Basic zvemukati zvekusarudza mota

Izvo zvakakosha zvemukati zvinodiwa pakusarudzwa kwemota ndezvi: rudzi rwekuremerwa, rakayerwa simba, yakayerwa voltage, yakayerwa kumhanya, uye mamwe mamiriro.

1. Rudzi rwemutoro unotyairwa unonzi inversely kubva kuhunhu hwemota.Motors inogona kungokamurwa kuita DC mota uye AC mota, uye AC inokamurwazve kuita synchronous motors uye asynchronous motors.

Zvakanakira iyo DC mota inogona kugadzirisa zviri nyore kumhanya nekushandura voltage, uye inogona kupa yakakura torque.Inokodzera mitoro inoda kugadzirisa kukurumidza nguva zhinji, senge inokungurutsa mill mumill yesimbi, hoist mumigodhi, etc. Asi ikozvino nekuvandudzwa kweiyo frequency kutendeuka tekinoroji, iyo AC mota inogonawo kugadzirisa kukurumidza nekushandura frequency.Nekudaro, kunyangwe mutengo weiyo inosiyana frequency motors isingadhure kupfuura yakajairwa mota, mutengo wema frequency converter unotora chikamu chikuru cheseti yese yemidziyo, saka imwe mukana weDC motors ndeyekuti yakachipa.Izvo zvakashata zveDC motors ndezvekuti chimiro chakaoma.Chero bedzi chero midziyo ine chimiro chakaoma, ichaita zvisingadzivisiki kuti iwedzere kuwedzera kwekukundikana.Kuenzaniswa neAC motors, mota dzeDC hadzina kuomesesa chete mumhepo (excitation windings, commutation pole windings, compensation windings, armature windings), asiwo wedzera slip mhete, mabhurashi uye commutators.Kwete chete zvinodiwa nemaitiro emugadziri zvakakwirira, asi mari yekuchengetedza munguva inotevera zvakare yakakwira.Naizvozvo, maDC motors mumaindasitiri ekushandisa ari mumamiriro ezvinhu anonyadzisa apo ari kuderera zvishoma nezvishoma asi achine nzvimbo muchikamu chekuchinja.Kana mushandisi aine mari yakakwana, zvinokurudzirwa kusarudza chirongwa che AC mota ine frequency converter.

2. Asynchronous motor

Zvakanakira asynchronous motors iri nyore chimiro, yakagadzikana kuita, kugadzirisa kuri nyore uye mutengo wakaderera.Uye maitiro ekugadzira zvakare ari nyore.Ndakanzwa kubva kunyanzvi yekare muwekishopu kuti zvinotora maviri anoenderana mota kana mana asynchronous mota dzesimba rakafanana kuunganidza mota yeDC.Izvi zvinoonekwa.Naizvozvo, asynchronous motors ndiwo anonyanya kushandiswa muindasitiri.

2. Rated simba

Iyo yakayerwa simba remota inoreva simba rekubuda, kureva, iyo shaft simba, inozivikanwawo sechisimba, inova iconic parameter yemota.Vanhu vanowanzobvunza kuti mota yakakura sei.Kazhinji, hairevi saizi yemota, asi kune yakayerwa simba.Ndiyo inonyanya kukosha chiratidzo chekuenzanisa dhizaini yekukwevera mutoro, uye zvakare ndiyo iyo parameter inodiwa iyo inofanirwa kupihwa kana mota yasarudzwa.

Iyo musimboti wekusarudza nemazvo simba remota inofanirwa kunge iri yakanyanya hupfumi uye inonzwisisika sarudzo pasimba remota pasi pechifungidziro chekuti mota inogona kusangana nezvinodiwa zvekugadzira michina mitoro.Kana simba racho rakanyanya kukura, mari yemidziyo inowedzera, ichikonzera tsvina, uye motokari inowanzomhanya pasi pemutoro, uye kushanda nesimba uye simba re AC motokari yakaderera;pane zvinopesana, kana simba racho rakanyanya kuduku, motokari ichave yakawandisa, zvichiita kuti motokari iite nguva isati yakwana.kukuvara.Pane zvinhu zvitatu zvinotarisa simba guru remotokari: 1) kupisa uye kupisa kukwira kwemotokari, izvo zvinonyanya kukosha pakusarudza simba remotokari;2) iyo yenguva pfupi yekuremedza simba inobvumidzwa;3) iyo yekutanga simba inofanirwawo kutariswa kune iyo asynchronous squirrel cage mota.

3. Rated voltage

Iyo yakayerwa voltage yemota inoreva mutsara wemagetsi mune yakayerwa kushanda modhi.Sarudzo yeyakayerwa voltage yemota inoenderana nemagetsi emagetsi emagetsi system kune bhizinesi uye saizi yemota.

Iyo mota nemichina inoshanda inotyairwa nayo ine yavo yakayerwa kumhanya.Paunosarudza kumhanya kwemota, zvinofanirwa kucherechedzwa kuti kumhanya hakufanirwe kunge kwakaderera, nekuti yakaderera iyo yakatemerwa kumhanya kwemota, iyo yakawanda nhamba yematanho, yakakura vhoriyamu uye yakakwirira mutengo;panguva imwecheteyo, kukurumidza kwemotokari hakufaniri kusarudzwa zvakanyanya.yakakwirira, sezvo izvi zvaizoita kuti kutapurirana kuomese uye kunetsa kuchengetedza.Uye zvakare, kana simba richigara, iyo mota torque inopindirana nekumhanya.

Kazhinji kutaura, mota inogona kuverengerwa nekupa mhando yemutoro unotyairwa, iyo yakayerwa simba, yakayerwa voltage, uye yakayerwa kumhanya kwemota.Nekudaro, aya maparamendi ekutanga ari kure nekukwana kana zvinodikanwa zvemutoro zvichazadzikiswa zvakakwana.Maparamendi anodawo kupihwa anosanganisira: frequency, yekushanda system, zvakawandirwa, kirasi yekudzivirira, kirasi yekudzivirira, nguva ye inertia, mutoro wekupokana torque curve, yekuisa nzira, ambient tembiricha, urefu, zvinodiwa zvekunze, nezvimwe, izvo zvinopihwa zvinoenderana kune chaiwo mamiriro.
