NonehoEPUnaEMAni byinshi kandi bikoreshwa cyane, nkumwitozo mu murima wa hydraulic, ni ngombwa kugira ubumenyi bwibanze kuri moteri.

Reka tuganire muri make kubyerekeranye no gutangira moteri ya servo uyumunsi.

1Ese intangiriro yo gutangira moteri nini cyangwa ntoya kuruta imikorere isanzwe ikora?Kubera iki?

2Kuki moteri ifashe kandi byoroshye gutwika?

Ibibazo bibiri byavuzwe haruguru mubyukuri nikibazo kimwe.Bititaye kumikorere ya sisitemu, ibimenyetso byo gutandukana nizindi mpamvu, itangira rya moteri nini cyane,

Reka tuvuge muri make ikibazo cyo gutangira amashanyarazi kuva moteri ubwayo (tutirengagije ikibazo cyo gutangira byoroshye).

Rotor ya moteri (moteri ya DC) ikozwe muri coil, kandi insinga za moteri zizagabanya imirongo ya magnetiki induction mugihe cyakazi kugirango itange ingufu za electronique.

Kuri ubu moteri ifite ingufu, kubera ko ingufu za electromotive zatewe zitarabyara, nkuko amategeko ya Ohm abiteganya, icyatangiye muri iki gihe ni:

IQ=E0 / R.

AhoE0ni coil ubushobozi kandiRni ukurwanya.

Mugihe cyimikorere ya moteri, ukeka ko ingufu za electromotive ariE1, ubwo bushobozi bubuza kuzenguruka moteri, bityo nayo ihinduka imbaraga za compte electromotive, nkuko amategeko ya Ohm abiteganya:

I=(E0-E1) / R.

Kubera ko ubushobozi buhwanye na coil bwagabanutse, ikigezweho kumurimo kiragabanuka.

Ukurikije ibipimo bifatika, ikigezweho cya moteri rusange mugihe utangiye ni 4-7inshuro ibyo gukora bisanzwe, ariko igihe cyo gutangira ni kigufi cyane.Binyuze muri inverter cyangwa ibindi byoroshye gutangira, ako kanya ako kanya kazagabanuka.

Binyuze mu isesengura ryavuzwe haruguru, byakagombye kuba byoroshye kumva impamvu moteri yoroshye gutwika nyuma yo gufatwa?

Nyuma yuko moteri ihagaritse kuzunguruka kubera kunanirwa kwa mashini cyangwa umutwaro mwinshi, insinga ntizongera guca umurongo wa induction, kandi ntihazabaho ingufu za electronique.Muri iki gihe, ubushobozi ku mpande zombi za coil bizahora ari binini cyane, kandi umuyaga uri kuri coil ugereranije hafi Niba Umuyoboro utangiye ari muremure cyane, bizashyuha cyane kandi byangiza moteri.

Biroroshye kandi kubyumva mubijyanye no kubungabunga ingufu.

Kuzunguruka kwa coil biterwa nimbaraga za Ampere kuri yo.Imbaraga za Ampere zingana na:

F = BIL

Mugihe moteri itangiye, ikigezweho ni kinini cyane, imbaraga za ampere nazo nini cyane muriki gihe, kandi itara ryo gutangira coil naryo rinini cyane.Niba ikigezweho ari kinini cyane, noneho imbaraga za ampere zizahora ari nini cyane, niko moteri izunguruka vuba cyane, cyangwa ndetse byihuse kandi byihuse.Ibi ntabwo bifite ishingiro.Muri iki gihe, ubushyuhe buzaba bukomeye cyane, kandi imbaraga zose zizakoreshwa mubushuhe, none kuki ukoresha kugirango usunike umutwaro gukora akazi?

Iyo ukora bisanzwe, bitewe nuko hariho imbaraga za compte electromotive, ikizaba kizaba gito cyane muriki gihe, kandi ubushyuhe buzaba buto cyane.Ingufu zitangwa n'amashanyarazi zirashobora gukoreshwa mugukora akazi.

Nka servo valve, nyuma yo gufunga-loop ibikorwa, burigihe iba hafi ya zeru.Muri iki gihe, icyerekezo cyindege (cyangwa ikigezweho kumurongo umwe wa valve) ni gito cyane.

Binyuze mu isesengura ryavuzwe haruguru, biroroshye kandi kumva impamvu umuvuduko wa moteri wihuta, niko torque iba nto?Kuberako umuvuduko wihuta, niko imbaraga za compte electromotive, niko bigenda bigabanuka muri wire muri iki gihe, kandi imbaraga za ampere ntoya.F = BIL.
