Ubudlelwano phakathi kwamandla emoto, isivinini kanye netorque

Umqondo wamandla umsebenzi owenziwa ngesikhathi seyunithi.Ngaphansi kwesimo samandla athile, ijubane liyaphakama, itorque iyancipha, futhi ngokuphambene nalokho.Isibonelo, injini ye-1.5kw efanayo, i-torque ephumayo yesiteji sesi-6 iphakeme kunaleyo yesiteji sesi-4.Ifomula ethi M=9550P/n ingaphinda isetshenziselwe ukubala okunzima.

Kumamotho e-AC: i-torque elinganiselwe = 9550* amandla alinganiselwe / isivinini esilinganiselwe; kuma-DC motors, kuba nzima kakhulu ngoba kunezinhlobo eziningi kakhulu.Mhlawumbe isivinini sokuzungeza silingana ne-voltage ye-armature futhi silinganisa ngokuphambene ne-voltage evusa amadlingozi.I-torque ilingana nokuguquguquka kwenkundla kanye ne-armature current.

• Ukulungisa i-voltage ye-armature kumthethonqubo wejubane we-DC kungokulawulwa njalo kwejubane le-torque (i-torque ephumayo yemoto empeleni ayishintshile)
• Lapho ulungisa i-voltage evusa amadlingozi, ingeyokulawulwa kwejubane lamandla njalo (amandla okukhiphayo emoto empeleni awashintshile)

I-T = 9.55 * P/N, i-torque ye-T, amandla we-P, isivinini se-N, umthwalo we-motor uhlukaniswe ngamandla angashintshi kanye ne-torque eguquguqukayo, i-torque engaguquki, i-T ihlala ingashintshiwe, bese u-P no-N belingana.Umthwalo ungamandla angashintshi, bese kuthi u-T no-N balinganise ngokuphambene.

I-Torque=9550*amandla okukhiphayo/isivinini sokukhipha

Amandla (Watts) = Speed ​​​​(Rad/sec) x Torque (Nm)

Eqinisweni, akukho okungaxoxwa ngakho, kunefomula ethi P=Tn/9.75.Iyunithi ye-T ingu-kg·cm, kanye ne-torque=9550*amandla okukhiphayo/isivinini sokukhipha.

Amandla aqinisekile, ijubane liyashesha, futhi i-torque incane. Ngokuvamile, lapho i-torque enkulu idingeka, ngaphezu kwe-motor enamandla amakhulu, i-reducer eyengeziwe iyadingeka.Kungaqondwa ngale ndlela ukuthi lapho amandla P ehlala engashintshiwe, ijubane eliphakeme, i-torque encane yokuphumayo.

Singayibala kanje: uma wazi ukumelana ne-torque T2 yemishini, isivinini esilinganiselwe esingu-n1 se-motor, isivinini n2 se-shaft okukhiphayo, kanye nesistimu yemishini yokushayela i-f1 (le f1 ingachazwa ngokusho kwangempela. Isimo sokusebenza esizeni, eziningi zasekhaya zingaphezulu kuka-1.5 ) kanye ne-factor yamandla m yenjini (okungukuthi, isilinganiso samandla asebenzayo kumandla aphelele, okungaqondwa njengesilinganiso esigcwele se-slot kumawindi enjini, ngokuvamile ku-0.85), sibala amandla ayo e-motor P1N.P1N>=(T2*n1)*f1/(9550*(n1/n2)*m) ukuze uthole amandla enjini ofuna ukuyikhetha ngalesi sikhathi.
Isibonelo: i-torque edingwa umshini oshayelwayo ithi: 500N.M, umsebenzi amahora angu-6/ngosuku, futhi i-coefficient yemishini eshayelwayo f1=1 ingakhethwa ngomthwalo olinganayo, isinciphisi sidinga ukufakwa kwe-flange, kanye nesivinini sokuphumayo. n2=1.9r/min Bese kuba isilinganiso:
