Ezi parameters zilinganisiweyo ngokulandelelanayo zimele izakhono ezahlukeneyo zemoto.

Kwipleyiti yegama leimveliso yemoto, iiparameter ezininzi ezibalulekileyo ezifana namandla alinganisiweyo, i-voltage elinganisiweyo, i-current rated kunye ne-frequency elinganisiweyo yemoto ziya kucaciswa. Phakathi kweeparameter ezininzi ezilinganisiweyo, ziiparameter ezisisiseko ezisekelwe kumandla alinganisiweyo njengesakhelo esisisiseko; kwi-frequency yamandla Imoto, xa i-voltage elinganisiweyo, i-current rated kunye ne-frequency elinganisiweyo yemoto ihlangabezana neemfuno, imoto inokusebenza ngokuqhelekileyo. Phantsi kwesimo esilinganisiweyo esihambelanayo, imoto inokukhupha i-torque elinganisiweyo, ebonakaliswa ngokukodwa kubuchule bemoto bokutsala umthwalo. Kwiimoto ze-frequency eziguquguqukayo, ngenxa yeempawu ezitshintshayo ze-frequency yamandla okufaka, imo yokusebenza iyonke yemoto ilawulwa phantsi kwe-torque engapheliyo kunye neemeko zokusebenza ze-frequency eqhubekayo ukuqinisekisa ukhuseleko lokusebenza kwemoto. Ngokushwankathela nje ezi parameter ezilinganisiweyo zemoto, ngokusisiseko zinokwahlulwa zibe ngamacandelo amabini: ukhuseleko loomatshini kunye nokhuseleko lombane.

Ukhuseleko loomatshini lwemoto luphawulwa yi-torque elinganisiweyo. Ubungakanani be-torque yemoto buchaphazela ngokuthe ngqo imeko yenkqubo yokuthwala kunye ne-shaft ejikelezayo. Umzekelo, kwimoto enzima, kufuneka ifaniswe nee-bearings ezinokuthwala umthwalo omkhulu; xa i-torque yemoto inkulu, iya kuba nemiphumo emibi kumgangatho wokusebenza kwe-bearings; kwangaxeshanye, ukongeza kumgangatho wokusebenza kwenkqubo yokuthwala, i-torque enkulu inokubangela ukuba i-shaft iphambuke okanye iqhekeke, ngakumbi kwi-shafts ezidibeneyo, inqanaba lemiphumo emibi liya kuba likhulu.

Ukhuseleko lombane lwemoto lubonakaliswa yi-voltage elinganisiweyo kunye ne-current elinganisiweyo. Xa i-voltage elinganisiweyo inkulu, i-voltage ye-inter-turn ye-winding iyanda, nto leyo ekhokelela ekungathembeki kwe-inter-turn insulation; xa i-motor current inkulu kakhulu, i-winding iya kuchaphazela ngqo i-current density ngenxa ye-large current factor, kwaye i-large current density iya kubangela ukuba umqhubi ashushu kakhulu, kwaye isiphumo sokugqibela kukunyuka kobushushu, okusongela ngakumbi ukuthembeka kombane kwemoto.

Ngoko ke, nokuba yimoto ye-frequency yorhwebo okanye yimoto ye-frequency eguquguqukayo, ukhuseleko lokusebenza kwayo lujikeleze ukhuseleko loomatshini kunye nokhuseleko lombane. Nakuphi na ukuphambuka kwiimeko ezilinganisiweyo kuya kuba nemiphumo emibi kwimoto.
