko kweenjini.

Makhe sithethe ngokufutshane malunga nokuqalisa ngoku kwe-servo motor namhlanje.

1Ngaba isiqalo sangoku semoto sikhulu okanye sincinci kunomsinga oqhelekileyo osebenzayo?Ngoba?

2Kutheni le nto injini ibambekile kwaye kulula ukuyitshisa?

Le mibuzo mibini ingasentla ngumbuzo omnye.Kungakhathaliseki ukuba yintoni umthwalo wenkqubo, umqondiso wokutenxa kunye nezinye izizathu, ukuqala kwangoku kwemoto kukhulu kakhulu,

Makhe sithethe ngokufutshane malunga nengxaki yokuqalisa okwangoku ukusuka kwi-motor ngokwayo (ungacingi ngengxaki yokuqalisa okuthambileyo).

I-rotor ye-motor (i-DC motor) yenziwe ngeekhoyili, kwaye iingcingo zemoto ziya kunqumla imigca ye-magnetic induction ngexesha lenkqubo yokusebenza ukuvelisa amandla e-electromotive.

Okwangoku xa i-motor inikwe amandla, ngenxa yokuba amandla e-electromotive enyanzelwayo ayikaveliswa, ngokomthetho ka-Ohm, ukuqala okwangoku ngeli xesha kukuba:

IQ=E0/R

AphoE0yikhoyili enokubakho kwayeRluxhathiso olulinganayo.

Ngexesha lenkqubo yokusebenza kwemoto, kucingwa ukuba amandla e-electromotive anyanzelwayoE1, le nto inokuthi ithintele ukujikeleza kwemoto, ngoko ke iphinda ibe yi-counter electromotive force, ngokomthetho ka-Ohm:

I=(E0-E1)/R

Ekubeni amandla alinganayo kwi-coil ayancitshiswa, okwangoku emsebenzini kuyancipha.

Ngokomlinganiselo wangempela, umjelo wemoto jikelele xa uqala malunga ne-4-7amaxesha okokusebenza okuqhelekileyo, kodwa ixesha lokuqala lifutshane kakhulu.Ngokusebenzisa i-inverter okanye enye isiqalo esithambileyo, umsinga okhawulezayo uya kuhla.

Ngolu hlalutyo lungentla, kufuneka kube lula ukuqonda ukuba kutheni i-motor kulula ukuyitshisa emva kokuba ibambekile?

Emva kokuba i-motor iyeka ukujikeleza ngenxa yokungaphumeleli komatshini okanye umthwalo omkhulu, ucingo alusayi kuphinda lunqumle umgca wokungeniswa kwamagnetic, kwaye akuyi kubakho mandla e-electromotive counter. Ngeli xesha, amandla kuzo zombini iziphelo zekhoyili iya kuhlala ikhulu kakhulu, kwaye okwangoku kwikhoyili iphantse ilingane ne-Ukuba i-current current inde kakhulu, iya kutshisa kakhulu kwaye ibangele umonakalo kwi-motor.

Kwakhona kulula ukuyiqonda malunga nokugcinwa kwamandla.

Ukujikeleza kwekhoyili kubangelwa amandla e-Ampere kuyo.Amandla e-Ampere alingana ne:

F=BIL

Umzuzwana i-motor iqala, yangoku inkulu kakhulu, amandla e-ampere nawo makhulu kakhulu ngeli xesha, kwaye i-torque yokuqala yekhoyili nayo inkulu kakhulu.Ukuba umsinga usoloko umkhulu, ngoko amandla e-ampere aya kuhlala emkhulu kakhulu, ngokunjalo i-motor ijikeleza ngokukhawuleza, okanye ngokukhawuleza kwaye ngokukhawuleza.Oku akukho ngqiqweni.Kwaye ngeli xesha, ubushushu buya kuba namandla kakhulu, kwaye onke amandla aya kusetyenziselwa ukushisa, ngoko kutheni usebenzise ukutyhala umthwalo ukwenza umsebenzi?

Xa usebenza ngokuqhelekileyo, ngenxa yobukho be-counter electromotive force, okwangoku kuya kuba ncinane kakhulu ngeli xesha, kwaye ukushisa kuya kuba kuncinci kakhulu.Amandla anikezelwe ngumbane angasetyenziselwa ukwenza umsebenzi.

Kanye njengevalve ye-servo, emva kokusebenza kwe-loop evaliweyo, ihlala ikufuphi nendawo ye-zero. Ngeli xesha, i-pilot current (okanye i-current on the single-stage valve) incinci kakhulu.

Ngolu hlalutyo lungentla, kulula ukuqonda ukuba kutheni isantya semoto sikhawuleza, sincinci i-torque?Kuba okukhona ukukhawuleza kwesantya, kokukhona amandla ekhawuntara ekhawuntara, kokukhona abe mancinci umsinga wocingo ngeli xesha, kwaye ngokukhona abe mancinci amandla e-ampere.F=BIL.
