Manje lokhoEPUfuthiI-EMAasetshenziswa kabanzi, njengomsebenzi emkhakheni we-hydraulic, kuyadingeka ukuthi ube nokuqonda okuyisisekelo kwamamotho.

Ake sikhulume kafushane mayelana nokuqala kwamanje kwe-servo motor namuhla.

1Ingabe isiqalo semoto sikhulu noma sincane kunomsinga ojwayelekile osebenzayo?Kungani?

2Kungani injini ibambekile futhi kulula ukuyishisa?

Le mibuzo emibili engenhla empeleni ingumbuzo owodwa.Kungakhathalekile umthwalo wesistimu, isiginali yokuchezuka nezinye izizathu, ukuqala kwemoto kukhulu kakhulu,

Ake sikhulume kafushane ngenkinga yokuqalisa okwamanje kusuka ku-motor ngokwayo (hhayi ukucabangela inkinga yesiqalo esithambile).

I-rotor ye-motor (DC motor) yenziwe ngamakhoyili, futhi izintambo ze-motor zizosika imigqa yokungeniswa kazibuthe ngesikhathi senqubo yokusebenza ukuze kukhiqizwe amandla e-electromotive.

Okwamanje lapho i-motor inamandla, ngoba amandla e-electromotive akhiqizwayo awakakhiqizi, ngokomthetho ka-Ohm, isiqalo samanje ngalesi sikhathi:

IQ=E0/R

KuphiE0yikhono lekhoyili futhiRukumelana okufanayo.

Ngesikhathi senqubo yokusebenza yemoto, kucatshangwa ukuthi amandla e-electromotive eyengelweE1, leli khono livimbela ukujikeleza kwenjini, ngakho futhi liphenduka amandla e-electromotive counter, ngokomthetho ka-Ohm:

I=(E0-E1)/R

Njengoba amandla alinganayo kuyo yonke ikhoyili enciphile, lamanje emsebenzini liyancishiswa.

Ngokwesilinganiso sangempela, i-current motor general lapho iqala imayelana ne-4-7izikhathi zokusebenza okuvamile, kodwa isikhathi sokuqala sifushane kakhulu.Nge-inverter noma esinye isiqalo esithambile, umsinga osheshayo uzokwehla.

Ngokusebenzisa ukuhlaziya okungenhla, kufanele kube lula ukuqonda ukuthi kungani injini kulula ukuyishisa ngemva kokubanjwa?

Ngemuva kokuthi injini iyeke ukujikeleza ngenxa yokwehluleka komshini noma umthwalo omningi, ucingo ngeke lusasika umugqa wokungeniswa kazibuthe, futhi ngeke kube khona amandla e-counter electromotive.Ngalesi sikhathi, amandla emikhawulweni yomibili yekhoyili azohlala emakhulu kakhulu, futhi i-current ku-coil icishe ilingane ne-Uma i-current current inde kakhulu, izoshisa kakhulu futhi ibangele umonakalo emotweni.

Kulula futhi ukuyiqonda mayelana nokongiwa kwamandla.

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

F=BIL

Ngesikhathi i-motor iqala, yamanje inkulu kakhulu, amandla e-ampere nawo makhulu kakhulu ngalesi sikhathi, futhi i-torque yokuqala yekhoyili nayo inkulu kakhulu.Uma i-current ihlale inkulu kangaka, khona-ke amandla e-ampere azohlala ekhulu kakhulu, kanjalo ne-motor iphenduka ngokushesha kakhulu, noma isheshe futhi isheshe.Lokhu akunangqondo.Futhi ngalesi sikhathi, ukushisa kuzoba namandla kakhulu, futhi wonke amandla azosetshenziselwa ukushisa, ngakho kungani uyisebenzisela ukusunduza umthwalo ukwenza umsebenzi?

Uma usebenza ngokujwayelekile, ngenxa yokuba khona kwamandla e-counter electromotive, okwamanje kuzoba kuncane kakhulu ngalesi sikhathi, futhi ukushisa kuzoba kuncane kakhulu.Amandla anikezwa amandla angasetshenziswa ukwenza umsebenzi.

Njengevalve ye-servo, ngemuva kokusebenza kwe-loop evaliwe, ihlala iseduze nendawo eyiziro.Ngalesi sikhathi, i-pilot current (noma yamanje ku-valve yesiteji esisodwa) incane kakhulu.

Ngokuhlaziywa okungenhla, kulula futhi ukuqonda ukuthi kungani isivinini semoto sishesha, sibe sincane itorque?Ngoba lapho isivinini sishesha, iba nkulu amandla e-counter electromotive, iba mancane amandla ocingweni ngalesi sikhathi, namandla e-ampere aba mancane.F=BIL.
