Kana iyo mota inoshandura simba remagetsi kuita mechanical simba, inorasikirwawo nechikamu chesimba pachayo. Kazhinji, kurasikirwa kwemotokari kunogona kukamurwa kuita zvikamu zvitatu: kurasikirwa kwakasiyana, kurasikirwa kwakagadziriswa uye kurasika kurasikirwa.

1. Kurasikirwa kwakasiyana kunosiyana nemutoro, kusanganisira stator resistance loss (copper loss), rotor resistance loss uye brush resistance loss.

2. Kurasikirwa kwakagadziriswa kwakasununguka pamutoro, kusanganisira kurasikirwa kwepakati uye kurasikirwa kwemagetsi.Kurasika kwesimbi kunoumbwa nekurasikirwa kwe hysteresis uye kurasikirwa kwazvino eddy, iyo yakaenzana neskweya yevoltiji, uye kurasikirwa kwehysteresis zvakare kunopesana ne frequency.

3. Kumwe kurasikirwa kwakarasika ndiko kurasikirwa kwemagetsi uye kumwe kurasikirwa, kusanganisira kurasikirwa kwe friction yemabheri uye kurasikirwa kwemhepo kunokonzerwa nekutenderera kwemafeni uye rotor.

Motor Kurasikirwa Classification

Matanho akati wandei ekudzikisa Kurasikirwa kweMotor

1 Stator kurasikirwa

Nzira huru dzekudzikisa iyo I ^ 2R kurasikirwa kwemota stator ndeidzi:

1. Wedzera iyo yakayambuka-chikamu nzvimbo ye stator slot. Pasi peyakaenzana yekunze dhayamita ye stator, kuwedzera iyo muchinjiko-chikamu nharaunda ye stator slot kunoderedza iyo magineti yedunhu nzvimbo uye kuwedzera magineti density yemeno.

2. Wedzerai yakazara slot ratio ye stator slots, iyo iri nani kune yakaderera-voltage madiki motors. Kushandisa iyo yakanakisa mhepo uye saizi yekuisa uye waya yakakura muchinjiko-chikamu nzvimbo inogona kuwedzera yakazara slot reshiyo ye stator.

3. Edza kupfupisa urefu hwekupedzisira kwe stator winding. Kurasika kweiyo stator inopeta magumo kunoverengera 1/4 kusvika 1/2 yekurasikirwa kwese kwemhepo. Kuderedza kureba kwekuguma kwemhepo kunogona kuvandudza kushanda kwemotokari.Miedzo inoratidza kuti kureba kwekupedzisira kunoderedzwa ne20% uye kurasikirwa kunoderedzwa ne10%.

2 Rotor kurasikirwa

I ^ 2R kurasikirwa kwemotokari yemotokari kunonyanya kuenderana nerotor ikozvino uye rotor resistance. Nzira dzekuchengetedza simba dzinoenderana ndedzinotevera:

1. Deredza rotor ikozvino, iyo inogona kufungidzirwa maererano nekuwedzera kwevheti uye simba remagetsi.

2. Wedzera nzvimbo yemuchinjikwa-chikamu che rotor slot.

3. Deredza kupikisa kwerotor winding, sekushandisa waya dzakakora uye zvinhu zvine kushomeka kwakaderera, izvo zvinonyanya kukosha kune madiki mota, nekuti mamotor madiki anowanzo kukanda aluminium rotor, kana yakakandwa copper rotor ikashandiswa, kurasikirwa kwese kwe mota inogona kudzikiswa ne10% ～15%, asi yanhasi yakakandwa yemhangura rotor inoda yakanyanya tembiricha yekugadzira uye tekinoroji haisati yazivikanwa, uye mutengo wayo uri 15% kusvika 20% yakakwira kupfuura iyo yekukanda aluminium rotor.

3 Kurasikirwa kukuru

Iko kurasikirwa kwesimbi kwemota kunogona kuderedzwa nematanho anotevera:

1. Deredzai magineti density uye kuwedzera kureba kwesimbi musimboti kuderedza magineti flux density, asi huwandu hwesimbi hunoshandiswa mumotokari hunowedzera zvinoenderana.

2. Deredza hukuru hwesimbi yesimbi kuderedza kurasikirwa kweiyo induced current. Semuenzaniso, kutsiva inopisa-yakakungurutswa silicon simbi pepa neinotonhora-yakakungurutswa silicon simbi inogona kuderedza ukobvu hwesilicon simbi sheet, asi simbi yakatetepa ichawedzera huwandu hwesimbi uye mutengo wekugadzira mota.

3. Shandisa inotonhora-yakakungurutswa silicon simbi pepa ane yakanaka magineti permeability kuderedza hysteresis kurasikirwa.

4. Gamuchira high-performance iron chip insulation coating.

5. Kupisa kupisa uye teknolojia yekugadzira, iyo yakasara kushungurudzika mushure mekugadzirisa simbi yesimbi ichakanganisa zvakanyanya kurasikirwa kwemotokari. Paunenge uchigadzira iyo silicon simbi pepa, iyo yekucheka nzira uye punching shear stress ine yakakura kukanganisa pakurasikirwa kwepakati.Kucheka nenzira inotenderedza yesilicon simbi pepa uye kupisa kurapwa kwesilicon simbi yekubaya pepa kunogona kuderedza kurasikirwa ne10% kusvika 20%.

4 Kurasika kurasikirwa

Nhasi, kunzwisisa kwekurasikirwa kwemotokari kuchiri mudanho rekutsvagisa. Dzimwe dzenzira huru dzekudzikisa kurasikirwa dzakarasika nhasi ndeidzi:

1. Shandisa kupisa kupisa uye kupedzisa kuderedza pfupi-circuit panzvimbo ye rotor.

2. Insulation kurapwa mukati memukati we rotor slot.

3. Deredza harmonics nekuvandudza stator winding design.

4. Kuvandudza dhizaini yerotor slot coordination uye kuderedza harmonics, kuwedzera stator uye rotor cogging, gadzira rotor slot shape seyakarerekera slots, uye shandisa dzakatevedzana-yakabatana sinusoidal windings, yakapararira windings uye pfupi-kure-mamhepo mhepo kuderedza zvakanyanya-yakarongeka harmonics. ; Kushandisa magineti slot mud kana magineti slot wedge kutsiva yechinyakare insulating slot wedge uye kuzadza slot yemota stator iron core ine magineti slot madhaka inzira inoshanda yekudzikisa kumwe kurasikirwa kwarasika.

5 mhepo kurasikirwa

Kurasikirwa kwemhepo kunokonzeresa 25% yekurasikirwa kwese kwemota, iyo inofanirwa kupihwa kutariswa kwakakodzera.Kurasikirwa kwefriction kunonyanya kukonzerwa nemabheya uye zvisimbiso, izvo zvinogona kuderedzwa nematanho anotevera:

1. Deredza ukuru hwe shaft, asi sangana nezvinodiwa zvekubuda torque uye rotor dynamics.

2. Shandisa mabhengi epamusoro-soro.

3. Shandisa inobudirira lubrication system uye lubricant.

4. Adopt advanced sealing tekinoroji.
