Chimiro uye saizi yerotor slots ine yakanangana neiyo rotor kuramba uye kuvuza flux, izvo zvinozokanganisa kushanda kwemota, simba chinhu, yakanyanya torque, kutanga torque uye zvimwe zviratidzo zvekuita. Kuita kunokanganiswa kunokosha zvikurumotazvigadzirwa.
Mukushanda chaiko, zvinowanzodiwa kusiya kudiwa kwezvimwe zvivakwa zveimwe kuita. Chirevo chekare chokuti “haugoni kuwana keke rako wodyawo” chakakodzera chaizvo pano. Ehe, kumwe shanduko yetekinoroji kubudirira mune zvitsva zvinhu uye maitiro matsva achatyora mutemo uyu kwenguva. Semuenzaniso, mukutanga danho rekushandiswa kweyakakwira-voltage mota insulation system ine "mica tepi ine shoma glue poda" sechinhu chikuru chakasanganiswa nehunyanzvi hwekuita tekinoroji ye "vacuum pressure immersion coating", yakambowana mhedzisiro. ye "kuva nekeke rako uye woridya futi" maererano nekudzikisa kusimba kwekudzivirira uye kuvandudza voltage uye corona kuramba. Nekudaro, haikwanise kubvisa zvipingaidzo zvemitemo uye nguva dzose inofanirwa kutarisana nekunetsa-kubata-kubata kupokana kana kunyadziswa.
1 Performance chiyero pakati pekutanga kuita uye kuwandisa kwehuwandu
Kuti uvandudze huwandu hwemota yekuremedza, iyo yakanyanya torque inoda kuwedzerwa, saka iyo rotor leakage reactance inoda kuderedzwa; uye kuti usangane nediki yekutanga ikozvino uye yakakura yekutanga torque panguva yekutanga maitiro, iyo rotor ganda mhedzisiro inoda kuwedzerwa zvakanyanya sezvinobvira, asi iyo rotor slot leakage magineti flux uye leakage reactance inofanira kunge yakawedzera.
2 Kuenzana pakati pekubudirira uye kutanga kuita
Tinoziva kuti kuwedzera kupikisa kwe rotor kunogona kuvandudza motokari kutanga kushanda, zvakadai sekuderedza rotor slot uye kushandisa kaviri cage rotor, asi nekuda kwekuwedzera kwekudzivirira kwe rotor uye kubuda kwezvino, iyo stator uye rotor mhangura kurasikirwa kuchawedzera zvakanyanya, zvichikonzera. mukuderedza kushanda zvakanaka.
3 Cheki uye zviyero pakati pesimba chinhu uye kutanga kuita
Kuti tivandudze kuita kwekutanga kwemota, isu tinoshandisa ganda mhedzisiro, sekushandisa yakadzika nhete migero, convex grooves, banga-yakaita grooves, yakadzika grooves kana kaviri squirrel cage grooves kuwedzera rotor kuramba panguva yekutanga, asi zvakanyanya. zvakananga kukanganisa ndiko kuwedzera Rotor slot leakage yakaderedzwa, iyo rotor leakage inductance inowedzera, uye rotor reactive current inowedzera, iyo muzviitiko zvakawanda ichatungamirira zvakananga kuderedzwa kwesimba resimba.
4 Kubudirira uye simba factor performance macheki uye zviyero
Kana iyo rotor slot nzvimbo inowedzera uye kushorwa kunoderera, iyo rotor mhangura kurasikirwa kuchaderera uye kubudirira kuchawedzera kuwedzera; zvisinei, nekuda kwekudzikira kweiyo magineti permeability nzvimbo yejoko rotor, iyo magineti kuramba ichawedzera uye iyo magineti flux density ichawedzera, zvichiita kuti kurasikirwa kwesimbi kuwedzere uye simba resimba riwedzere. kuderedza. Mazhinji mamotor ane hunyanzvi sechinangwa chekugadzirisa achagara aine chiitiko ichi: kuvandudzwa kwehunyanzvi kwakakosha, asi iyo yakayerwa ikozvino yakakura uye simba chinhu chakaderera. Vatengi vanogunun'una kuti mota dzepamusoro-soro hadzina kunaka semamota akajairwa.
Pane nyaya dzakawanda dzekuwana uye kurasikirwa mukugadzira mota. Ichi chinyorwa chinongobata nemaitiro ekunze. Kuti tidzikamise hukama hwekuita uku, tinofanirwa kuongorora maitiro emukati zvakadzama uye neunyanzvi kushandisa maitiro ekudzokorora ekufunga kwekuwana nekurasikirwa kugadzirisa kunonzi kupokana kana kunyadziswa.
