Yintoni emisela ubungakanani benjini?

Kule mihla, indawo yoyilo lwemoto yokuqhuba kuyilo lwemoto yamandla entsha ilinganiselwe, phantsi komqathango wokuhlangana nendawo yokubeka isithuthi, kodwa kunye nenkqubo yolawulo lwemoto ebanziukujikeleza kwemotoIimfuno zexesha lokuphendula, ezifuna ukhetho olufanelekileyo lomlinganiselo wedayamitha yobude bombane, udityaniswa nokukhanya kwangoku, umzila wokudityaniswa, ingqiqo kunye nokusebenza kakuhle kwe-miniaturization yemoto kubaluleke kakhulu. Ubungakanani benjini yimfuno yobukhulu obuthile, obufana "nobude" babantu, ubude be-axial yemoto L bufana "nobude" babantu, i-motor diameter D iyafana "nesangqa" sabantu, umlinganiselo wesibini. ngumlinganiselo wobude bomdayamitha, ukumisela umlinganiselo wobude bobude bemoto, kufuneka siqale simisele uthotho lweeparamitha eziphambili zemoto. Njengoko sonke sisazi, amandla emoto = isantya * torque. Umthamo kunye namandla emoto ayilobudlelwane obuthe ngqo kakhulu, i-motor ifuna ukwenza i-miniaturize, kuya kufuneka ucinge ngokunyusa amandla emveliso kwimeko yevolumu engaguqukiyo (amandla emveliso = umthwalo wemagnethi × umthwalo wombane × isantya), okuthetha ukuba umthamo unokuba mncinci kwimeko yamandla aphuma rhoqo.

Indlela yokuphucula amandla okuphuma ngokubanzi kunye nokunciphisa ilahleko phantsi kwesiseko somthamo ofanayo yeyona nto inzima yemoto ibe yincinci. Izinto ezimbini eziphambili ezichaphazela amandla okuphuma kwemoto, enye isantya, enye yitorque, imveliso yezi zimbini ziphezulu, amandla aphumayo makhulu, ukongeza kwimfuno yokuqwalasela umthwalo wombane wemoto A. (imagnethi esebenzayo yesekethe yemagnethi yemoto) kunye nomthwalo wemagnethi B (inani le-ampere-turn xa ikhoyili yenziwe amandla).

Kuphela i-motor inomthamo omkhulu wangoku okanye ophezulu wamagnetic unokusebenzisa i-motor encinci ukuvelisa i-torque enkulu, kunye ne-motor ukudlula i-current enkulu, iya kuvelisa ilahleko yokumelana kunye nobushushu, okuya kukhokelela kwiindleko ezingalinganiyo kunye nenzuzo, ngoko ke inokuphucula kuphela ukuxinana kwamagnetic, oko kukuthi, ukunyanzeliswa kwamagnetic. Amandla emoto yemagnethi esisigxina ahanjiswa ngomsantsa womoya phakathi kwe-fixed kunye ne-rotor ngendlela yamandla ombane, ngoko ke uyilo lwemoto kufuneka lujongane noxinzelelo olwahlukeneyo lwemagnethi, njengoxinzelelo lwemagnethi yomoya, uxinaniso lwemagnethi yamazinyo, ingxinano yedyokhwe, umndilili. Uxinaniso lwemagnethi, kunye nobuninzi bemagnethi.
Ukwandisa umthwalo wamagnetic B, kuyimfuneko ukuba ube nezinto ezilungileyo zokuqhuba kazibuthe. Ngenxa yesiphumo sokuzalisa, ubuninzi bemagnethi kwiphepha lentsimbi lombane linokufikelela kuphela malunga ne-2T, ngenxa yobukho beendawo zokubeka izinyo, ngoko ke umsantsa womoya wemagnethi ungaphantsi kwe-2T, ngokubanzi ujikeleze i-1T, ukuze ufikelele phezulu. Uxinaniso lwemagnethi, imfuno yekhoyili ephezulu ye-electromagnetic yangoku ukuze imincili okanye imincili enemagnethi ephezulu ehlala isigxina.

Ikhoyili ye-electromagnetic ephezulu yangoku ngokwayo iya kufudumala, kukho umda wangoku, iimagnethi ezisisigxina ezihlala zihleli ziziintsimbi ezinqabileyo, zibiza kakhulu, ngoko ke umthwalo wemagnethi unomda.

Ukongeza, kukho indlela yokunciphisa umthamo wemoto, oko kukuthi, kwimeko yamandla angaguqukiyo, ukuba ufuna ukunciphisa umthamo wemoto, unokunciphisa i-torque yemoto, eya kwandisa isantya semoto. kwaye ekugqibeleni usebenzise umnciphisi ukufezekisa injongo yokunciphisa umthamo.
