Lamapharamitha alinganiselwe amelela ngokulandelana amandla ahlukile wemoto.

Kwi-neplate yeUmkhiqizo we-motor, amapharamitha amaningana abalulekile njengamandla alinganiselwe, alinganiselwe kagesi, ulinganiselwe wamanje futhi alinganiselwe imvamisa yemoto izocaciswa. Phakathi kwamapharamitha alinganiselwe ambalwa, angamapharamitha ayisisekelo asuselwa kumandla alinganiselwe njengohlaka oluyisisekelo; Ukuze uthole amandla imvamisa ye-Power, lapho i-voltage ekalwe, ulinganise imvamisa yamanje futhi ekalwe yimoto ihlangabezana nezidingo, imoto ingasebenza ngokujwayelekile. Ngaphansi kombuso ohambisanayo, imoto ingakhipha i-torque ekalwe, eboniswa ngokukhethekile emandleni emoto yokudonsela umthwalo. Ukuze uthole ama-motors ajwayelekile aguqukayo, ngenxa yezimpawu eziguqukayo zemvamisa yamandla okufaka, imodi yokusebenza ephelele yemoto ilawulwa ngaphansi kwezimo ezisebenza njalo kanye nezimo zokusebenza njalo ukuze uqinisekise ukuphepha kokusebenza kwezimoto. Ngokufingqa la mapharamitha alinganiselwe emoto, angahle ahlukaniswe izingxenye ezimbili: ukuphepha kwemishini nokuphepha kukagesi.

Ukuphepha kwemishini kwemoto kubonakaliswa yi-torque ekalwe. Ubukhulu be-torque yemoto buthinta ngqo isimo sohlelo lokuthwala kanye nomgodi ojikelezayo. Isibonelo, ngemoto esindayo esebenza kanzima, kufanele ifaniswe namabhere angaphatha umthwalo omkhulu; Lapho i-motor torque inkulu, izoba nemiphumela emibi ngekhwalithi yokusebenza yomthwane; Ngasikhathi sinye, ngaphezu kwekhwalithi yokusebenza yohlelo lokuthwala, i-torque enkulu ingadala ukuthi ishafqu ibe yiphutha noma iphule, ikakhulukazi imisele ye-welded, izinga lemiphumela emibi lizoba likhulu abanye.

Ukuphepha kukagesi kwe-motor kubonakaliswa yi-voltage ekalwe futhi kulinganiswe njengamanje. Lapho i-voltage evunyelwe inkulu, i-voltage eguqukayo yomoya ovuthayo inyuka, okuholela ngqo ekungeneni kokufakwa ngaphakathi kokushintshana; Lapho i-motor yamanje inkulu kakhulu, i-winding izokuthinta ngqo ngobunzima obukhona ngenxa yento enkulu yamanje, futhi ubuningi obukhulu buzokwenza ukuthi umqhubi wamanje uzokuvuselela amandla kagesi, okubuye kusongele ukwethenjwa kukagesi, okubuye kusongela ukuthembeka kukagesi, okubuye kusongela ukuthembeka kukagesi kwemoto.

Ngakho-ke, noma ngabe kuyimvamisa ye-Frequenction motor noma i-frecial frequency motor, ukuphepha kokusebenza kwayo kugxile ngokuphepha kwemishini nokuphepha kukagesi. Noma yikuphi ukuphambuka ezimeni ezilinganiselwe kuzoba nemiphumela emibi emotweni.
