Chii Chinochengeta Parizvino kubva Kudonha kuburikidza neMotor Windings Yako?
Mukati memota yega yega yemagetsi, copper windings inotakura ikozvino. Vanogara mukati memitsetse yesimbi. Simbi inofambisa magetsi. Mhangura inofambisa magetsi. Kana vakabata, ikozvino inobuda. Zvikabudura zvemota. Kuita kunodonha. Pakupedzisira, injini inokundikana.
Chinhu chimwe chete chakamira pakati pemhangura nesimbi ipepa rakatetepa rezvinhu zvinonzibepa rekuvhara magetsi.
Hazvina kutaridzika zvakanyanya. Chikamu che millimeter ukobvu. Cheka kuita maumbirwo chaiwo. Svetera mukati meiyo slot mahwindi asati apinda. Asi pasina iyo, mota haishande.
Zvinoita Insulation Pepa Chaizvoizvo
Iyo stator musimboti inogadzirwa neakaturikidzana simbi laminations. Iyo mitsipa inoroverwa mavari. Injiniya anopinza chidimbu chebepa rekudzivirira mune yega yega slot, yakapetwa kuti iite mutsara madziro. Ipapo mamhepo anopinda mukati. Ipapo slot wedge inovhara kuvhura.
Bepa rine mabasa matatu. Kutanga, magetsi ekudzivirira - kumisa ikozvino kubva pakusvetuka kubva pamhangura kusvika kune simbi. Chechipiri, kuchengetedzwa kwemuchina - chengetedza ma windings pakatarisana nemicheto yakaoma yemarambi esimbi. Chechitatu, kutungamira kwekupisa - mamwe mamakisi anobatsira kuitisa kupisa kure nemhepo.
Kana bepa rikakundikana pane chimwe cheizvi, mota inotadza.

DMD ndiyo bhiza rekushanda. Iyo inovhara akawanda akajairwa mota nemutengo unonzwisisika. NMN inowedzera kuoma kwemagetsi. NHN inowedzera kupisa kupisa. Pepa reAramid rinowedzera ese ari maviri pamwe nepamusoro dielectric simba. Firimu rePolyimide nderenzvimbo dzakasimba.
Kunzwisisa Makirasi eTembiricha
Yese insulation material inotakura tembiricha rating. Uku hakusi kushambadzira. Iwo muganhu wakaedzwa.
| Kirasi | Maximum yekushanda tembiricha | Maitiro ekushandisa |
|---|---|---|
| Kirasi A | 105°C | Madhizaini ekare, akaderera-basa mota |
| Kirasi E | 120°C | Mafeni madiki, pombi |
| Kirasi B | 130°C | General chinangwa injini |
| Kirasi F | 155°C | Zvishandiso zvemagetsi, mota dzeindasitiri |
| Kirasi H | 180°C | EV mota, servo mota |
| Kirasi C | 220°C | High-performance, aerospace, basa rakanyanyisa |
Kusarudza kirasi isiri iyo kukanganisa kwakajairika. Kana mota ichimhanya pa140°C ichienderera, Kirasi B (130°C) ichakundikana. Kirasi F (155°C) ndiyo yakachengeteka sarudzo shoma.
Asi cherechedza: chiyero chekushisa chinoshanda kune kuenderera mberi kwekushanda. Tembiricha yepamusoro inogona kunge yakakwira. Mainjiniya akanaka anowedzera margin. Motokari inomhanya pa140°C inoenderera inofanira kuwana Class H insulation, kwete Kirasi F chete.

Mitanhatu Mibvunzo Inobvunza Vatengi
Ini ndingashandisa bepa rimwechete rekudzivirira kune mota dzangu dzese?
Kwete kazhinji. Mota dzakasiyana dzinomhanya patembiricha dzakasiyana uye voltages. Kumisikidza pane chimwe chinhu kunorerutsa hesera asi kunokumanikidza kuti ushandise yakakwira-giredhi zvinhu pane zvinodiwa kune mamwe mota, ichiwedzera mutengo. Kana kuti unoshandisa yakaderera-giredhi zvinhu uye ngozi kukundikana. Zvirinani kukwanirisa zvinhu zviviri kana zvitatu wozvifananidza nemashandisirwo.
Ndeupi musiyano uripo pakati peNMN neNHN?
Mutsara wepakati. NMN inoshandisa polyester firimu. NHN inoshandisa polyimide firimu. Polyimide inoshingirira tembiricha yakakwira. Kune mota dziri pasi pe155°C, NMN yakanaka. Kwe 155-180 ° C, sarudza NHN. Musiyano wemutengo une mwero.
Ko bepa gobvu rinogara richireva kuti insulation iri nani here?
Kwete nguva dzose. Dielectric simba rinowedzera nekukora, asi mechanical fit inova yakaoma. Pepa gobvu rinotora nzvimbo mukati meiyo slot. Nzvimbo iyoyo ingadai yakatakura mhangura yakawanda. Vagadziri vemota vanotengeserana kubva kuhukobvu hwekudzivirira vachitarisana nemhangura yekuzadza. Pepa rakatetepa rinobvumira yakawanda mhangura, simba repamusoro, asi inoda zvirinani kudzora maitiro.
Ndeipi sherufu yehupenyu hwebepa rekudzivirira?
Zvinoenderana nekuchengetedza mamiriro. Mukutanga kurongedza, mamiriro ekunze-anodzorwa, aramid bepa rinotora makore. Polyester-based zvinhu zvinogona kushatisa nekukurumidza. Njodzi huru kunyura unyoro uye kuchembera kwekunamira. Kana bepa rakachengetwa kweanopfuura makore maviri, edza sampuli usati washandisa.
Ndinoziva sei kana bepa remutengesi richienderana?
Bvunza Cpk data pane ukobvu. A Cpk ye1.33 kana yepamusoro zvinoreva kuti maitiro anokwanisa. Ndokumbirawo batch-to-batch bvunzo mishumo. Kana mutengesi asingakwanisi kugadzira izvi, havasi kudzora maitiro avo.
Ko bepa rekudzivirira rinogona kushandiswazve here?
Yakawanda ndeye thermoset kana yakakwira-performance thermoplastic. Kudzokorora zvakare kwakaoma. Mamwe mapepa earamid anogona kudzoserwa, asi maitiro acho haawanikwe zvakanyanya. Indasitiri yakatarisana nekudzikisa marara mukucheka nekuisa, kwete pakudzokorora kwevatengi.
Chirevo pamusoro pekuenderana neSlot Wedges
Insulation bepamitsara slot madziro. Iyo slot wedge inovhara kuvhura. Vanofanira kushanda pamwechete.
Wedge inodzvanya pabepa panovhura slot. Kana iyo pepa yakanyanya kupfava, wedge ichachera mairi. Kana bepa racho ranyanya brittle, rinotsemuka pawedge yekuonana point.
Kune mota dzeEV, mainjiniya mazhinji anobatanidza pepa rearamid nema aramid wedges. Mhuri yemidziyo yakafanana, kuwedzera kwekushisa kwakafanana uye maitiro emuchina. Kune general motors, bepa reDMD rine girazi-fiber wedges musanganiswa wakapupurirwa.
Paunenge uchiodha kubva kumutengesi, tsanangura zvinhu zviviri pamwe chete. Mutengesi anogona ipapo kufananidza masystem system.
