Manyuko eruzha rwekuzununguka mumamota emagetsi asingaperi anoenderana nemagnet

Kudengenyeka kwemota dzinoenderana nemagineti dzisingaperiZvikurukuru zvinobva pazvinhu zvitatu: ruzha rwemhepo, kudedera kwemechanical, uye kudedera kwemagetsi. Ruzha rwemhepo runokonzerwa nekuchinja nekukurumidza kwekumanikidzwa kwemhepo mukati memota uye kukweshana pakati pegasi nechimiro chemota. Kudedera kwemechanical kunokonzerwa nekuchinja kwe elastic kwemabearings nguva nenguva, zvikanganiso zve geometric, uye kusawirirana kwe rotor shaft. Kudedera kwemagetsi kunokonzerwa ne electromagnetic excitation, uye air gap magnetic field inoshanda pa stator core, zvichikonzera radial deformation ye stator, iyo inotumirwa ku motor casing uye inoburitsa ruzha. Kunyangwe chikamu che tangential che air gap magnetic field chiri chidiki, chinogona kukonzera cogging torque ripple uye motor vibration. Mukufambisa kwemota dzinoenderana nemagineti dzisingaperi, kukwidziridzwa kwemagetsi ndiko kunonyanya kukonzera kudedera.

Padanho rekutanga rekugadziramota dzinoenderana nemagineti dzisingaperi, nekugadzira modhi yekupindura kubvunda, kuongorora hunhu hwekufadza kwemagetsi uye hunhu hwesimba rechimiro, kufanotaura nekuongorora huwandu hweruzha rwekubvunda, uye kugadzirisa dhizaini yekubvunda, ruzha rwekubvunda runogona kuderedzwa, mashandiro emota anogona kuvandudzwa, uye kutenderera kwekukura kunogona kupfupikiswa.

Kufambira mberi kwekutsvaga kuri kuitwa pari zvino kunogona kupfupikiswa muzvikamu zvitatu:

1. Tsvagiridzo pamusoro pekukwezvwa kwemagetsi: Kukwezvwa kwemagetsi ndicho chikonzero chikuru chekukwezvwa, uye tsvagiridzo yave ichienderera mberi kwemakore mazhinji. Tsvagiridzo yekutanga yaisanganisira kuverenga kugoverwa kwemasimba emagetsi mukati memamota uye kuwana mafomula ekuongorora emasimba emagetsi. Mumakore achangopfuura, nzira dzekuenzanisa zvinhu zvakati wandei uye ongororo yenhamba dzakashandiswa zvakanyanya, uye nyanzvi dzemuno nedzekunze dzakadzidza nezve pesvedzero dzakasiyana dzemapombi emagetsi pa torque yemagetsi emagetsi anogara kwenguva refu.

2. Tsvagiridzo pamusoro pehunhu hwechimiro: Hunhu hwechimiro hunoenderana zvakanyanya nemhinduro yaro yekudedera, kunyanya kana frequency yekufemera iri pedyo nefrequency yechisikigo, kurira kunoitika. Nyanzvi dzemuno nedzekunze dzakadzidza hunhu hwechimiro chemotor stator systems kuburikidza nekuyedza uye simulations, kusanganisira zvinhu zvinokanganisa mafrequency emodal akadai sezvinhu, elastic modulus, uye structural parameters.

3. Tsvagiridzo pamusoro peKupindura kweKudengenyeka pasi peKukurudza kweMagineti: Kupinduka kwemota kunokonzerwa nekukurudza kwemagetsi kunoshanda pamazino e stator. Vaongorori vakaongorora kugoverwa kwesimba remagetsi panzvimbo, vakaisa electromagnetic excitation pachimiro che stator yemota, uye vakawana maverengero enhamba uye mhedzisiro yekuyedza yemhinduro yekudengenyeka. Vaongorori vakaongororawo pesvedzero ye damping coefficient yezvinhu zvegoko pamhinduro yekudengenyeka.
