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 phakathi kwezi zimbini, sinokuqonda ngcono i-motor yamandla efanayo kunye ne-voltage efanayo kunye nokuphakama kwendawo efanayo, kunye ne-torque ye-motor enesantya esisezantsi esine-pali ezininzi inkulu kunaleyo yesantya esiphezulu esisezantsi- i-pole motor. 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 bokuthelekisa ubungakanani phakathi kwezi zimbini, phantsi kweemeko ezifanayo zetorque, isantya samandla emoto ahambelanayo sikhulu, ngokufanayo, phantsi kwesantya esifanayo. iimeko, 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 zimisela ngokusisiseko amandla kunye nenani leepali zemoto.
Kwidatha ye-motor nameplate, amandla kunye nesantya ziphawulwe ngokuthe ngqo, kwaye i-torque inokufunyanwa ngokubala okulula.
