Sei mota ichiburitsa shaft current?

Sei mota ichiburitsa shaft current?

Mwenje uri mudunhu rechigaro chechigaro chemota unobata shaft unonzi shaft current.

Zvikonzero zve shaft current:

Kusawirirana kwesimba remagineti;

Kune ma harmonics mumagetsi emagetsi;

Kugadzirwa nekuiswa zvisina kunaka, zvichikonzera mipata isina kuenzana yemhepo nekuda kwekusagadzikana kwerotor;

Pane mukaha pakati pema semicircles maviri emudziyo we stator unobviswa;

Huwandu hwezvidimbu zvepakati pe stator zvakagadzirwa nezvikamu zve stacking hazvina kukodzera.

Njodzi: Pamusoro pemabheyaringi emota kana mabhora achabviswa uye ma micropores akafanana nepoint achaumbwa, izvo zvichaita kuti mabheyaringi awedzere kushanda, kuwedzera kurasikirwa nekukweshana uye kupisa, uye pakupedzisira kukonzera kuti bearing itsvuke.

Sei mota dzemagetsi dzisingagone kushandiswa munzvimbo dzakatetepa?

Kureba kune mhedzisiro yakaipa pakukwirira kwekupisa kwemota, corona yemota (mota ine voltage yakakwira) uye kuchinja kwemota yeDC.

Zvinhu zvitatu zvinotevera zvinofanira kucherechedzwa:

Kukwira kwenzvimbo yacho, ndiko kuwedzera kwekupisa kwemota uye simba rekubuda rinoderera. Zvisinei, kana tembiricha ikadzikira nekuwedzera kwekukwirira kwakakwana kutsiva kukanganisa kwekukwirira kwenzvimbo pakupisa, simba rekubuda rakatarwa remota rinogona kuramba risina kuchinja;

Matanho ekudzivirira corona anofanira kutorwa kana mota dzine simba guru dzichishandiswa panzvimbo dzakaoma;

Kureba hakuna kunaka pakuchinja kwemota dzeDC, saka kutarisisa kunofanira kupihwa pakusarudzwa kwezvinhu zvekushandisa bhurashi rekabhoni.

Sei mota isingafaniri kushandiswa nemutoro wakareruka?

Kana mota ichishanda nemutoro wakareruka, inokonzera:

Simba remota rakaderera;

Kushanda zvakanaka kwemota kwakaderera.

Kana mota ichishanda nemutoro wakareruka, inokonzera:

Simba remota rakaderera;

Kushanda zvakanaka kwemota kwakaderera.

Zvichakonzera kutambisa michina uye kushanda kwayo kusina mari yakawanda.

Ndezvipi zvinokonzera kupisa kwakanyanya kwemota?

Mutoro wacho wakakura zvakanyanya;

chikamu chisipo;

Mapaipi emhepo akavharwa;

Nguva yekumhanya yakaderera yakareba zvakanyanya;

Maharmoniki emagetsi akakura zvakanyanya.

Ndeipi basa rinofanira kuitwa usati waisa mota isingashandiswe kwenguva yakareba?

Yera stator, kupokana kwekudzivirira kwechikamu chimwe nechimwe uye kupokana kwekudzivirira kwechikamu chimwe nechimwe.

Kudzivirira kwekudzivirira R kunofanira kuzadzisa fomura inotevera:

R＞Un/(1000+P/1000)(MΩ)

Un: voltage yakayerwa yekumonera mota (V)

P: Simba remota (KW)

Kune mota yeUn=380V, R＞0.38MΩ.

Kana kudzivirira kwekudzivirira kupisa kwakaderera, unogona:

a: Mota yacho inomhanya isina mutoro kwemaawa maviri kusvika matatu kuti iome;

b: Shandisa low-voltage alternating current ye10% yevoltage yakayerwa kuti upfuure mu winding kana kubatanidza three-phase windings dzakatevedzana wobva wazvibika ne direct current kuti current irambe iri pa50% ye rated current;

c: Shandisa feni kutumira mhepo inopisa kana chinhu chinodziisa kuti chidziye.

Chenesa mota.

Tsiva girisi rinoisa bearing.

Sei ndisingakwanise kutanga mota munzvimbo inotonhora pandinoda?

Kana mota ikachengetwa munzvimbo ine tembiricha yakaderera kwenguva yakareba, ichaita zvinotevera:

Kudzivirira kwemota kwakatsemuka;

Girisi rinoita kuti mafuta agare kwenguva refu;

Upfu hwesolder panosangana waya.

Saka, mota inofanira kudziyiswa uye kuchengetwa munzvimbo inotonhora, uye mawindings nemabearing zvinofanira kuongororwa zvisati zvaitwa.

Ndezvipi zvikonzero zvekusagadzikana kwemagetsi matatu-phase mumota?

Kusawirirana kwemagetsi echikamu chetatu;

Bazi rechikamu chimwe chete riri mukati memota harina welding yakanaka kana kuti harina kubatana zvakanaka;

Kutenderedza mota kunotenderera-ku-ku-kutendeuka dunhu pfupi kana dunhu pfupi kuenda pasi kana kuti phase-to-phase;

Kukanganisa kwekubatanidza waya.

Sei mota ye60Hz isingabatanidzwe kune simba re50Hz?

Pakugadzira mota, simbi yesilicon inowanzo shandiswa munzvimbo ine magnetization curve. Kana voltage yemagetsi isingachinji, kuderedza frequency kunowedzera magnetic flux uye excitation current, zvichikonzera kuwedzera kwemota uye kurasikirwa nemhangura, izvo zvinozopedzisira zvaita kuti tembiricha yemota ikwire. Muzviitiko zvakakomba, mota inogona kupiswa nekuda kwekupisa kwakanyanya kwecoil.

Ndezvipi zvikonzero zvekurasikirwa kwechikamu chemotokari?
Magetsi:

Kubata switch zvisina kunaka;

Transformer kana kutyoka kwemutsetse;

Fuse yaputika.

Chimiro chemota:

Zvikuruu zviri mubhokisi remota hazvina kusimba uye kubatana kwacho hakuna kunaka;

Kuisa waya dzemukati zvisina kunaka;

Kutenderedza mota kwakaputsika.

Ndezvipi zvinokonzera kudedera kusingawanzoitiki uye ruzha rwemota?
Zvinhu zvemakanika:
Kunyorovesa mabheyaringi uye kusakara kwemabheyaringi;
Zvikuruu zvekusunga zvakasununguka;
Mune marara mukati memota.
Zvinhu zvemagetsi:
Kushanda kwemotokari zvakanyanya;
Kusawirirana kwemagetsi echikamu chetatu;
chikamu chisipo;
Kukanganisa kwedunhu pfupi kunoitika mu stator ne rotor windings;
Chikamu chekunamira che rotor ye cage chakavhurika uye chinokonzera matanda akatyoka.
Ndeipi basa rinofanira kuitwa usati watanga injini?

Yera simba rekudzivirira kupisa (kune mota dzine voltage shoma, haifanirwe kunge iri pasi pe0.5MΩ);

Yera voltage yemagetsi. Tarisa kana waya yemota yacho yakarurama uye kana voltage yemagetsi ichizadzisa zvinodiwa;

Tarisa kana michina yekutanga iri mumamiriro akanaka;

Tarisa kana fuse yakakodzera;

Tarisa kana mota iri pasi uye kana pasina kubatana kwakanaka;

Tarisa kana paine zvikanganiso pakutumira mameseji;

Tarisa kana nzvimbo yemotokari yakakodzera uye bvisa zvinhu zvinobvira moto nemamwe marara.

Ndezvipi zvikonzero zvekunyanya kupisa kwemotokari?

Mota yacho pachayo:

Mhete dzemukati nedzekunze dzebheyaringi dzakanyanya kuoma;

Kune matambudziko ekusakwanisa kwezvikamu kuita chimiro nenzvimbo, zvakaita sekusagadzikana kwezvikamu zvakaita sebase remuchina, chifukidziro chekupedzisira, uye mubato;

Kusarudzwa kusina kunaka kwemabheyaringi;

Bearing haina mafuta akawandisa kana bearing haina kucheneswa zvakanaka, uye pane marara mumafuta;

akisi yemagetsi.

Mashandisirwo:

Kuiswa kweyuniti zvisina kunaka, zvakaita sekuwirirana kwemubato wemota nemudziyo unofambiswa hazvienderane nezvinodiwa;

Pulley yakadhonzwa zvakasimba;

Mabheringi haana kuchengetwa zvakanaka, mafuta haana kukwana kana kuti nguva yebasa yapera, uye mabheringi anooma uye anoora.

Ndezvipi zvikonzero zvekusadzivirira kudziya kwemotokari?

Kutenderedza kwacho kwakanyorova kana kuti kune kupindira kwemvura;

Guruva kana mafuta zvinoungana pamakonzo;

Kukwegura kwekudzivirira;

Kudzivirira kwemota kana waya yebhodhi kwakuvadzwa.
