Chimiro nehukuru hwenzvimbo dzerotor zvine chekuita zvakananga nekuramba kwerotor uye kubuda kwemvura, izvo zvinozokanganisa kushanda zvakanaka kwemota, simba, torque yepamusoro, torque yekutanga nezvimwe zviratidzo zvekushanda. Kushanda kwakakanganiswa kwakakosha zvikuru kumotazvigadzirwa.
Mukushanda chaiko, zvinowanzodiwa kurega kuda zvimwe zvinhu kuti zviite basa rakati. Chirevo chekare chekuti "haugone kuva nekeke rako woridyawo" chakakodzera pano. Ehe, kumwe kufambira mberi kwetekinoroji mune zvinhu zvitsva uye maitiro matsva kuchatyora mutemo uyu kwenguva pfupi. Semuenzaniso, pakutanga kwekushandiswa kwesystem yekudzivirira mota ine voltage yakawanda ne "mica tape ine glue powder shoma" sechinhu chikuru chakabatanidzwa netekinoroji itsva ye "vacuum pressure immersion coating", yakambowana mhedzisiro yekuti "kuva nekeke rako woridyawo" maererano nekuderedza ukobvu hwekudzivirira uye kuvandudza voltage uye corona resistance. Zvisinei, haigone kubvisa zvirambidzo zvemitemo uye inogara ichitarisana nekusawirirana kwakaoma kubata kana kunyara.
1 Kuenzana kwekushanda pakati pekutanga kushanda uye huwandu hwezvinhu zvinorema
Kuti injini iwedzere simba rayo, torque yepamusoro inofanira kuwedzerwa, saka rotator leakage reactance inofanira kuderedzwa; uye kuti isangane ne starting current diki uye starting torque hombe panguva yekutanga, rotor skin effect inofanira kuwedzerwa zvakanyanya sezvinobvira, asi rotor slot leakage magnetic flux uye leakage reaction inofanira kuwedzerwa zvisingadzivisike.
2 Kuenzana pakati pekushanda zvakanaka uye kutanga kushanda zvakanaka
Tinoziva kuti kuwedzera kusimba kwerotor kunogona kuvandudza mashandiro ekutanga kwemota, zvakaita sekuderedza nzvimbo yerotor uye kushandisa rotor ine cage mbiri, asi nekuda kwekuwedzera kwekudzivirira kwerotor uye kubuda kwemvura, kurasikirwa kwemhangura ye stator neyerotor kuchawedzera zvakanyanya, zvichikonzera kudzikira kwekushanda.
3 Kutarisa uye kuyera pakati pesimba remagetsi nekushanda kwekutanga
Kuti tivandudze mashandiro ekutanga kwemota, tinoshandisa ganda, senge kushandisa migero yakadzika yakamanikana, migero yakakomberedzwa, migero yakaita sebanga, migero yakadzika kana migero miviri ye squirrel cage kuwedzera kusimba kwe rotor panguva yekutanga, asi chinonyanya kukanganiswa ndechekuwedzera. Kudonha kwe rotor slot kunoderedzwa, inductance yekudonha kwe rotor inowedzerwa, uye simba re rotor rinoita reactive rinowedzerwa, izvo kazhinji zvinotungamira zvakananga kukudzikira kwesimba remagetsi.
4 Kuongororwa uye kuenzana kwekushanda zvakanaka uye simba rezvinhu
Kana nzvimbo yerotor slot ikawedzera uye resistance ikadzikira, kurasikirwa kwemhangura yerotor kuchaderera uye kushanda zvakanaka kuchawedzera; zvisinei, nekuda kwekuderera kwenzvimbo yemagnetic permeability yerotor joke, resistance yemagnetic ichawedzera uye magnetic flux density ichawedzera, zvichikonzera kurasikirwa kwesimbi kuwedzera uye simba riwedzere kudzikira. Mota zhinji dzine efficiency sechinangwa che optimization dzichagara dziine chiitiko ichi: kuvandudzwa kwekushanda zvakanaka kwakakosha, asi rated current yakakura uye simba rakaderera. Vatengi vanonyunyuta kuti mota dzinoshanda zvakanyanya hadzina kunaka semota dzakajairika.
Kune nyaya dzakawanda dzekubudirira nekurasikirwa mukugadzirwa kwemotokari. Chinyorwa chino chinongobata nehunhu hwekunze chete. Kuti tienzanise hukama uhwu hwekushanda, tinofanira kuongorora hunhu hwemukati zvakadzama uye kushandisa neunyanzvi mafungiro ekudzokorora ekubudirira nekurasikirwa kugadzirisa zvinonzi kusawirirana kana kunyara.
