Kushintshiwe Ukunqikaza Motor Magnets

I-switched reluctance motor iwuhlobo olukhethekile lwenjini ene-rotor equkethe amapheya amaningi wezigxobo, i-pole pair ngayinye ehlanganisa uzibuthe kanye nokuba madolonzima. Izinjini ezishintshayo zokungabaza zivame ukusetshenziswa ezinhlelweni ezidinga i-torque ephezulu kanye nokusebenza kahle okuphezulu, njengezimoto zikagesi namadrayivu emboni.

Emotweni eshintshayo yokungabaza, odonsa ngokuvamile bangozibuthe baphakade futhi basetshenziselwa ukwakha inkambu kazibuthe ehlala njalo. Ama-Magneto-resistors enziwe ngezinto kazibuthe ezilawulwa amandla kagesi ukuze kulungiswe amandla nesiqondiso sensimu kazibuthe. Lapho i-current idlula ngokunqikaza, i-magnetism yokungabaza iyanda, idala insimu enamandla yamagnetic eheha umazibuthe ekungabazeni okuseduze nayo. Le nqubo ibangela ukuthi i-rotor ijikeleze, eshayela injini.

Umazibuthe udlala indima ekukhiqizeni inkambu kazibuthe ehlala unomphela kumotho eshintshashintshayo yokunqikaza, futhi ukungabaza kulungisa amandla nesiqondiso senkundla kazibuthe ukuze ulawule ukusebenza kwemoto.

Isimiso esiyisisekelo sokusebenza se-switched reluctance motor

I-switched reluctance motor (Switched Reluctance Motor, SRM) yemoto kagesi inesakhiwo esilula. I-stator ithatha isakhiwo esigxilile somoya, kuyilapho i-rotor ingenayo i-winging. Isakhiwo senjini eshintshayo yokungabaza kanye ne-induction stepping motor kuyafana ngandlela thize, futhi zombili zisebenzisa amandla kazibuthe (i-Max-well force) phakathi kwemidiya ehlukene ngaphansi kwesenzo senkundla kazibuthe ukukhiqiza itorque kagesi.

I-stator kanye ne-rotor ye-switched reluctance motor yenziwe nge-silicon steel sheet laminations futhi yamukela isakhiwo esibucayi. Izigxobo ze-stator kanye ne-rotor ye-switched reluctance motor zihlukile, futhi kokubili i-stator ne-rotor ine-cogging encane. I-rotor yakhiwe ngomgogodla wensimbi ozibuthe ophezulu ngaphandle kwamakhoyili. Ngokuvamile, i-rotor inezigxobo ezimbili ezingaphansi kwe-stator. Kunezinhlanganisela eziningi zama-stators nama-rotor, ezivamile yisakhiwo se-stators eziyisithupha kanye nama-rotor amane (6/4) kanye nesakhiwo se-stator eyisishiyagalombili nama-rotor ayisithupha (8/6).

Switched reluctance motor is a type of speed control motor developed after DC motor and brushless DC motor (BLDC). The power levels of the products range from a few watts to hundreds of kw, and are widely used in the fields of household appliances, aviation, aerospace, electronics, machinery and electric vehicles.

Ilandela isimiso sokuthi i-flux kazibuthe ihlale ivaliwe endleleni ngokufinyelela okukhulu kazibuthe, futhi ikhiqize amandla adonsayo kazibuthe ukuze kwakheke itorque kazibuthe yetorque. Ngakho-ke, isimiso sayo sesakhiwo siwukuthi ukungabaza kwesifunda kazibuthe kufanele kushintshe ngangokunokwenzeka lapho i-rotor ijikeleza, ngakho-ke i-motor yokungabaza eshintshiwe ithatha isakhiwo se-pole salient kabili, futhi inani lezigxobo ze-stator ne-rotor lihlukile.

Isifunda esishintshayo esilawulekayo isiguquli, esakha isekethe yamandla eyinhloko kanye nokunikezwa kwamandla kanye nokujika kwemoto. I-position detector iyisici esibalulekile se-switched reluctance motor. Ithola indawo ye-rotor ngesikhathi sangempela futhi ilawula umsebenzi wesiguquli ngokuhlelekile nangempumelelo.

I-motor ine-torque enkulu yokuqalisa, yamanje encane eqalayo, ukuminyana kwamandla aphezulu kanye ne-torque inertia ratio, impendulo eguquguqukayo, ukusebenza kahle okuphezulu ebangeni elibanzi lejubane, futhi ingabona kalula ukulawulwa kwama-quadrant amane. Lezi zici zenza injini eshintshayo yokungabaza ifaneleke kakhulu ukusebenza ngaphansi kwezimo ezihlukahlukene zokusebenza zezimoto zikagesi, futhi iyimodeli enamandla amakhulu phakathi kwezinjini zezimoto zikagesi. I-switched reluctance motor drive isebenzisa izinto zikazibuthe ezisebenza unomphela kumzimba wemoto oshintshwayo, okuwukuthuthukiswa okunamandla esakhiweni semoto. Injini ngaleyo ndlela inqoba ukushiyeka kokuhamba kancane kanye nokusetshenziswa kwamandla aphansi kuma-SRM endabuko, futhi inyusa ukuminyana kwamandla athile enjini. I-motor ine-torque enkulu, enenzuzo kakhulu ekusebenziseni kwayo ezimotweni zikagesi.
