Mota overload (Motor overload) inzvimbo iyo simba rekushandisa remota rinopfuura simba rakayerwa. Kana iyo motokari inoremerwa, mashandiro acho ndeaya: mota inopisa zvakanyanya, kumhanya kunodonha, uye inogona kutomira; injini ine muffled ruzha runoperekedzwa neimwe vibration; kana mutoro ukachinja zvakanyanya, kumhanya kwemota kunochinja.
Zvikonzero zvekuremerwa kwemota zvinosanganisira kushaikwa kwechikamu chekushanda, kushanda kwemagetsi kunodarika kukosha kunotenderwa kweiyo yakayerwa voltage, uye kumhanya kwemota kunodonha kana kumira nekuda kwekutadza kwemuchina.
Kuwanda kwekushanda kwemota kuchakanganisa zvakanyanya hupenyu hwebasa remota. Kuratidzwa kwakananga kwekuremerwa ndeyekuti yazvino yemotor inova yakakura, izvo zvinotungamira mukupisa kwakanyanya kwemotor winding, uye mhepo yekuvharisa iri kuchembera uye haishande nekuda kwekunyanya kupisa.
Mushure mekunge mota yaremerwa, inogona kutongwa kubva kumamiriro chaiwo emhepo. Iyo chaiyo kuita ndeyekuti iyo yekuvharisa chikamu chemhepo inotenderedza yakasviba yese, uye mhando yacho ndeye brittle uye crisp. Muzviitiko zvakakomba, chikamu chekudzivirira chiri chose chine carbonized muupfu; Nekuchembera, firimu yepende ye enameled wire inova yakasviba, uye mumatambudziko akaoma, iri mumamiriro ekudururwa kwakakwana; nepo kune mica waya uye waya-yakaputirwa insulated electromagnetic waya, iyo insulation layer inoparadzaniswa kubva kune conductor.
iye hunhu hwekuremerwa mota windings izvo zvakasiyana nekurasikirwa kwechikamu, kutendeuka-kutendeuka, pasi-pasi-pasi uye chikamu-kune-chikamu kukanganisa ndiko kuchembera kwemhepo seyakazara, pane matambudziko emunharaunda.Nekuda kwekuremerwa kwemota, dambudziko rekupisa rekutakura system richabva zvakare.Motokari ine mhosva yakawandisa inoburitsa kunhuhwirira kwakanyanya munzvimbo yakatenderedza, uye kana yanyanya, inoperekedzwa nehutsi dema dema.
Kunyangwe iri bvunzo yekuongorora kana bvunzo yefekitori, kumwe kutadza panguva yekuyedza kuchaita kuti mota iwedzere uye kukundikana.
Munguva yekuongorora uye bvunzo, zvinongedzo zvinotarisana nedambudziko iri ndiyo bvunzo yemota uye wiring nekumanikidza application link.Stalled rotor test ndiyo yatinodaidza kuti short-circuit test, kureva kuti, rotor iri muchimiro chakamira panguva yekuyedzwa. Kana iyo nguva yekuyedza yakarebesa, iyo mota windings ichapiswa nekuda kwekupisa; yenyaya yekusakwana kugona kwemidziyo yekuyedza, kana mota ikatanga kwenguva yakareba, Kureva kuti, mune yakaderera-inomhanya inokambaira mamiriro atinowanzo kusangana nawo, iyo mota windings ichapisa zvakare nekuda kwekupisa.Dambudziko rinowanzo kuitika mumotor wiring link nderekubatanidza mota iyo inofanirwa kunge yakabatana-nyeredzi zvinoenderana neiyo delta yekubatanidza nzira, uye kudzvanya iyo yakatemerwa voltage inoenderana neiyo nyeredzi yekubatanidza, uye mhepo inoputika ichapisa munguva pfupi. nekuda kwekupisa; kune zvakare yakajairika Dambudziko nderekuedzwa kwemamotor ane ma frequency akasiyana uye akasiyana voltages. Vamwe vagadziri vemota kana vagadziri vekugadzirisa vanongove nemagetsi frequency magetsi ekushandisa kwavo bvunzo. Paunenge uchiyedza mamotor ane frequency yakakwira kupfuura simba frequency simba, iwo ma windings anowanzo kutsva nekuda kwekuwandisa voltage.
Muyedzo yemhando, iyo yakakiyiwa-rotor bvunzo chinongedzo chinowanzo kuwedzeredza kukanganisa. Kana ichienzaniswa neyefekitari bvunzo, nguva yekuyedza uye yekuunganidza mapoinzi zvakare akawanda, uye kuita kwemota pachayo hakuna kunaka kana kukanganisa kushanda kwebvunzo kunowanzoitika. Dambudziko rekuwedzera; Uye zvakare, kune iyo yekuyera bvunzo maitiro, kana mutoro usingaite, kana kuita kwekuremerwa kwemota kusina kukwana, dambudziko remhando yepamusoro yemota richaonekwa zvakare.
Nechepfungwa, kana mutoro ukaiswa zvinoenderana neyakayerwa simba remota, kushanda kwemota kwakachengeteka, asi kana voltage yemagetsi yakawandisa kana kuderera, zvinokonzeresa kuti mhepo inopisa uye kupisa. ; kuwedzera kamwe kamwe kwemutoro wemota kuchaita kuti kumhanya kwemota kungoerekana kuderera kana kutombomira idambudziko rakajairika rekuremerwa panguva yekushanda, kunyanya kune zvinokanganisa mitoro, uye dambudziko iri rakanyanya.
