Ubudlelwane phakathi kwamandla emoto, isantya kunye netorque

Ingqikelelo yamandla ngumsebenzi owenziwe ngexesha leyunithi.Ngaphantsi kwemeko yamandla athile, isantya esiphezulu, i-torque ephantsi, kwaye ngokuphambeneyo.Ngokomzekelo, i-motor ye-1.5kw efanayo, i-torque yokuphuma kwinqanaba le-6 liphezulu kunelo nqanaba lesine.Ifomula ethi M=9550P/n ingasetyenziselwa ukubala ngokurhabaxa.

Kwiimoto ze-AC: i-torque elinganisiweyo = 9550 * amandla alinganisiweyo / isantya esilinganiselwe;kwiinjini zeDC, kunzima kakhulu kuba zininzi kakhulu iintlobo.Mhlawumbi isantya esijikelezayo silingana nombane we-armature kunye nokulinganisa ngokuphambeneyo nombane wokuvuselela.I-Torque ihambelana nokuguquguquka kwentsimi kunye ne-armature current.

• Ukulungelelanisa i-voltage ye-armature kulawulo lwesantya se-DC lololawulo lwesantya se-torque rhoqo (i-torque ye-motor ayitshintshanga ngokusisiseko)
• Xa uhlengahlengisa i-voltage yokuvuselela, yeyolawulo lwesantya samandla rhoqo (amandla okukhutshwa kwemoto ngokusisiseko akatshintshwanga)

I-T = 9.55 * P / N, i-T ye-torque ephumayo, amandla e-P, isantya se-N, umthwalo we-motor uhlukaniswe ngamandla angapheliyo kunye ne-torque eguquguqukayo, i-torque eqhubekayo, i-T ihlala ingatshintshi, emva koko i-P kunye ne-N ihambelana.Umthwalo ungamandla angatshintshiyo, emva koko i-T kunye ne-N zihambelana ngokungafaniyo.

Torque=9550*imveliso yamandla/isantya semveliso

Amandla (Watts) = Isantya (Rad/sec) x Torque (Nm)

Enyanisweni, akukho nto yokuxoxa, kukho ifomula P = Tn / 9.75.Iyunithi ye-T yi-kg·cm, kunye ne-torque=9550*imveliso yamandla/isantya sokuphuma.

Amandla aqinisekile, isantya sikhawuleza, kwaye i-torque incinci.Ngokuqhelekileyo, xa i-torque enkulu ifunwa, ngaphezu kwemoto enamandla amakhulu, i-miniderer eyongezelelweyo iyafuneka.Inokuqondwa ngolu hlobo ukuba xa amandla P ehlala engatshintshi, isantya esiphezulu, i-torque encinci yokuphuma.

Singayibala ngolu hlobo: ukuba uyayazi i-torque resistance T2 yezixhobo, isantya esilinganisiweyo se-n1 se-motor, i-speed n2 ye-shaft ephumayo, kunye nenkqubo yezixhobo zokuqhuba i-f1 (le f1 inokuchazwa ngokweyona nto Imeko yokusebenza kwisiza, uninzi lwasekhaya lungaphezulu kwe-1.5 ) kunye namandla factor m yemoto (oko kukuthi, umlinganiselo wamandla asebenzayo ukuya kumandla apheleleyo, anokuqondwa njengesantya esipheleleyo sokujikeleza kwemoto, ngokubanzi. ku-0.85), sibala amandla ayo e-motor P1N.P1N>=(T2*n1)*f1/(9550*(n1/n2)*m) ukufumana amandla emoto ofuna ukuyikhetha ngeli xesha.
Umzekelo: i-torque efunwa sisixhobo esiqhutywayo yile: 500N.M, umsebenzi ziiyure ezi-6 / imini, kunye ne-coefficient yesixhobo esiqhutywayo f1 = 1 inokukhethwa kunye nomthwalo olinganayo, i-reducer ifuna ukufakwa kwe-flange, kunye nesantya semveliso. n2=1.9r/min Emva koko umlinganiselo:
