Chii chinofanira kuramba cheiyo stator mhepo yechitatu-chikamu asynchronous mota inoonekwa seyakajairika zvichienderana nekugona?(Nezvekushandisa bhiriji uye kuverenga kupikisa kunoenderana nedhayamita yewaya, hazvigoneke.) Kune mota dziri pasi pe10KW, iyo multimeter inoyera mashoma ohms.Kune 55KW, iyo multimeter inoratidza zvishoma zvegumi.Rega kuita inductive reactance izvozvi.Kune 3kw nyeredzi-yakabatana mota, iyo multimeter inoyera mhepo inopokana yechikamu chimwe nechimwe kuti iite 5 ohms (maererano nemota nameplate, ikozvino: 5.5A. Power factor = 0.8. Inogona kuverengerwa kuti Z=40 ohms, R = 32 ohms).Musiyano pakati pezviviri zvakare wakakurisa.

Kubva pakutanga mota kusvika padanho rekutanga rekushanda kwakazara, mota inomhanya kwenguva pfupi uye tembiricha haina kukwirira.Mushure mekumhanya kweawa 1, tembiricha inosimuka kusvika kune imwe nhanho, simba remota rinodonha zvakanyanya mushure meawa imwe chete?Sezviri pachena kwete!Pano, ndinovimba shamwari dzine ruzivo dzemagetsi dzinogona kusuma kuti unoyera sei.Shamwari dzinovhiringikawo pakugadzirisa mota dzinogona kugovera kuti unoinzwisisa sei?

Wedzera mufananidzo kuti uone:

Kupokana kwematatu-chikamu mhepo yemota inoyerwa sezvinotevera:

1. Sunungura chidimbu chekubatanidza pakati pemagetsi emagetsi.

2. Shandisa iyo yakaderera-inopikisa huwandu hwedhijitari multimeter kuyera kushorwa pakutanga uye pakupera kwematatu emagetsi emota.Mumamiriro ezvinhu akajairika, kushorwa kweatatu windings kunofanira kuenzana.Kana pane kukanganisa, kukanganisa hakugoni kuva kukuru kudarika 5%.

3. Kana iyo injini inoputika inopikisa yakakura kudarika 1 ohm, inogona kuyerwa nebhiriji-ruoko rumwe chete.Kana iyo mota inomonereka kuramba isingasviki 1 ohm, inogona kuyerwa nebhiriji remaoko maviri.

Kana pane mutsauko mukuru mukupikisa pakati pemagetsi emagetsi, zvinoreva kuti mavhiriji emotokari ane mafupi mafupi, masheketi akazaruka, urombo husina kunaka uye kukanganisa muhuwandu hwekutenderera kutenderera.

4. Kudzivirirwa kwekudzivirira pakati pema windings uye kudzivirira kwekudzivirira pakati pemhepo nemabhomba kunogona kuyerwa ne:

1) Motokari ye380V inopimwa nemegohmmeter ine kuyerwa kwe 0-500 megohms kana 0-1000 megohms.Kudzivirira kwayo kwekudzivirira hakugoni kuva pasi pe 0.5 megohms.

2) Shandisa megohmmeter ine chiyero chekuyera kubva 0-2000 megohms kuyera iyo mota ine voltage yakakwira.Kudzivirira kwayo kwekudzivirira hakugone kuderera kupfuura 10-20 megohms.
