Iimotor ezitshintshileyo ezitshintshileyo zineempawu ezimbini ezisisiseko: 1) Ukutshintsha, ukutshintshwa kweemotor zokungafuni ukusebenza kufuneka zisebenze kwimodi yokutshintsha ngokuqhubekayo;2) Iimotor ezitshintshileyo zokuthithisa ziimotor eziguqukayo ngokuphindwe kabini.Umgaqo wayo wesakhiwo kukuba xa i-rotor ijikeleza, ukungafuni ukujikeleza kwamagnetic kufuneka kutshintshe kangangoko kunokwenzeka.Ngapha koko, umazibuthe osisigxina ofakwe kwi-rotor ye-motor yemagnethi esisigxina iya kubangela utshintsho lokungafuni kwepali ye-rotor, ngoko ke i-torque ye-magnetic motor esisigxina ikwabandakanya i-torque yokungafuni.

1. Ubume be-ontology
Izibonda ezinqabileyo ze-stator kunye ne-rotor ye-motor ye-reluctance etshintshiweyo yenziwe ngezibane eziqhelekileyo ze-silicon zentsimbi.Le nkqubo yomatshini inciphisa ilahleko yangoku kunye ne-hysteresis kwimoto.Akukho ma-windings okanye iimagnethi ezisisigxina kwiipali ze-rotor, okanye abahambi, i-slip rings, njl.Izibonda ze-stator zinxeba nge-concentrated windings, kwaye ii-windings ezimbini ezichasene ne-radially zixhunyiwe kwi-series ukuze zenze isigaba, kwaye isakhiwo esipheleleyo se-motor silula.
Iimotor ezitshintshileyo zokuthithisa zinokuyilwa zinezigaba ezahlukeneyo njengoko zifunwa.Ngokwesigaba, sahlulwe kwisigaba esisodwa, isigaba esibini, isigaba sesithathu, isigaba sesine kunye nesigaba se-multi-phase reluctance motors.Nangona kunjalo, iimotor ezitshintshileyo zokungafuni ukuya ngaphantsi kwenqanaba lesithathu ngokubanzi azinawo amandla okuziqalisa.Izigaba ezininzi injini inazo, incinci i-angle yesinyathelo, eya kunceda ukunciphisa i-torque ripple.Nangona kunjalo, ngakumbi inani lezigaba, izixhobo zokutshintsha ngakumbi zisetyenziswa, ulwakhiwo olunzima ngakumbi, kunye neendleko ezihambelanayo ziya kwanda.Iimotor zenqanaba lesithathu kunye nenqanaba lesine zisetyenziswa ngokuqhelekileyo namhlanje.Inani lezibonda ze-stator kunye ne-rotor nazo zihluke.Ngokomzekelo, i-motor ye-reluctance motor ine-6/4 isakhiwo kunye nesakhiwo se-12/8, kwaye ininzi ye-motor-switched reluctance motors ine-8/6 isakhiwo.
2. Umgaqo wokusebenza
Injini yokungafuni ukutshintshelayinjini esebenzisa ukungalingani kwe-rotor ukuvelisa i-torque, eyaziwa ngokuba yi-motor synchronous esebenzayo.Ubume bayo kunye nomgaqo wokusebenza kwahluke kakhulu kwiinjini ze-AC zemveli kunye neenjini ze-DC.Ayixhomekeke ekusebenzisaneni kwamagnetic fields ukusuka kwi-stator kunye ne-rotor winding currents ukuvelisa i-torque.
3. Iimpawu zeMoto eTshitshiweyo yokuReluctance
Kule minyaka ingama-20 idlulileyo, iinjini zokungathandi ezitshintshileyo ziye zanikwa ingqwalasela engakumbi ngabantu.Kungenxa yokuba ineempawu ezicacileyo ukuba izibonelelo zayo kunye nokungalunganga zivelele ngokulinganayo.Makhe sithethe ngeengenelo kuqala.
1. Inkqubo yokutshintsha kwemotor eguqukayo inokusebenza okuphezulu kunye nesiphumo esihle sokugcina amandla: kuluhlu olubanzi lolawulo lwesantya kunye namandla, imotor etshintshileyo yokuthandabuza isebenza kakuhle ngakumbi kunenkqubo yokulawula isantya sesantya se-asynchronous motor, kwaye ukusebenza kakuhle kunokuba phezulu. ngaphezu kwe-10 ngesantya esiphantsi okanye umthwalo olula.%Xa kuthelekiswa neenkqubo ezinje ngegiya motor deceleration, ukwehla kwepulley yesibini.
2. I-motor inokuqaliswa kwaye imiswe rhoqo, kwaye ukujikeleza phambili kunye nokubuyisela umva kuyenzeka rhoqo: ukulawula ukusebenza kwe-quadrant ezineyatshintsha injini yokungafuniiyabhetyebhetye.Xa kukho iyunithi yokuqhobosha kwaye amandla okuqhobosha ahlangabezana neemfuno, ukutshintshwa kokuqalisa ukumisa kunye nokuya phambili nokujikeleza umva kunokufikelela ngaphezu kwamakhulu amaxesha ngeyure.
3. I-motor isenokusebenza kwimeko yokulahleka kwesigaba okanye ukulayisha ngaphezulu: Xa unikezelo lwamandla luphuma kwisigaba okanye nasiphi na isigaba semoto okanye isilawuli asiphumelelanga, amandla aphumayo emotor yokutshintshiselana anokuncitshiswa, kodwa angakwazi. baleka.Xa inkqubo idlula umthwalo olinganisiweyo ngaphezu kwe-120%, isantya siya kuhla kuphela, kwaye i-motor kunye nomlawuli akayi kutshiswa.
