【Isifinyezo】:
Ama-motor ashintshayo anokungabaza anezici ezimbili eziyisisekelo: 1) Ukushintsha, ama-motor ashintshayo adinga ukusebenza kumodi yokushintsha eqhubekayo; 2) Izinjini ezishintshayo zokungabaza zingamamotho aphindaphindayo aphindwe kabili. Umgomo wayo wesakhiwo ukuthi lapho i-rotor ijikeleza, ukungabaza kwesifunda samagnetic kufanele kushintshe ngangokunokwenzeka. Eqinisweni, umazibuthe unomphela oshumekwe ku-rotor yemoto kazibuthe ojwayelekile uzophinde ubangele ushintsho lokungabaza kwesigxobo esibalulekile se-rotor, ngakho-ke i-torque yemoto kazibuthe unomphela ihlanganisa ne-torque yokungabaza.
Ukushintsha izinjini zokuphikababe nezici ezimbili eziyisisekelo: 1) Ukushintsha, ama-motor ashintshayo adinga ukusebenza kumodi yokushintsha eqhubekayo; 2) Amamotho ashintshayo anokungabaza angamamotho aphindwe kabili ahlukile.Umgomo wayo wesakhiwo ukuthi lapho i-rotor ijikeleza, ukungabaza kwesifunda samagnetic kufanele kushintshe ngangokunokwenzeka.Eqinisweni, umazibuthe unomphela oshumekwe ku-rotor yemoto kazibuthe ojwayelekile uzophinde ubangele ushintsho lokungabaza kwesigxobo esibalulekile se-rotor, ngakho-ke i-torque yemoto kazibuthe unomphela ihlanganisa ne-torque yokungabaza.
1. Isakhiwo se-Ontology
Izigxobo ezigqamile ze-stator kanye ne-rotor ye-switched reluctance motor zenziwe ngezinsimbi ezijwayelekile ze-silicon steel laminations.Le nqubo yokwenza imishini inciphisa ukulahleka kwe-eddy current kanye ne-hysteresis motor.Awekho ama-windings noma ozibuthe abangapheli ezigxotsheni ze-rotor, noma abahambi, izindandatho zokushelela, njll.Izigxobo ze-stator zilinyazwa ngama-windings agxilile, futhi ama-windings amabili aphikisanayo axhunywe ochungechungeni ukuze enze isigaba, futhi isakhiwo sonke se-motor silula.
Amamotho ashintshayo anokungabaza angaklanywa ngezigaba ezahlukahlukene njengoba kudingeka.Ngokusho kwesigaba, ihlukaniswe ngezigaba ezilodwa, izigaba ezimbili, izigaba ezintathu, izigaba ezine kanye nezigaba eziningi zokungabaza.Kodwa-ke, amamotho ashintshayo anokungabaza angaphansi kwesigaba sesithathu ngokuvamile awanawo amandla okuziqalisa.Uma injini inezigaba eziningi, iba yincane i-engeli yesinyathelo, ezosiza ekunciphiseni i-torque ripple.Kodwa-ke, lapho inani lezigaba liba likhulu, kulapho kusetshenziswa khona amadivaysi okushintsha angaphezulu, isakhiwo siyinkimbinkimbi, futhi izindleko ezihambisanayo zizokhula.Ama-motor ezigaba ezintathu nezigaba ezine asetshenziswa kakhulu namuhla.Inombolo yezigxobo ze-stator ne-rotor nayo ihlukile. Isibonelo, i-motor eshintshashintshayo enezigaba ezintathu inesakhiwo esingu-6/4 kanye nesakhiwo se-12/8, futhi iningi lezigaba ezine ezishintshayo ezishintshashintshayo zinesakhiwo esingu-8/6.
2. Isimiso sokusebenza
Injini yokungabaza eshintshiweiyinjini esebenzisa ukungabaza okungalingani kwe-rotor ukukhiqiza i-torque, eyaziwa nangokuthi i-motor synchronous esebenzayo.Isakhiwo sayo kanye nesimiso sokusebenza kwehluke kakhulu kumamotho endabuko e-AC nama-DC motors.Ayincikile ekusebenzelaneni kwezinkundla kazibuthe kusuka kumagagasi omoya we-stator kanye ne-rotor ukuze kukhiqizwe i-torque.
3. Izici ze-Switched Reluctance Motor
Eminyakeni engu-20 edlule, izinjini ezishintshayo zokuthikaza ziye zanakwa kakhulu ngabantu.Kungenxa yokuthi inezici ezisobala ukuthi izinzuzo zayo kanye nokubi kuvelele ngokulinganayo.Ake sikhulume ngezinzuzo kuqala.
1. Isistimu ye-switched reluctance motor inokusebenza kahle okuphezulu kanye nomthelela omuhle wokonga amandla: kuhlu olubanzi lokulawula isivinini namandla, injini eshintshayo yokunqika ngokuvamile isebenza kahle kakhulu kunohlelo lokulawula isivinini esishintshashintshayo se-asynchronous motor, futhi ukusebenza kahle kungaba phezulu. kune-10 ngesivinini esiphansi noma umthwalo omncane. %; Uma kuqhathaniswa nezinhlelo ezifana ne-gear motor deceleration, ukwehla kwe-pulley yesibili.
2. Injini ingaqalwa futhi imiswe njalo, futhi ukuzungezisa ukuya phambili nokuhlehla kuvame: ukulawulwa kokusebenza kwamaquadrant amanewashintsha injini yokungafuniiyavumelana nezimo. Uma kuneyunithi yokubhuleka futhi amandla okubhuleka ahlangabezana nezidingo, ukushintsha kokuma kokuqala nokuya phambili nokuhlehlayo kungafinyelela izikhathi ezingaphezu kwamakhulu ngehora .
3. Injini isengasebenza esimweni sokulahlekelwa kwesigaba noma ukulayishwa ngokweqile: Uma ukunikezwa kwamandla kuphelile esigabeni noma noma yisiphi isigaba semoto noma isilawuli sihluleka, amandla okukhiphayo emotho eshintshayo yokungabaza angancishiswa, kodwa asengakwazi. gijima.Uma isistimu idlula umthwalo olinganiselwe ngaphezu kuka-120%, isivinini sizokwehla kuphela, futhi injini nesilawuli ngeke sishiswe.
