Kuba amandla afanayo we3 isigaba motor, xa i-torque ye-motor incinci, isantya esihambelanayo kufuneka sikhawuleze; Xa i-torque ye-motor inkulu, isantya esihambelanayo siyacotha. Ngokubhekiselele kubudlelwane phakathi kwezi zibini, besisoloko sinxibelelana nawe ngokwethiyori ngeefomula ezithile. Ngobudlelwane bobungakanani obuphakathi kwezi zimbini, sinokuyiqonda ngcono i-motor yamandla efanayo kunye ne-voltage elinganisiweyo efanayo kunye nobude obuphakathi, kunye ne-torque yemoto enesantya esisezantsi esinepali ezininzi inkulu kunaleyo yemoto enesantya esisezantsi. Ngamanye amazwi, phantsi kweemeko zamandla ezifanayo, iInjini enesantya esiphezuluinetorque encinci kodwa ibaleka ngokukhawuleza, ngelixa i-motor enesantya esisezantsi ibaleka kancinci kodwa inomthamo owomeleleyo wokutsala umthwalo. Kulula ukuqonda ukusebenza kwamandla rhoqo kwemotor frequency frequency ngobu budlelwane.
Ke ngoko, kubudlelwane phakathi kwetorque kunye nesantya, akukho mqobo wemeko, akukho budlelwane buthelekisekayo phakathi kwezi zimbini, phantsi kweemeko ezifanayo zetorque, ukukhawuleza kwesantya samandla emoto ahambelanayo sikhulu, ngokufanayo, phantsi kweemeko zesantya esifanayo, kokukhona amandla ahambelanayo makhulu. Kwinkqubo yokukhetha i-motor, kufuneka sikhethe iimveliso zeemoto ezifanelekileyo ngokwemiqathango ethile yokusebenza, okokuqala, kufuneka siqonde ngokupheleleyo ubungakanani bomthwalo otsalayo, ohambelana ngokuthe ngqo ne-torque index ye-motor; Okwesibini, kufuneka kucace ukuba isantya sokusebenza kwesixhobo esirhuqwayo, esihambelana nesantya semoto; Ezi zalathisi zibini ngokusisiseko zimisela amandla kunye nenani leepali zemoto.
Kwidatha ye-motor nameplate, amandla kunye nesantya ziphawulwe ngokuthe ngqo, kwaye i-torque inokufunyanwa ngokubala okulula.
