Yakachinja kusada mota yekudzikisa ruzha dhizaini, dhizaini yekudzikisa dhizaini, torque ripple control dhizaini, hapana chinzvimbo sensor, uye dhizaini dhizaini yanga iri nzvimbo dzekutsvagisa dzeSRM.Pakati pavo, iyo yekudzora zano dhizaini yakavakirwa pane yemazuva ano yekudzora dzidziso ndeyekudzvinyirira ruzha, vibration uye Torque ripple sevhisi.
1. Ruzha nekuzunguzika kweSRM zvinodzvanyirira ruzha uye kuzunguzika kwe
switched relucance mota, inova ndiyo huru bhodhoro inorambidza kusimudzirwa kweSRM.Nekuda kweiyo kaviri-convex chimiro, iyo nzira yekudzora yeasymmetric hafu-bhiriji uye isiri-sinusoidal yemhepo-gap magineti, iyo SRM ine inherent ruzha, Iko vibration yakakura kupfuura iyo yeasynchronous motors uye inogara magineti mota, uye ipapo. kune akawanda-high-frequency components, ruzha rwakapinza uye runobaya, uye simba rinopinda rakasimba.Iwo mazano ekutsvagisa ekuderedza ruzha uye kuderedza vibration anowanzo kukamurwa kuita akati wandei nzira:
1) Ongororo yeModal, dzidza pesvedzero yefuremu, stator uye rotor chimiro, chivharo chekupedzisira, nezvimwe pane imwe neimwe nzira yekurongeka, ongorora mafambiro echisikigo pasi peyega yega modhi yekurongeka, Ongorora kuti iyo electromagnetic excitation frequency iri kure sei kubva kune yakasikwa frequency mota.
2) Deredza ruzha uye kudedera nekushandura chimiro che stator uye rotor, sekuchinja ji arc, chimiro, ukobvu hwejoko, kiyi chinzvimbo slotting, oblique groove, punching, nezvimwe.
3) Kune akawanda manyowani emota zvimiro akagadzirwa, asi ese ane matambudziko.Zvimwe kugadzirwa kwakaoma, mutengo wakakura, kana kurasikirwa kukuru.Pasina kusarudzika, zvese zvigadzirwa zvemurabhoritari uye zvinhu zvakaberekerwa thesis.
2. Iyo torque pulsation control yeiyo switched kusada mota
kunotanga nekudzora.Iyo yakajairika kutungamira ndeye kudzora iyo pakarepo torque kana kuvandudza avhareji torque.Kune yakavharwa-loop control uye yakavhurika-loop control.Iyo yakavharwa-loop yekudzora inoda torque mhinduro kana kuburikidza neazvino, Zvinosiyana senge voltage kuverenga torque zvisina kunanga, uye yakavhurika-loop control inonyanya kutarisa tafura.
3. Tsvagiridzo pane chinzvimbo sensor ye switched kusada mota
Iyo inotungamira isina chinzvimbo sensor mugadziri mukuru wemapepa.Muchidzidzo, kune nzira dzemajekiseni eharmonic, nzira dzekufanotaura inductance, etc. Zvinosuruvarisa, hapana ma sensors echinzvimbo mune zvigadzirwa zvemaindasitiri zvakakura kumba nekune dzimwe nyika.Sei?Ndinofunga zvichiri nekuda kwekusavimbika.Mukushandiswa kwemaindasitiri, ruzivo rwenzvimbo isingavimbike runogona kukonzera tsaona uye kurasikirwa, izvo zvisingatsungirike kumabhizinesi nevashandisi.Nzira dzezvino dzeSRM dzakavimbika dzekuona chinzvimbo dzinosanganisira dzakaderera-resolution nzvimbo sensors inomiririrwa nephotoelectric switch uye Hall switch, inosangana nezvinodiwa zvekufambiswa kwemotor nguva zhinji, uye yakakwirira-chaiyo chinzvimbo sensors inomiririrwa nephotoelectric encoder uye solvers.Sangana nekudiwa kwekutonga kwakaringana.
Izvo zviri pamusoro ndizvo zviri mukati meiyo switched kusada mota.Pakati pazvo, iyo yakakamurwa rudzi solver yakanyatsokodzera kushandiswa kweSRM, ine diki diki, yakanyanya kurongeka uye yakanaka kuchinjika kwezvakatipoteredza.Ini ndinofunga isarudzo isingadzivisike ye servo SRM mune ramangwana.
