Xa kuthelekiswa neenjini ze-asynchronous, iimotor zemagnethi ezisisigxina zineengenelo ezininzi ezicacileyo.Iimotor ze-synchronous zemagnethi ezisisigxina zineempawu ezininzi ezinje ngokuba namandla aphezulu, isalathisi sokukwazi ukuqhuba kakuhle, ubungakanani obuncinci, ubunzima obulula, ukunyuka kobushushu obuphantsi, njl.njl. Kwangaxeshanye, zinokuphucula ngcono umgangatho wegridi yamandla, zinike ukudlala ngokupheleleyo. kumthamo wegridi yamandla ekhoyo, kwaye ugcine utyalo-mali lwegridi yamandla.
Ukusebenza kunye nothelekiso lwamandla
I-asynchronous motor emsebenzini, i-rotor ejikelezayo ukufunxa inxalenye yamandla kwi-excitation yegridi, ukwenzela ukuba ukusetyenziswa kwamandla egridi, le nxalenye yamandla ukuya kwinqanaba lokugqibela kwi-rotor ejikelezayo kubushushu obusetyenzisiweyo, i-akhawunti yelahleko malunga ne-20-30% yelahleko iyonke yemoto, ekhokelela ngokuthe ngqo ekunciphiseni ukusebenza kakuhle kwemoto.I-Rotor excitation yangoku iguqulelwe kwi-stator winding yi-inductive current, ukwenzela ukuba i-current in the stator winding i-lags emva kombane wegridi, okukhokelela ekunciphiseni kwamandla ombane we-motor.
Ukongeza, i-asynchronous motor kwindawo yomthwalo (= P2 / Pn) <50%, ukusebenza kwayo ngokufanelekileyo kunye nokusebenza kwamandla okusebenza kuyancipha kakhulu, ngoko ngokubanzi kufuna ukuba isebenze kummandla wezoqoqosho, oko kukuthi, izinga lomthwalo we-75% - 100%.
Imagnethi esisigxina ye-synchronous motor kwi-rotor efakwe kwimagnethi esisigxina, umazibuthe osisigxina ukuseka i-rotor magnetic field, ekusebenzeni okuqhelekileyo, i-rotor kunye ne-stator magnetic field synchronous operation, akukho okwangoku kwi-rotor, akukho lahleko yokumelana ne-rotor, kuphela lo unokuphucula ukusebenza kakuhle kwemoto nge-4% ukuya kuma-50%.Kwangaxeshanye, ngenxa yokuba akukho vuselelo lwangoku kwi-rotor yemagnethi esisigxina ye-synchronous motor, i-stator winding inokuba ngumthwalo ochasayo, ukuze amandla ombane aphantse abe yi-1. > i-20%, ukusebenza kwayo kakuhle kunye nokusebenza kwamandla okuguquguqukayo okuncinci, kunye nokusebenza kakuhle yi-80%.
Ukuqalisa itorque
Ukuqala kwe-asynchronous motor, i-motor iyadingeka ukuba ibe ne-torque enkulu ngokwaneleyo, kodwa ngethemba lokuba i-torque yokuqala ayinkulu kakhulu, ukuze ingavelisi ukuhla kwamandla ombane aphezulu kwigridi kwaye ichaphazele ukusebenza okuqhelekileyo kwezinye iinjini kunye nezixhobo zombane eziqhagamshelweyo. kwigridi.Ukongeza, xa isiqalo sangoku sisikhulu kakhulu, i-motor ngokwayo iya kuba phantsi kwempembelelo yamandla ombane, ukuba kaninzi iqala, kukho ingozi yokushisa i-windings.Ke ngoko, uyilo lokuqalisa lwe-asynchronous motor luhlala lujongene nengxaki.
Imagnethi esisigxina ye-synchronous motor inokuphinda isetyenziswe kwimowudi yokuqala ye-asynchronous, ngenxa yemagnethi esisigxina ye-synchronous motor yesiqhelo yokusebenza kwe-rotor winding ayisebenzi, kuyilo lwenjini yemagnethi esisigxina, ukujika kwe-rotor kunokwenziwa ukuhlangabezana ngokupheleleyo neemfuno ze-rotor. I-torque ephezulu yokuqalisa, umzekelo, ukuze i-torque yokuqala iphindaphinde nge-asynchronous motor 1.8 amaxesha ukuya ku-2.5 amaxesha, okanye nangaphezulu, isisombululo esingcono kwisixhobo samandla esiqhelekileyo, Isombulula ngempumelelo into "yamahashe amakhulu atsala imoto encinci.t” kwizixhobo zombane eziqhelekileyo.
Ukusebenzaukunyuka kobushushu
Njengomsebenzi we-asynchronous motor, i-rotor winding flow flow yangoku, kwaye le yangoku ikwimo yokusetyenziswa kwamandla ashushu, ngoko kwi-rotor winding iya kuvelisa ubushushu obukhulu, ukwenzela ukuba ubushushu bemoto buphakame, obuchaphazela kakhulu. ubomi benkonzo yemoto.
Ngokubhekiselele kwimotor esisigxina yemagnethi ehambelanayo, ngenxa yokusebenza okuphezulu kwenjini yemagnethi esisigxina, akukho lahleko yokuxhathisa kwi-rotor winding, kuncinci okanye akukho phantse akukho nto isebenzayo kwi-stator winding, ukuze ukunyuka kobushushu bemoto kusezantsi. , eyandisa ngcono ubomi benkonzo yemoto.
Impembelelo ekusebenzeni kwegridi
Ngenxa yamandla asezantsi enjini ye-asynchronous motor, i-motor idinga ukufunxa isixa esikhulu sangoku esisebenzayo kwigridi yamandla, ngaloo ndlela ibangela inani elikhulu langoku elisebenzayo kwigridi yamandla, izixhobo zokuhambisa kunye nenguqu kunye nezixhobo zokuvelisa amandla, ngaloo ndlela umgangatho womgangatho wokuhla kwegridi yamandla, enganelisi nje umthwalo wegridi yamandla kunye nokuhanjiswa kunye nezixhobo zokuguqula kunye nezixhobo zokuvelisa amandla, kwangaxeshanye, umbane osebenzayo udla inxalenye yamandla ombane kwigridi yamandla, ukuhanjiswa kunye izixhobo zenguqu kunye nezixhobo zokuvelisa amandla, okukhokelela ekusebenzeni okuphantsi kunye nokuchaphazela igridi yamandla ombane.Ngelo xesha, umbane osebenzayo usebenzisa inxalenye yamandla ombane kwigridi yamandla, izixhobo zokuhambisa kunye nenguqu kunye nezixhobo zokuvelisa amandla, okubangela ukuba igridi yamandla ingasebenzi kakuhle kwaye ichaphazela ukusetyenziswa kwamandla ombane ngokufanelekileyo.Ngokufanayo, ngenxa yokusebenza okuphantsi kweenjini ze-asynchronous, ukuhlangabezana nemfuno yamandla aphumayo, kuyimfuneko ukufunxa amandla amaninzi kwigridi, ngaloo ndlela ukwandisa ukulahlekelwa kwamandla ombane kunye nokunyusa umthwalo kwigridi.
Kwaye kwi-injini ye-synchronous yemagnethi esisigxina, i-rotor yayo ngaphandle kwe-excitation yangoku, i-motor power factor nayo iphezulu, engaphuculi kuphela umgangatho wegridi, ukuze igridi ingasafuni ukufaka izixhobo zembuyekezo yamandla asebenzayo.Ngaphezu koko, ngenxa yokusebenza okuphezulu kwe-magnetic synchronous motor esisigxina, ikwagcina amandla egridi
I-Anhui Mingteng eSisigxina-oomatshini bakaMagnetic & neZixhobo zoMbane Co., Ltd.yasekwa ngo-2007 kwaye ngomnye wabavelisi bokuqala e-China ukuphuhlisa nokuvelisa iinjini zemagnethi ezisisigxina.Ine-R&D ebanzi, imveliso, intengiso, kunye neqela emva kokuthengisa.Inkampani isoloko ibambelele kuphuhliso oluzimeleyo kwaye ithobela umgaqo-nkqubo weshishini "weemveliso zodidi lokuqala, ulawulo lodidi lokuqala, iinkonzo zodidi lokuqala, kunye neempawu zodidi lokuqala", ukuthunga izisombululo ezinengqondo zemagnethi ezisisigxina zokonga umbane jikelele kubasebenzisi. , kunye nokuzabalazela ukuba yinkokeli kunye nomseki osemgangathweni kushishino lweemoto ezizibuthe zaseTshayina ezinqabileyo zomhlaba.
