Iwo Matsime eVibration ruzha mune zvechigarire magineti synchronous motors

Kuzunguzika kwechisingaperi magineti synchronous motorskunyanya inobva kuzvinhu zvitatu: ruzha rweaerodynamic, mechanical vibration, uye electromagnetic vibration. Ruzha rweAerodynamic runokonzerwa nekukurumidza kuchinja kwemhepo mukati memota uye kupokana pakati pegasi uye chimiro chemota. Mechanical vibration inokonzerwa ne periodic elastic deformation yemabhengi, geometric defects, uye rotor shaft kusaenzana. Electromagnetic vibration inokonzerwa ne electromagnetic excitation, uye mhepo gap remagineti rinoshanda pane stator core, zvichikonzera radial deformation ye stator, iyo inopfuudzwa kune mota casing uye inopenya ruzha. Kunyangwe iyo tangential chikamu chemhepo gap magineti idiki, inogona kukonzera cogging torque ripple uye mota vibration. Mukufambisa kwechisingaperi magineti synchronous motors, electromagnetic excitation ndiyo honzeri yekuzunguza.

Muchikamu chekutanga chekugadzira chechisingaperi magineti synchronous motors, nekumisikidza dhizaini yekupindura modhi, kuongorora zvimiro zve electromagnetic excitation uye hunhu hunochinja hwechimiro, kufanotaura uye kuongorora mwero weruzha rwekuzunguza, uye nekugadzirisa dhizaini yekuzunguza, ruzha rwekuzunguza runogona kudzikiswa, kuita kwemota kunogona kuvandudzwa, uye kutenderera kwebudiriro kunogona kupfupikiswa.

Ikozvino kufambira mberi kwekutsvaga kunogona kupfupikiswa muzvikamu zvitatu:

1.Research nezve electromagnetic excitation: Electromagnetic excitation ndicho chikonzero chikuru chekudengenyeka, uye tsvakurudzo yave ichienderera mberi kwemakore akawanda. Tsvagiridzo yepakutanga yaisanganisira kuverenga kugoverwa kwemagetsi emagetsi mukati memotor uye kuwana mafomula ekuongorora emasimba eradial. Mumakore achangopfuura, nzira dzekuyedza uye ongororo yenhamba dzakashandiswa zvakanyanya, uye nyanzvi dzepamba nedzekunze dzakadzidza pesvedzero yeakasiyana pole slot masisitimu pane cogging torque yemagineti echigarire synchronous motors.

2. Tsvakurudzo pamusoro pemaitiro ekugadzirisa maitiro: Maitiro ekugadzirisa maitiro anonyatsoenderana nemhinduro yake yekudengenyeka, kunyanya kana iyo yekusimudzira frequency iri pedyo neakasikwa frequency yechimiro, resonance ichaitika. Nyanzvi dzemudzimba nedzekunze dzakadzidza hunhu hwemotor stator masisitimu kuburikidza nekuyedza uye simulations, kusanganisira zvinhu zvinokanganisa modal frequency senge zvinhu, elastic modulus, uye zvimiro zvimiro.

3. Tsvagiridzo yeVibration Response pasi peElectromagnetic Excitation: Kudengenyeka kwemotor kunokonzerwa nekunakidzwa kwemagetsi kunobata pamazino ane stator. Vatsvagiri vakaongorora kugoverwa kwespatiotemporal kwesimba remagetsi, kurodha electromagnetic excitation pane mota stator chimiro, uye vakawana maverengero enhamba uye mhedzisiro yekuedzwa kwemhinduro yevibration. Vatsvagiri vakaongorora zvakare pesvedzero yekunyorovesa coefficient yeganda zvinhu pane vibration mhinduro.
