Yintoni umahluko phakathi kwamandla afanayo phakathi kweemoto ezinamandla afanayo kunye ne-torque elinganisiweyo?

Kufuneka kuqatshelwe ukuba isantyainjini yombaneii-s ezinamandla afanayo zinokwahluka kakhulu ngokuxhomekeke kwiimeko zokusetyenziswa okanye izixhobo ezixhasayo. Ngendlela yomzekeliso, ii-motor ze-2P kunye ne-8P kwii-ac motor yombane yemizi-mvelisozinesantya esihambelanayo se-3000 rpm kwi-motor enezibonda ezimbini, ngelixa isantya esihambelanayo se-motor ye-8P singama-750 rpm kuphela. Injongo yengxoxo yanamhlanje kukuhlalutya ulwalamano lobungakanani beeparameter ezifanelekileyo zeimoto engenaxesha linye enamanqanaba amathathus ngamandla afanayo kodwa amanani eepali ahlukeneyo. I-voltage elinganisiweyo kunye ne-frequency elinganisiweyo ziimeko zobonelelo lwamandla okusebenza kwemoto eqhelekileyo. Ngokusekelwe kwezi meko zimbini, sihlalutya kwaye sixoxe ngobudlelwane bobungakanani bezinye iiparameter.

Ubudlelwane bobungakanani bombane olinganisiweyo: Sihlalutya ubudlelwane phakathi kwamandla okufaka kunye nevolthi elinganisiweyo, umbane olinganisiweyo, ukusebenza kakuhle kunye ne-power factor ngokusekelwe kwifomula P1=√3UIcosϕ.

Kufuneka kuqatshelwe ukuba ukusebenza kakuhle kunye namandla eemoto ezinesantya esiphantsi zincinci kakhulu, nto leyo ebangela ukuba kubekho umbane omkhulu ohambelanayo.

Ubudlelwane phakathi kwe-torque elinganisiweyo kunye nobukhulu becandelo elichaphazelekayo bulandelayo: Ngokuhambelana nolwalamano phakathi kwe-torque elinganisiweyo kunye namandla alinganisiweyo emoto, T=9.55P/n, kunokubonwa ukuba njengoko isantya sincipha phantsi kweemeko ezifanayo zemoto yamandla, i-torque ehambelanayo iyanda ngobukhulu. I-Torque ichazwa njengamandla emoto okutsala umthwalo. Iimoto ezinesantya esiphantsi zahlulwa ngokukwazi kwazo ukuhambisa i-torque ephezulu ngesantya esiphantsi. Ngokufanayo, iimoto ezinesantya esiphezulu zahlulwa nge-torque ephantsi kunye nesantya esiphezulu.

Kule datha, sinokuqinisekisa ukuba kwiimoto ezinamandla afanayo kodwa zinamanani ahlukeneyo eepali, umbane olinganisiweyo wemoto enesantya esiphantsi mkhulu kancinci kunowemoto enesantya esiphezulu. Nangona kunjalo, kukho umahluko obonakalayo kwi-torque elinganisiweyo, ehambelana ngokuphambeneyo nesantya. Oku kukwabonelela ngengqiqo yokuba kutheni ububanzi be-shaft yemoto enesantya esiphantsi bukhulu, kwaye iinkcukacha zebhereji ezihambelanayo nazo zikhulu.
