SIMO: Nzira yekudzikisa sei kurasikirwa kweYE3 mota?

Kana simba remagetsi richishandurwa kuita mechanical simba, thelow-voltage motorpachayo icharasikirwawo nechikamu chesimba.LT SIMO motazvinotora iwe kuti unzwisise kurasikirwa kwemota. Kurasikirwa kweYE3 motainogona kukamurwa kuita zvikamu zvitatu: kurasikirwa kwakasiyana, kurasikirwa kwakagadziriswa uye kurasika kurasikirwa.

1. Kurasikirwa kwakasiyana kunosiyana nemutoro, kusanganisira stator kuramba kurasikirwa (kurasikirwa kwemhangura), rotor kuramba kurasikirwa uye brashi kuramba kurasikirwa.
2. Kurasikirwa kwakagadziriswa kwakasununguka pamutoro, kusanganisira kurasikirwa kwepakati uye kurasikirwa kwemagetsi. Iko kurasikirwa kwepakati kunosanganisira kurasikirwa kwe hysteresis uye kurasikirwa kwazvino eddy, izvo zvinoenderana ne square yevoltage uye inversely proportional kune frequency.
3. Kumwe kurasikirwa kwakarasika kurasikirwa kwemuchina uye kumwe kurasikirwa, kusanganisa kurasikirwa kwemabheri uye kurasikirwa nemhepo kunokonzerwa nekutenderera kwefani uye rotor.

A. Stator kurasikirwa

Nzira huru dzekudzikisa 1 ^ 2R kurasikirwa kweYE3 mota stator ndedzinotevera:

1. Pasi peiyo stator yekunze dhayamita, kuwedzera iyo muchinjiko-chikamu nharaunda ye stator slot kunoderedza iyo magineti yedunhu nzvimbo uye kuwedzera magineti density yezino.
2. Kune yakaderera-voltage madiki YE3 mota, wedzera yakazara slot reshiyo ye stator slot. Iyo yakazara slot rate ye stator inogona kukwidziridzwa nekutora zvirinani mhepo uye insulation saizi uye yakakura conductor mhiri-chikamu nzvimbo.
3. Kupera kwekurasikirwa kweiyo stator mhepo kunoverengera 1/4 ~ 1/2 yekurasikirwa kwese kwemhepo. Kudzikisa kureba kwekupera kwemhepo kunogona kuvandudza kushanda kweiyo YE3 mota. Migumisiro yekuedza inoratidza kuti kureba kwekupedzisira kunoderedzwa ne20% uye kurasikirwa kunoderedzwa ne10%.

B. Rotor kurasikirwa

Iyo 1 ^ 2R kurasikirwa kweYE3 motor rotor inonyanya kuenderana nerotor ikozvino uye rotor resistance. Nzira dzekuchengetedza simba dzinoenderana ndedzinotevera:

1. Iko rotor ikozvino inogona kuderedzwa kubva kumativi maviri: kuwedzera mhepo uye kuwedzera simba re YE3 motokari;
2. Wedzera nzvimbo ye-cross-sectional ye rotor slot;
3. Kune iyo YE3 mota, zvine musoro kudzikisa kupikisa kweiyo rotor mhepo (sekushandisa waya yakakora uye yakaderera-inodzivirira zvinhu) nekuti mamotor madiki anowanzo kukandwa aruminiyamu rotor. Kana yakakandwa copper rotor inoshandiswa, kurasikirwa kwese kwemotokari kunogona kuderedzwa ne10% -15%. Nekudaro, tembiricha yekugadzira yeyakakandwa copper rotor yakakwira zvakanyanya, tekinoroji haisati yave yakakurumbira, uye mutengo wayo ndeye 15% -20% yakakwirira kupfuura iyo yekukanda aluminium rotor.

C. Kurasikirwa kukuru

Iko kurasikirwa kwesimbi kwemota kunogona kuderedzwa nematanho anotevera:

1. Kuti udzikise magineti flux density, wedzera kureba kwesimbi musimboti kudzikisa iyo magineti flux density.
2. Semuyenzaniso, ukobvu hwesilicon simbi simbi inogona kudzikiswa nekushandisa inotonhora-yakakungurutswa silicon simbi pepa panzvimbo yekupisa-yakakungurutswa silicon simbi pepa, asi matete simbi machipisi anozowedzera huwandu hwesimbi machipisi uye mutengo wekugadzira mota.
3. Shandisa inotonhora-yakakungurutswa silicon simbi pepa ine yakanaka conductivity kuderedza hysteresis kurasikirwa.
4. Shandisa yakakwirira-inoshanda iron chip insulation coating.
5. Kurapa kwekupisa uye tekinoroji yekugadzira, iyo yakasara kushushikana mushure mesimbi chip processing ichakanganisa zvakanyanya kurasikirwa kwemota. Paunenge uchigadzira silicon simbi pepa, nzira yekucheka uye punching shear stress ine simba guru pakurasikirwa kwesimbi. Kucheka nenzira yekutenderedza yesilicon simbi pepa uye kupisa kurapa silicon simbi pepa kunogona kuderedza kurasikirwa ne10% ~ 20%.

D. Kurasika kurasikirwa

Parizvino, kunzwisisa kwekurasika kurasikirwa kweYE3AC mota ichiri mudanho rekutsvaga

1. Kurapa kwekupisa uye kupedzisa kunoshandiswa kuderedza rotor pamusoro pfupi pfupi.
2. Nzvimbo yemukati yerotor slot yakavharwa.
3. Yakavandudza dhizaini ye stator winding kuderedza harmonics.
4. Nokuvandudza dhizaini yekufananidza uye kuenzanisa kweiyo rotor slots, kuwedzera stator uye rotor slots, kugadzira rotor slots mu skew slots, uye kushandisa sinusoidal windings, yakapararira mhepo uye mapfupi mhepo windings munhevedzano, yakakwirira-yakarongeka harmonics inogona kuderedzwa zvikuru. Nekushandisa magineti gap mud kana magineti gap wedges pachinzvimbo chechinyakare insulating gap wedges, uye kuzadza mapundu eiyo stator core yemota nemagineti gap mud, inzira inoshanda yekudzikisa kumwe kurasikirwa kwarasika.

E. Kurasika kwemhepo

Kurasikirwa kwemhepo kunokanganisa 25% yekurasikirwa kwese kwemota uye inofanirwa kutariswa. Kurasikirwa kwefriction kunonyanya kukonzerwa nemabheya uye zvisimbiso, uye kurasikirwa kwekukwesha kunogona kuderedzwa nematanho anotevera:

1. Saizi ye shaft inofanira kuderedzwa zvakanyanya sezvinobvira, asi inofanirwa kusangana nezvinodiwa zvekubuda torque uye rotor dynamics.
2. Shandisa mabhengi epamusoro-soro.
3. Shandisa zvinobudirira masisitimu ekuzodza uye mafuta ekuzora.
4. Shandisa tekinoroji yekuisa chisimbiso.
