Kutheni le nto injini ivelisa umsinga womngxuma?

Umsinga okwisekethe yesihlalo esisekelwe kwi-shaft-bearing seater yemoto ubizwa ngokuba ngumsinga we-shaft.

Izizathu zamandla ombane we-shaft:

Ukungalingani kwentsimi yamagnetic;

Kukho iiharmonics kumbane wangoku;

Ukwenziwa nokufakelwa okungekho semgangathweni, okubangela ukuba kubekho izithuba zomoya ezingalinganiyo ngenxa yokungahambelani kwe-rotor;

Kukho umsantsa phakathi kwee-semicircles ezimbini ze-stator core esuswayo;

Inani leziqwenga ze-stator core ezenziwe ngamacandelo okufaka izinto alifanelekanga.

Iingozi: Umphezulu weebheringi zemoto okanye iibhola ziya kukhukuliseka kwaye kuya kubakho ii-micropores ezifana neengongoma, nto leyo eya kwenza ukuba ukusebenza kweebheringi kube mandundu, yonyuse ilahleko yokungqubana nobushushu, kwaye ekugqibeleni ibangele ukuba ibheringi itshiswe.

Kutheni iimoto eziqhelekileyo zingasetyenziswa kwiindawo ezithe tyaba?

Ukuphakama kunemiphumo emibi ekunyukeni kobushushu bemoto, i-motor corona (i-motor ene-voltage ephezulu) kunye nokutshintsha kwe-DC motor.

Ezi zinto zintathu zilandelayo maziqatshelwe:

Okukhona ukuphakama kuphezulu, kokukhona ukunyuka kobushushu bemoto kukhulu kwaye amandla okukhupha ayancipha. Nangona kunjalo, xa ubushushu buncipha ngokunyuka kokuphakama ngokwaneleyo ukuhlawula impembelelo yokuphakama kobushushu, amandla okukhupha alinganisiweyo emoto anokuhlala engatshintshi;

Amanyathelo okuthintela iCorona kufuneka athathwe xa kusetyenziswa iimoto ezine-voltage ephezulu kwiindawo eziphakamileyo;

Ukuphakama akulunganga ekutshintsheni kwe-DC motor, ngoko ke kufuneka kuqwalaselwe ukukhethwa kwezinto zebrashi yekhabhoni.

Kutheni le nto injini ingafanele isebenze ngomthwalo olula?

Xa injini isebenza ngomthwalo omncinci, iya kubangela:

Amandla emoto aphantsi;

Ukusebenza kakuhle kwenjini kuphantsi.

Xa injini isebenza ngomthwalo omncinci, iya kubangela:

Amandla emoto aphantsi;

Ukusebenza kakuhle kwenjini kuphantsi.

Iya kubangela ukumoshwa kwezixhobo kunye nokusebenza okungekho semgangathweni.

Zithini izizathu zokugqithisa kakhulu kwenjini?

Umthwalo mkhulu kakhulu;

isigaba esingekhoyo;

Imibhobho yomoya ivaliwe;

Ixesha lokusebenza ngesantya esiphantsi lide kakhulu;

Iiharmonikhi zombane zikhulu kakhulu.

Ngowuphi umsebenzi ekufuneka wenziwe ngaphambi kokuba kusetyenziswe injini engasetyenziswanga ixesha elide?

Linganisa i-stator, ukumelana nobushushu obujikelezayo besigaba ukuya kwisigaba kunye nokuxhathisa ubushushu obujikelezayo ukuya emhlabeni.

Ukumelana nokufakwa kwe-insulation R kufuneka kuhambelane nale fomyula ilandelayo:

R＞Un/(1000+P/1000)(MΩ)

I-Un: i-voltage elinganisiweyo yokujika kwemoto (V)

P: Amandla enjini (KW)

Kwi-Un=380V motor, R＞0.38MΩ.

Ukuba ukumelana nobushushu kuphantsi, ungenza oku kulandelayo:

a: Injini isebenza ngaphandle komthwalo iiyure ezi-2 ukuya kwezi-3 ukuze yome;

b: Sebenzisa umbane otshintshanayo we-voltage ephantsi we-10% ye-voltage elinganisiweyo ukuze udlule kwi-winding okanye uqhagamshele ii-windings zesigaba esithathu ngokulandelelana uze uzibhake nge-direct current ukuze ugcine umbane kwi-50% ye-current elinganisiweyo;

c: Sebenzisa ifeni ukuthumela umoya oshushu okanye into yokufudumeza ukuze ifudumale.

Coca injini.

Tshintsha igrisi yokuthwala.

Kutheni ndingenakuqalisa injini kwindawo ebandayo ngokuthanda kwam?

Ukuba injini igcinwa kwindawo enobushushu obuphantsi ixesha elide kakhulu, iya:

Ukufakwa kwe-motor kuqhekekile;

Igrisi ethwalayo iyabanda;

Umgubo we-solder kwiindawo zokudibanisa ucingo.

Ngoko ke, injini kufuneka ifudunyezwe kwaye igcinwe kwindawo ebandayo, kwaye ii-windings kunye neebheringi kufuneka zihlolwe ngaphambi kokuba zisebenze.

Zithini izizathu zokungalingani komsinga wesigaba sesithathu kwimoto?

Ukungalingani kwamandla ombane anezigaba ezintathu;

Isebe elithile lesigaba ngaphakathi kwemoto alinawo umdibaniso ombi okanye unxibelelwano olubi;

Ukujika kwenjini ukuya ekujikeni isekethe emfutshane okanye isekethe emfutshane ukuya emhlabeni okanye isekethe ukusuka kwisigaba ukuya kwisigaba;

Impazamo yokufakelwa kweentambo.

Kutheni i-motor ye-60Hz ingenakuqhagamshelwa kumbane we-50Hz?

Xa kuyilwa i-motor, ishiti yentsimbi ye-silicon idla ngokwenziwa ukuba isebenze kwindawo yokugcwala kwe-magnetization curve. Xa i-voltage yombane ingaguquki, ukunciphisa i-frequency kuya kwandisa i-magnetic flux kunye ne-excitation current, okubangela ukwanda kwe-motor current kunye nelahleko ye-copper, ekugqibeleni ekhokelela ekwandeni kokunyuka kobushushu be-motor. Kwiimeko ezinzima, i-motor inokutsha ngenxa yokushisa kakhulu kwe-coil.
