Kushandisa Anti-Eddy Current Magnets kuvandudza iyo High-Speed ​​Motors

Nhanganyaya:

Kune aerospace, mota, kana maindasitiri otomatiki, kugona kwemamota anomhanya kwakakosha. Zvisinei, kukurumidza kukuru nguva dzose kunoguma nepamusoroeddy currentsuye zvozokonzera kurasikirwa kwesimba uye kupisa zvakanyanya, izvo zvinokanganisa kushanda kwemota nekufamba kwenguva.

Ndosakaanti-eddy ikozvino maginetiszvave zvakakosha. Aya magineti anobatsira kudzora eddy currents, kuchengetedza mamotor kupisa uye kumhanya zvakanyanya-kunyanya mumagineti anotakura mota nemamotor anotakura mweya. Muchikamu chino, tichatsanangura kuti tekinoroji iyi inoshanda sei uye nei zvigadzirwa zve“MagnetPower”inonyanya kukodzera, nekuda kwekudzivirira kwavo kwakanyanya uye chizvarwa chekupisa.

1. The Eddy Currents

Eddy currents akaunzwa na“MagnetPower”munhau dzekare).

Mumamota anomhanya-mhanya, seaya anoshandiswa muaerospace kana compressors (Mutsetse wekumhanya ≥ 200m/s) , eddy currents inogona kuva dambudziko guru. Vanoumba mukati me rotors uye stators sezvo magnetic field inoshanduka nokukurumidza.

Eddy currents haisi kungokanganisa kudiki; vanogona kuderedza kushanda kwemotokari uye vanogona kutokonzera kukanganisa nekufamba kwenguva. Zvinoratidzwa zvinotevera:

• Kunyanya Kupisa: Eddy mafungu anoburitsa kupisa, izvo zvinowedzera kushushikana pane mota zvikamu. Semuenzaniso, iyo Irreversible magineti kurasikirwa kwemagineti echigarire NdFeB kana SmCo zvinogara zvichiitika nekuda kwekupisa kwakanyanya.
• Kupera Kwesimba: kushanda zvakanaka kwemota kwakadzikira nekuti simba raigona kugonesa mota rinoparara mukugadzira aya eddy currents.

2. Sei Anti-Eddy Current magineti Anobatsira

Anti-eddy magineti emazuva anodzakagadzirirwa kugadzirisa nyaya iyi zvakanangana. Nekudzikamisa kuti sei uye kupi eddy mafungu anoumba, ivo vanove nechokwadi chekuti mota inomhanya zvakanyanya uye inogara ichitonhorera. Imwe nzira inoshanda yekuvhara eddy currents ndeyekugadzira magineti mune lamination chimiro. Iyi nzira inogona kutyora iyo eddy ikozvino nzira, uyezve inodzivirira yakakura, inotenderera inotenderera kubva pakuumba.

3. Sei MagnetPower Tech kuti Assemblies Ideal nokuda High-Speed ​​Motors

Zvino, ngatinyure mune zvakanakira zvakanakiraMagnetPower'santi-eddy magungano emazuva ano. Aya magungano akakwana kune magineti anotakura mota uye mhepo inotakura mota, inopa musanganiswa wepamusoro resistivity, yakaderera kupisa chizvarwa, uye yakawedzera mota hupenyu.

3.1 High Resistivity = Maximum Efficiency

Iwo magineti anodzivirira eddy anogadzirwa ne "Magnet Power" ndeye kushandisa insulating glue pakati pezvikamu zvemagineti akatsemuka, anowedzera kupikisa kwemagetsi, pamusoro pe2MΩ · cm. Inoshanda kuputsa nzira ye eddy ikozvino. Nokudaro, kupisa hakusi nyore kugadzirwa. Izvi zvinonyanya kukosha mumagineti anotakura mota. Nekudzikisa kupisa, magineti eMagnetPower anovimbisa kuti mota dzinoramba dzichimhanya zvakanaka nekumhanya kwakanyanya pasina njodzi yekupisa. Zvakafanana nokudamhepo inotakura injini-kupisa kwakadzika kunochengetedza mukaha wemhepo pakati pe rotor uye stator yakagadzikana, iyo ndiyo inonyanya kukosha yekururama.

3.2 High magineti flux

Iwo magineti anogadzirwa nehupamhi hwe1mm uye anoratidza yakaonda kwazvo insulation layer ye 0.03mm. Izvi zvinochengeta huwandu hweglue hudiki uye huwandu hwemagineti hwakakura sezvinobvira.

3.3 mutengo wakaderera

Iyi nzira zvakare inodzikisira zvikumbiro zvekumanikidza uye mutengo uchiwedzera kugadzikana kwekupisa, Kunyanya kune NdFeB magineti. Kana tembiricha ye rotor ichigona kudzikiswa kubva pa180 ℃ kusvika 100 ℃, Giredhi remagineti rinogona kuchinjwa kubva paEH kuenda kuSH. Izvi zvinoreva kuti mutengo wemagineti unogona kudzikiswa nehafu.

4. Magineti eMagnetPower anoita sei muHigh-Speed ​​Motors

Ngatitarisei maitiro eMagnetPower's anti-eddy azvino magineti mune magineti anotakura mota uye mhepo inotakura mota.

4.1 Magnetic Bearing Motors: Kugadzikana paKumhanya Kwepamusoro

Mune magineti anotakura mota, magineti inotakura inochengeta rotor yakamiswa, ichiibvumira kutenderera pasina kubata chero mamwe mativi. Asi nekuda kwesimba rakakura (kupfuura 200kW) uye kumhanya kwakanyanya (kupfuura 150m/s, kana kupfuura 25000RPM), iyo eddy ikozvino haisi nyore kudzora. Fig.2 inoratidza rotor ine kumhanya kwe30000RPM. Nekuda kwekunyanya kurasikirwa kwazvino, kupisa kukuru kwakagadzirwa, zvichiita kuti rotor iwane tembiricha yepamusoro inodarika 500°C.

MagnetPower's magineti anobatsira kudzivirira izvi nekudzikisa eddy ikozvino kuumbwa. Kupisa kwe rotor yakagadziridzwa hakuna kudarika 200 ℃ mumamiriro ekushanda akafanana.3

Fig.2 rotor mushure mekuedzwa nekumhanya kwe30000RPM.

4.2 Mhepo Inotakura Motokari: Kururamisa paKumhanya Kwepamusoro

Mhepo inotakura mota dzinoshandisa firimu rakatetepa remhepo rinogadzirwa nekumhanya kukuru kutenderera kutsigira rotor. Idzi mota dzakagadzirwa kuti dzishande nekumhanya kwakanyanya, kunyangwe kusvika ku200,000RPM, zvine humbowo hunoshamisa. Nekudaro, eddy mafungu anogona kukanganisa neicho chaicho nekugadzira kupisa kwakanyanya uye kukanganisa gap remhepo.

Iine magineti eMagnetPower, eddy currents anodzikiswa, zvinoreva kuti mota inogara ichitonhorera uye inochengetedza iyo chaiyo mhepo gap inodiwa kune yakakwirira-kuita maapplication seHydrogen fuel cell compressor uye blower.

Mhedziso

Kana zvasvika kune akakwira-kumhanya mota, kudzikisira kurasikirwa kwesimba uye kudzora kupisa kupisa ndiko kwakakosha mukuvandudza mashandiro uye kuwedzera hupenyu hwemidziyo yako. Ndipo panopinda MagnetPower's anti-eddy azvino magineti.

Nekuda kwekushandiswa kwezvinhu zvinodzivirira zvakanyanya, dhizaini yakangwara senge segmentation uye lamination, uye tarisiro yekudzikisa eddy currents, magungano aya anobatsira mota kuti dzimhanye zvinotonhorera, zvine hungwaru, uye kwenguva refu. Ingave mune magineti anotakura mota, mhepo inotakura mota, kana zvimwe zvekumhanya-mhanya, MagnetPower iri kusunda miganhu yezvinogoneka mukushanda kwemota uye kuvimbika.
