Ukuma nosayizi wezikhala ze-rotor kunomthelela oqondile ekuphikisweni kwe-rotor kanye nokugeleza kokuvuza, okuzothinta ukusebenza kahle kwemoto, amandla, i-torque ephezulu, i-torque yokuqala kanye nezinye izinkomba zokusebenza. Ukusebenza okuthintekile kubaluleke kakhulu kuinjiniimikhiqizo.
Ekusebenzeni kwangempela, kuvame ukudingeka ukuyeka isidingo sezinye izakhiwo ukuze kusebenze okuthile. Isisho esidala esithi “awukwazi ukuba nekhekhe lakho bese ulidla futhi” siyafaneleka lapha. Yiqiniso, ezinye izinguquko zobuchwepheshe ezishintshayo ezintweni ezintsha kanye nezinqubo ezintsha zizophula lo mthetho okwesikhashana. Isibonelo, esigabeni sokuqala sokusetshenziswa kohlelo lokufaka i-high-voltage motor insulation olune-“mica tape ene-glue powder encane” njengento eyinhloko ehlanganiswe nobuchwepheshe obusha benqubo “yokumboza nge-vacuum pressure immersion”, yake yafinyelela umphumela “wokuba nekhekhe lakho bese ulidla futhi” maqondana nokunciphisa ukujiya kokufaka i-insulation kanye nokuthuthukisa ukumelana kwe-voltage kanye ne-corona. Kodwa-ke, ayikakwazi ukususa imingcele yemithetho futhi ihlala ibhekene nokuphikisana okunzima ukubhekana nakho noma amahloni.
1 Ibhalansi yokusebenza phakathi kokusebenza kokuqala kanye nomthamo wokulayisha ngokweqile
Ukuze kuthuthukiswe umthamo wokulayisha ngokweqile kwenjini, i-torque ephezulu idinga ukukhushulwa, ngakho-ke ukuphendula kokuvuza kwe-rotor kudingeka kuncishiswe; futhi ukuze kuhlangatshezwane nokuqala okuncane kanye ne-torque enkulu ngesikhathi senqubo yokuqala, umphumela wesikhumba se-rotor udinga ukukhushulwa ngangokunokwenzeka, kodwa ukusabela kokuvuza kwe-rotor slot kanye ne-magnetic flux kanye nokuvuza kumele kukhushulwe ngokungenakugwenywa.
2 Ibhalansi phakathi kokusebenza kahle kanye nokusebenza kokuqala
Siyazi ukuthi ukwandisa ukumelana kwe-rotor kungathuthukisa ukusebenza kokuqala kwenjini, njengokunciphisa isikhala se-rotor nokusebenzisa i-rotor yekheji eliphindwe kabili, kodwa ngenxa yokwanda kokumelana kwe-rotor kanye nomsinga wokuvuza, ukulahleka kwethusi kwe-stator kanye ne-rotor kuzokhula kakhulu, okuholela ekwehleni kokusebenza kahle.
3 Ukuhlola nokulinganisela phakathi kwe-power factor kanye nokusebenza kokuqala
Ukuze sithuthukise ukusebenza kokuqala kwemoto, sisebenzisa umphumela wesikhumba, njengokusebenzisa imigoqo emincane ejulile, imigoqo eqondile, imigoqo emise okwemimese, imigoqo ejulile noma imigoqo yekheji eliphindwe kabili ukuze kwandiswe ukumelana kwe-rotor ngesikhathi sokuqala, kodwa umthelela oqondile kakhulu ukwandisa. Ukuvuza kwesikhala se-rotor kuyancipha, ukugeleza kokuvuza kwe-rotor kuyanda, futhi ugesi ophendulayo we-rotor uyanda, okuzoholela ekwehleni kwamandla e-factor.
4 Ukuhlolwa kokusebenza kahle kanye nokulinganisa amandla kanye ne-power factor
Uma indawo yesikhala se-rotor ikhula futhi ukumelana kwehla, ukulahlekelwa kwethusi le-rotor kuzoncipha futhi ukusebenza kahle kuzokhula ngokwemvelo; noma kunjalo, ngenxa yokwehla kwendawo yokuvunyelwa kwamandla kagesi yejoka le-rotor, ukumelana kwamandla kagesi kuzokhula futhi ubuningi be-magnetic flux buzokhula, okubangela ukulahlekelwa yinsimbi kwande kanye ne-power factor yande. Ama-motor amaningi anokusebenza kahle njengomgomo wokwenza kahle azohlala enalesi simo: ukuthuthukiswa kokusebenza kahle kubalulekile ngempela, kodwa ugesi olinganisiwe mkhulu futhi i-power factor iphansi. Amakhasimende akhononda ngokuthi ama-motor asebenza kahle kakhulu awalungile njengezinjini ezivamile.
Kunezinkinga eziningi zokuzuza nokulahlekelwa ekwakhiweni kwezimoto. Lesi sihloko sibhekana nezici zangaphandle kuphela. Ukuze silinganisele lobu budlelwano bokusebenza, sidinga ukuhlola izici zangaphakathi ngokujulile futhi sisebenzise ngobuhlakani indlela yokucabanga ephindaphindayo yezinzuzo nokulahlekelwa ukuxazulula lokho okubizwa ngokuthi ukuphikisana noma ukuhlazeka.
