Ngamandla afanayo we3 isigaba motor, lapho i-torque ye-motor incane, ijubane elihambisanayo kufanele libe ngokushesha; Lapho i-torque ye-motor inkulu, ijubane elihambisanayo lihamba kancane. Mayelana nobudlelwano phakathi kwalokhu okubili, besivame ukuxhumana nawe ngethiyori ngamafomula athile. Ngobudlelwane bosayizi phakathi kwalokhu okubili, singayiqonda kangcono injini yamandla efanayo enevoltheji elinganiselwe efanayo kanye nokuphakama okufanayo kwesikhungo, futhi i-torque yenjini enesivinini esiphansi enezigxobo eziningi inkulu kunaleyo yenjini enesivinini esiphansi. Ngamanye amazwi, ngaphansi kwezimo zamandla ezifanayo, iinjini enesivinini esikhuluinetorque encane kodwa igijima ngokushesha, kuyilapho injini enesivinini esiphansi igijima kancane kodwa inamandla okudonsa amandla. Kulula ukuqonda ukusebenza kwamandla okungaguquki kwe-variable frequency motor ngalobu budlelwano.
Ngakho-ke, ebuhlotsheni phakathi kwe-torque nesivinini, asikho isidingo sombandela, abukho ubuhlobo bokuqhathaniswa kosayizi phakathi kwalokhu kokubili, ngaphansi kwezimo zetorque ezifanayo, lapho ijubane lamandla emoto ahambisanayo likhulu, ngokufanayo, ngaphansi kwezimo zejubane elifanayo, amandla amakhulu ahambisanayo makhulu. Enqubweni yokukhetha imoto, kufanele sikhethe imikhiqizo yemoto efanelekile ngokuya ngezimo ezithile zokusebenza, okokuqala, kufanele siqonde ngokugcwele usayizi womthwalo ohudulwayo, ohlobene ngqo nenkomba ye-torque yemoto; Okwesibili, kufanele kucace ukuthi isivinini sokusebenza semishini edonswayo, ehambisana nesivinini semoto; Lezi zinkomba ezimbili ngokuyisisekelo zinquma amandla kanye nenani lezigxobo zemoto.
Kudatha ye-motor nameplate, amandla nesivinini kumakwa ngokuqondile, futhi i-torque ingatholwa ngokubala okulula.
