Njengoba i-motor current ikhula, ingabe i-torque nayo izokhula?

I-torque iyinkomba ebalulekile yokusebenza kwemikhiqizo yezimoto, ekhombisa ngqo amandla emoto ukushayela umthwalo.Emikhiqizweni yezimoto, i-torque yokuqala, i-torque elinganiselwe kanye ne-torque ephezulu ibonisa ikhono lemoto ezifundeni ezahlukene.Ama-torque ahlukene ahambisana nawo Kuphinde kube nomehluko omkhulu ngobukhulu bamanje, futhi ubudlelwano phakathi kobukhulu bamanje kanye ne-torque bubuye buhluke ngaphansi kwezimo zokungalayishi nokulayisha kwemoto.

I-torque ekhiqizwa injini ngesikhathi lapho i-voltage isetshenziswa emoteni lapho imile ibizwa ngokuthi i-torque yokuqala.Ubukhulu be-torque yokuqala bulingana nesikwele se-voltage, bukhuphuka ngokunyuka kokumelana ne-rotor, futhi buhlobene nokusabela kokuvuza kwemoto.Ngokuvamile, ngaphansi kwesimo se-voltage egcwele, i-torque yokuqala esheshayo ye-AC motor asynchronous ingaphezu kwezikhathi ezingu-1.25 ze-torque elinganisiwe, kanti okwamanje okuhambisanayo kubizwa ngokuthi i-start current, okuvame ukuba izikhathi ezi-5 kuye kweziyi-7 zamanje ezilinganiselwe.

I-motor ngaphansi kwesimo sokusebenza esilinganiselwe ihambisana ne-torque elinganiselwe kanye nesilinganiso samanje se-motor, okuyimingcele eyinhloko ngaphansi kwezimo ezijwayelekile zokusebenza ze-motor;lapho i-motor igcwele kakhulu ngesikhathi sokusebenza, ihilela i-torque enkulu ye-motor, ekhombisa ukumelana kwe-motor Umthamo wokulayisha ngokweqile uzophinde uhambisane nomthamo omkhulu ngaphansi kwesimo se-torque ephezulu.

Ngenjini eqediwe, ubudlelwano phakathi kwetorque kagesi yemoto engavumelaniyo kanye ne-magnetic flux kanye ne-rotor current kukhonjiswe kufomula (1):

I-electromagnetic torque = njalo × i-flux kazibuthe × ingxenye esebenzayo yesigaba ngasinye samanje se-rotor… (1)

Kungabonakala kufomula (1) ukuthi i-torque kagesi ilingana ngokuqondile nomkhiqizo we-air gap flux kanye nengxenye esebenzayo ye-rotor current.I-rotor current kanye ne-stator current ngokuyisisekelo zilandela ubudlelwano besilinganiso sokuphenduka esingaguquki, okungukuthi, lapho i-flux kazibuthe ingafinyeleli ekugcwalisweni kwendawo, itorque kagesi kanye nokwamanje kuhlotshaniswa kahle.I-torque ephezulu yinani eliphakeme le-torque ye-motor.

I-torque ye-electromagnetic ephezulu ibaluleke kakhulu enjini.Lapho i-motor isebenza, uma umthwalo ukhuphuka ngokuzumayo isikhathi esifushane bese ubuyela emthwalweni ojwayelekile, inqobo nje uma itorque yokubhuleka isiyonke ingenkulu kunetorque enkulu kagesi, injini isengagijima ngokuzinza;kungenjalo, injini izoma.Kungabonakala ukuthi uma i-torque enkulu kagesi iphezulu kakhulu, amandla omthamo we-motor wesikhathi esifushane anamandla kakhulu, ngakho-ke umthamo wokugcwala kakhulu wenjini uvezwa isilinganiso setorque kagesi ephezulu kakhulu kwitorque elinganiselwe.
