Injini ye "black tekinoroji" iyo inonyanya kushanda nesimba pane isingawanzo pasi magineti mota?Iyo "kumira kunze" synchronous kusada mota!

Rare Earth inozivikanwa se "industrial gold", uye inogona kusanganiswa nezvimwe zvinhu kuti igadzire zvinhu zvitsva zvakasiyana-siyana zvine zvinhu zvakasiyana, izvo zvinogona kuvandudza zvakanyanya kunaka uye kushanda kwezvimwe zvigadzirwa.

Sezvo chikamu cheChina chepasi risingawanzo chengetedzwa munzvimbo dzakachengetwa pasi rose chichidzikira, ivhu risingawanzowanikwi rave dura renyika;isingawanzo kuchera pasi uye kugadzirisa kwakadzika kuchaunza matambudziko ekukuvadzwa kwezvakatipoteredza…

Pakaiswa nyaya iyi ye "nyika" pamberi pesosaiti, mabhizinesi mazhinji aive achiri "parutivi", uku Gree akasarudza kushandisa "black tekinoroji" kutora "basa rakakosha".

Muna 1822, Faraday akaratidza kuti magetsi anogona kuchinjwa kuva kufamba kunotenderera;

Pasi pekuenderera kwekuita kwedzidziso iyi, yekutanga DC jenareta uye mota munhoroondo yevanhu yakabuda;

Siemens yakashandisa kutyaira motokari, uye ndokugadzira tram yenyika;

Edison akaedzawo neiyi mota, iyo yakaburitsa zvakanyanya simba rebhiza retrolley…

Nhasi, mota dzave chimwe chezvinhu zvakakosha zvemichina michina.Nekudaro, kugadzira mota dzechinyakare "hakuparadzaniswe kubva kune isingawanzo pasi".Muindasitiri yekugadzira mota, kuchengetedza simba uye kudzikisira emission ndiko kukurumidza.

"Nekuchinja kuri kuita nharaunda, takatanga kuona kuti basa rebhizinesi harisi rekuziva tekinoroji yakakosha chete, asiwo kusanganisa zvigadzirwa, nharaunda, uye zvinodikanwa zvekupona kwevanhu.Zvigadzirwa zvinogadzirwa nenzira iyi zvakakosha chaizvo. "——Dong Mingzhu

Naizvozvo, Gree Kaibon synchronous reluctance mota, isingade kushandisa magineti echigarire, haivimbi nezvinhu zvisingawanzo pasi, inochengetedza mutengo wekugadzira, inodzivirira kusvibiswa kwezvakatipoteredza kunokonzerwa nekuvandudzwa kwepasi isingawanzo dhipoziti, uye inopindura zvakanyanya kurudziro rwesimba. kuchengetedza uye kuderedza emission, zvakavapo.

Iyo synchronous kusada mota ine pfuma yekusada.Iyo inoteedzera musimboti wekushanda wekuti iyo magineti flux inogara ichivhara munzira yekushomeka kusada.Iyo torque inoumbwa neiyo magineti yekudhonza inogadzirwa nekuchinja kwekusada kunokonzerwa ne rotor munzvimbo dzakasiyana.Nekuita kwepamusoro uye mutengo wakaderera, Zvakanakira zvekuchengetedza simba zvinomira pachena mumapoka mazhinji emota.

Synchronous kusada mota VS yechinyakare DC mota: hapana mabhurashi uye mhete, yakapusa uye yakavimbika, nyore kugadzirisa;

Synchronous kusada mota VS yechinyakare AC asynchronous mota: Iko hakuna mhepo pa rotor, saka hapana rotor mhangura kurasikirwa, iyo inovandudza kushanda kwemota;

Synchronous kusada mota VS switched kusada mota: Iyo rotor pamusoro yakatsetseka uye kusada shanduko inoenderera, inodzivirira matambudziko e torque ripple uye ruzha rukuru panguva yekushanda kweiyo switched kusada mota;panguva imwecheteyo, iyo stator inonzi sine wave magnetic field, iyo iri nyore kudzora uye hardware platform Mature, nokudaro kuderedza mari yedhiraivha yekudzora system;

Synchronous kusada mota VS indasitiri mudiwa - inogara magineti synchronous mota: hapana magineti asingagumi pane rotor, mutengo wakaderera, unogadzirisa dambudziko rekusasimba kwemunda uye kurasikirwa kwemagineti, kushandiswa kwenguva refu, kushanda kwacho kwakanyatso kugadzikana, uye hapana zvakaomesesa zvinodiwa pavhoriyamu uye uremu Chiitiko chinogona kutsiva zvachose magineti echigarire synchronous mota.

Kuburikidza nekutsvagisa kwakazvimirira uye kusimudzira, Gree akatungamira mukuziva iyo yakakosha tekinoroji yesynchronous reluctance motors muChina, uye akatora zvinhu zvakakosha, akawanda akakwenenzverwa ekudzora mota nzira uye maitiro ekugadzira akadai sesimbi musimboti kugadzira uye mota kuungana, uye pakupedzisira tapa mimwe mikana.

1. Kuchengetedza magetsi nekuchengetedzwa kwezvakatipoteredza

Iyo synchronous reluctance mota inodzima magineti isingaperi, hapana dambudziko rekurasikirwa kwekushisa kwemagnetism, uye inogona kushanda zvakadzikama pasi pekupisa kwakanyanya.Sezvo isingade kushandisa magineti echigarire, haivimbi nezvinhu zvisingawanzo pasi, inochengetedza mutengo wekugadzira, uye inodzivirira kusvibiswa kwepasi isingawanzo dhipoziti kunharaunda.Chinodavidza kurudziro rwenyika rwekuchengetedza simba nekuderedza kuburitsa.Mukuwedzera, iyo rotor ye synchronous reluctance motor haidi kukandwa aluminium, iyo inoderedza zvakanyanya kushandiswa kwesimba mukugadzira maitiro.

2. Kushanda zvakanaka

Kuenzaniswa neasynchronous motors, synchronous reluctance motors inoshanda zvakanyanya, uye inogona kusvika pakusimba kwesimba pamusoro peIE4.Mutoro unotangira kubva pa25% kusvika ku120% ndewenzvimbo yepamusoro-soro.Kutsiva asynchronous motors kana YVF motors ine simba rimwechete rinogona kuvandudza zvakanyanya sisitimu simba rekushandisa uye nekuchengetedza zvakakwana magetsi.Mhedzisiro yacho yakakwira se30% kana kupfuura.

3. Kupindura nokukurumidza

Sezvo pasina squirrel cage bars uye magineti pane rotor, uye yakakura-nzvimbo yemagineti barriers slot mu rotor punching chidimbu, rotor ye synchronous kusada mota ine kanguva kadiki inertia.Pasi pezvakatemerwa zvakafanana, iyo nguva yeinertia yeiyo synchronous kusada mota ingori makumi matatu muzana yeiyo asynchronous mota.Kune zviitiko zvinoda kukwidziridza mhinduro yekugona, senge extruder, inogona kuderedza zvakanyanya kuwandisa kwakawanda zvinodiwa zvemota, kuderedza yazvino module maratidziro eiyo inverter, uye kuchengetedza simba.Mushandisi anodhura paunenge uchimhanyisa kugadzira.

4. Kuita zvakanaka zvakasiyana-siyana

Iyo synchronous reluctance mota inoshandisa iyo IEC yakajairwa casing (yakakanda aluminium kana cast iron casing inogona kushandiswa zvinoenderana nezvinodiwa nemushandisi), uye zviyero zvekuisa zvinoreva IEC yakajairwa furemu.Kune iyo yakakwira simba density synchronous kusada mota, sezvo furemu saizi iri 1-2 idiki pane yakajairwa matatu-chikamu asynchronous mota, vhoriyamu inoderedzwa nekupfuura 1/3, iyo inogona kugadziridzwa zviri nyore zvinoenderana nezvinodiwa nevatengi (kuisirwa kwakasiyana-siyana. nzira, Yekunze mudziyo interface dhizaini), zvakananga kutsiva iyo yekutanga mota.

5. Kuderera kwekushisa kunokwira

Sezvo iyo synchronous reluctance mota ichiri kuchengetedza diki rotor kurasikirwa kana ichimhanya neyakayerwa simba, tembiricha inokwira muganho yakakura.Inogona kuchengetedza nguva dzose torque kushanda mukati mehuwandu hwe10% -100% yakayerwa kumhanya, uye inogona kubvumira 1.2 nguva yekuremedza kushanda, iyo inoshandawo mu-self-fan inotonhorera chimiro.

6. Kuvimbika kwepamusoro uye kugadzirisa nyore

Iyo rotor haina njodzi ye demagnetization, yakaderera kurasikirwa, uye yakaderera kutakura tembiricha, kuve nechokwadi kugadzikana kwenguva refu kweiyo inotakura lubrication system uye kuwedzera hupenyu hweiyo insulation system;panguva imwecheteyo, rotor ine uremu huremu, nyore kuparadzanisa uye kuunganidza, uye yakachengeteka kuchengetedza.Kurarama zviri nyore nenzvimbo dzakaomarara uye tembiricha yekushanda yakanyanyisa.

Uye zvakare, mumashandisirwo akadai semapombi uye mafeni anoda chikamu chakayerwa mashandiro ekuremerwa, synchronous kusada mota dzinoenderana zvakanyanya nezvinodiwa nevashandisi zvekuchengetedza simba uye kuderedza kubuda.

Parizvino, Kaibang akanyorera anopfuura makumi maviri patents pane synchronous reluctance mota uye control tekinoroji, uye aona huwandu hukuru hwezvigadzirwa, zvine hunyanzvi zviratidzo zvinodarika zvigadzirwa zvinokwikwidza pasi rose.

Dzimwe nyanzvi dzakambotaura kuti: “Hakuna dambudziko risingawanzoitiki rokuchengetedza pasi munyika yangu.Inofanirwa kuenderana nemusika wepasirese uye kutora iyo 'kubvisa isingawanzo pasi tekinoroji' nzira nekushandisa synchronous kusada mota?Kana kushandisa zvakazara zvakanakira nyika isingawanzo kuvandudza mutengo wezvigadzirwa? ”

Gree anopa mhinduro - "ita kuti denga rive rakasvibira uye pasi rive rakasvibira", uye achiramba achirima uye achitevera kugona musynchronous kusada mota tekinoroji, nekuti kuchengetedza simba uye kuderedzwa kwekuburitsa haisi nyaya yenyika chete, ndeye hupenyu hwese hwepasi.hupenyu.Iri ibasa renyika huru uye zvakare basa rebhizinesi.
