Sezvo kurasikirwa kwekugoverwa kwemotokari kunosiyana nehukuru hwemasimba uye nhamba yematanda, kuitira kuti tideredze kurasikirwa, tinofanira kuisa pfungwa pakutora matanho ezvikamu zvakakura zvekurasikirwa kwemasimba akasiyana uye nhamba dzepole. Dzimwe nzira dzekudzikisa kurasikirwa dzinotsanangurwa muchidimbu sezvizvi:

1. Wedzera zvinhu zvinobudirira kuderedza kupera kwemhepo uye kurasikirwa kwesimbi

Zvinoenderana neyakafanana musimboti wemotor, kana iyo electromagnetic mutoro ukaramba usina kuchinjika uye kurasikirwa kwemechani kusingatariswe, kurasikirwa kwemota kunenge kwakaenzana necube yehukuru hwemutsetse wemota, uye simba rekupinza remota rinenge. kuenzana nesimba rechina rekukura kwemutsara. Kubva pane izvi, hukama huri pakati pekuita uye kushandiswa kwezvinhu zvinobudirira kunogona kuenzaniswa. Kuti uwane nzvimbo yakakura pasi pemamwe saizi yekumisikidza mamiriro kuitira kuti zvimwe zvinobudirira zvigone kuiswa kuvandudza kushanda kwemota, saizi yekunze dhayamita ye stator punching inova chinhu chakakosha. Mukati meiyo yakafanana muchina base renji, maAmerican motors ane yakakura kuburitsa kupfuura eEuropean motors. Kuti ifambise kupisa kupisa uye kuderedza kukwira kwekushisa, mota dzeAmerica dzinowanzo shandisa stator punching ine madhayamita akakura ekunze, nepo mota dzeEurope dzinowanzo shandisa stator punching ine madhayamita madiki ekunze nekuda kwekudiwa kwezvinobuda muchimiro senge mota dzinoputika uye kuderedza huwandu hwemhangura inoshandiswa pakupera kwemhepo uye mari yekugadzira.

2. Shandisa zviri nani magineti uye maitiro matanho ekudzikisa kurasikirwa kwesimbi

Iyo magineti zvivakwa (magnetic permeability uye unit iron kurasikirwa) yepakati zvinhu zvine pesvedzero huru pakubudirira uye kumwe kuita kwemota. Panguva imwecheteyo, mari yezvinhu zvakakosha ndiyo chikamu chikuru chemutengo wemota. Naizvozvo, kusarudzwa kweakakodzera magineti zvinhu ndiyo kiyi yekugadzira uye kugadzira yakakwirira-inoshanda mota. Mune epamusoro-simba mota, kurasikirwa kwesimbi kunokonzeresa chikamu chikuru chekurasikirwa kwakazara. Naizvozvo, kudzikisa kukosha kwekurasikirwa kwechikamu cheiyo yakakosha zvinhu kuchabatsira kudzikisa kurasikirwa kwesimbi kwemota. Nekuda kwekugadzirwa uye kugadzirwa kwemota, kurasikirwa kwesimbi kwemota kunopfuura zvakanyanya kukosha kwakaverengerwa zvichienderana neyuniti iron kurasikirwa kukosha kwakapihwa nesimbi mill. Nokudaro, iyo unit iron kurasikirwa kukosha inowanzowedzerwa ne 1.5 ~ 2 nguva panguva yekugadzira kuti ione kuwedzera kwekurasikirwa kwesimbi.

Chikonzero chikuru chekuwedzera kwekurasikirwa kwesimbi ndechekuti iyo unit iron kurasikirwa kukosha kwechigayo chesimbi inowanikwa nekuyedza iyo strip zvinhu sampuli zvinoenderana neEpstein square denderedzwa nzira. Nekudaro, izvo zvinhu zvinoiswa pasi pekunetseka kukuru mushure mekurova, kuveura uye laminating, uye kurasikirwa kuchawedzera. Mukuwedzera, kuvapo kwezino rezino kunokonzera kuputika kwemhepo, izvo zvinotungamirira kune kusarasikirwa kwekuremerwa pamusoro pehupamhi hunokonzerwa nezino harmonic magnetic field. Izvi zvinotungamira kukuwedzera kukuru kwekurasikirwa kwesimbi kwemota mushure mekugadzirwa kwayo. Naizvozvo, mukuwedzera pakusarudza magineti ane yakaderera unit iron kurasikirwa, zvinodikanwa kudzora kumanikidza kwelamination uye kutora matanho anodiwa ekudzikisa kurasikirwa kwesimbi. Tichitarisa mutengo uye maitiro ekugadzirisa zvinhu, yakakwirira-giredhi silicon simbi mashiti uye silicon simbi mapepa akatetepa kupfuura 0.5mm haashandiswe zvakanyanya mukugadzirwa kwemhando yepamusoro-soro mota. Yakaderera-kabhoni silicon-isina magetsi simbi mashiti kana yakaderera-silicon inotonhora-yakakungurutswa silicon simbi mapepa anowanzo shandiswa. Vamwe vanogadzira mota diki dzeEurope vakashandisa silicon-isina magetsi simbi masheets ane unit iron kurasikirwa kukosha kwe6.5w/kg. Mumakore achangopfuura, zvigayo zvesimbi zvakatangisa Polycor420 yemagetsi simbi mapepa ane avhareji yekurasikirwa kwechikamu che4.0w/kg, kunyange yakaderera pane mamwe akaderera-silicon simbi mapepa. Izvo zvinhu zvakare zvine yakakwirira magineti permeability.

Mumakore achangopfuura, Japan yakagadzira simbi yakaderera-silicon inotonhora-yakakungurutswa simbi ine giredhi re50RMA350, ine shoma shoma yealuminium uye isingawanzo simbi yepasi yakawedzerwa pakuumbwa kwayo, nekudaro ichichengetedza yakakwirira magineti permeability ichideredza kurasikirwa, uye yayo. unit iron kurasikirwa kukosha ndeye 3.12w/kg. Izvi zvinogona kupa hwaro hwezvinhu zvakanaka hwekugadzira uye kukwidziridzwa kwemamota-anoshanda.

3. Deredza saizi ye fan kuti uderedze kurasikirwa kwemhepo

Kune yakakura simba 2-pole uye 4-pole mota, kukweshera kwemhepo kunoverengera chikamu chikuru. Semuenzaniso, kukwesha kwemhepo kwe90kW 2-pole mota inogona kusvika pa30% yekurasikirwa kwese. Kukwesha kwemhepo kunonyanya kuumbwa nesimba rinoshandiswa nefeni. Sezvo kurasikirwa kwekupisa kwemamota-anoshanda zvakanyanya kunowanzo kuderera, mhepo inotonhorera inogona kudzikiswa, uye nekudaro simba remhepo rinogona kudzikiswa. Iro simba rekufemesa rinenge rakaenzana nechina kusvika ku5th simba reiyo fan dhayamita. Naizvozvo, kana tembiricha ichikwira ichibvumira, kuderedza saizi ye fan kunogona kunyatso kudzikisa kukweshera kwemhepo. Pamusoro pezvo, dhizaini inonzwisisika yechimiro chekufemesa yakakoshawo pakuvandudza kufefetera zvakanaka uye kuderedza kukweshera kwemhepo. Miedzo yakaratidza kuti kukweshera kwemhepo kweyepamusoro-simba 2-pole chikamu chepamusoro-inoshanda mota inogona kudzikiswa ne30% kana ichienzaniswa neyakajairwa mota. Sezvo kurasikirwa kwemhepo kwakaderedzwa zvakanyanya uye hakudi yakawedzera mari yekuwedzera, kushandura dhizaini yefeni kazhinji ndeimwe yematanho makuru anotorwa kune ichi chikamu chepamusoro-inoshanda mota.

4. Deredza kurasikirwa kwakarasika kuburikidza nekugadzira uye maitiro ekugadzirisa

Kurasika kwakarasika kweasynchronous motors kunonyanya kukonzerwa nekurasikirwa kwepamusoro-frequency mu stator uye rotor cores uye windings inokonzerwa nepamusoro-order harmonics yemagnetic field. Kuti uderedze mutoro wakarasika kurasikirwa, iyo amplitude yechikamu chimwe nechimwe harmonic inogona kuderedzwa nekushandisa Y-Δ series-yakabatana sinusoidal windings kana mamwe ma-low-harmonic windings, nokudaro kuderedza kurasikirwa kwakarasika. Miedzo yakaratidza kuti kushandiswa kwe sinusoidal windings kunogona kuderedza kurasikirwa kwakarasika neanopfuura 30% paavhareji.

5. Kuvandudza kufa-casting process kuderedza rotor kurasikirwa

Nekudzora kudzvanywa, tembiricha uye gasi rekuburitsa nzira panguva yerotor aluminium casting process, iyo gasi mumarotor bars inogona kuderedzwa, nekudaro ichivandudza conductivity uye kuderedza kushandiswa kwealuminium ye rotor. Mumakore achangopfuura, United States yakabudirira kugadzira copper rotor die-casting equipment uye inofambirana nemaitiro, uye parizvino iri kuita diki-scale trial production. Masvomhu anoratidza kuti kana mhangura rotors akatsiva aruminiyamu rotors, rotor kurasikirwa kunogona kuderedzwa neanenge 38%.

6. Shandisa kombiyuta yekugadzirisa dhizaini kuderedza kurasikirwa nekuvandudza kushanda zvakanaka

Pamusoro pekuwedzera zvinhu, kuvandudza mashandiro ezvinhu uye kuvandudza maitiro, dhizaini yekombuta inoshandiswa kuona zvine mutsindo maparamendi akasiyana-siyana pasi pezvipingamupinyi zvemutengo, kuita, nezvimwe, kuitira kuti uwane iyo yakanyanya kunaka kuvandudza mukubudirira. Iko kushandiswa kwe optimization dhizaini kunogona kupfupisa zvakanyanya nguva yekugadzira mota uye kugadzirisa mhando yemota dhizaini.
