Mhedzisiro yeIron Core Stress paKuita kwePermanent Magnet Motors
Iko kukurumidza kusimukira kwehupfumi kwakawedzera kusimudzira maitiro ehunyanzvi hwechigarire magineti mota indasitiri, ichiisa pamberi pepamusoro zvinodiwa zvekuita zvine chekuita nemota, hunyanzvi mazinga, uye kugadzikana kwekushanda kwechigadzirwa. Kuti magineti echigarire magineti akure munzvimbo yakafararira yekushandisa, zvinodikanwa kusimbisa mashandiro akakodzera kubva kune ese maficha, kuitira kuti iwo ese emhando uye zviratidziro zvemota zvisvike padanho repamusoro.
Kune echigarire magineti mota, iyo musimboti wesimbi chinhu chakakosha zvikuru mukati memota. Pakusarudzwa kwesimbi musimboti zvinhu, zvinodikanwa kuti utarise zvizere kana iyo magineti conductivity inogona kusangana nezvinodiwa zvekushanda zvechigarire magineti mota. Kazhinji, simbi yeMagetsi inosarudzwa seyakakosha magineti motors, uye chikonzero chikuru ndechekuti simbi yeMagetsi ine yakanaka magineti conductivity.
Kusarudzwa kwezvinhu zvemudhudhudhu zvine simba rakakosha pakuita kwese uye kudzora mutengo weanogara magineti mota. Munguva yekugadzira, kusangana, uye kushanda kwakarongeka kwemagineti echigarire mota, kumwe kushushikana kunoumba pamusimboti. Nekudaro, kuvepo kwekushushikana kuchakanganisa zvakananga iyo magineti conductivity yeMagetsi simbi pepa, zvichiita kuti magineti conductivity ideredze kune akasiyana madhigirii, saka kuita kwekusingaperi magineti mota kunodzikira, uye kuchawedzera kurasikirwa kwemota.
Mukugadzira uye kugadzirwa kwemagineti echigarire mota, izvo zvinodikanwa zvekusarudzwa uye kushandiswa kwezvinhu zviri kuramba zvichikwira nekukwira, kunyangwe padhuze nechiyero uye chiyero chekuita kwezvinhu. Seyakanyanya zvinhu zvechigarire magineti motors, simbi yeMagetsi inofanirwa kusangana nepamusoro-soro zvinodiwa muhunyanzvi hwekushandisa matekinoroji uye kuverenga kwakaringana kwekurasikirwa kwesimbi kuitira kuti isangane nezvido chaizvo.
Iyo yechinyakare mota dhizaini nzira inoshandiswa kuverenga iyo electromagnetic maitiro eMagetsi simbi zviri pachena kuti haina kururama, nekuti idzi dzakajairwa nzira dzinonyanya dzezvakajairwa mamiriro, uye mhedzisiro yekuverenga ichave nekutsauka kukuru. Naizvozvo, nzira nyowani yekuverenga inodiwa kuti uverenge nemagineti conductivity uye kurasikirwa kwesimbi kweMagetsi simbi pasi pekunetsekana kwemamiriro ezvinhu, kuitira kuti chiyero chekushandisa chesimbi musimboti zvinhu chikwirire, uye zviratidziro zvekuita senge kugona kwechigarire magineti motors kusvika. mwero wepamusoro.
Zheng Yong nevamwe vaongorori vakatarisa pane kukanganisa kwepakati kushushikana kwekuita kwechigarire magineti mota, uye nekubatanidza ongororo yekuongorora kuti iongorore nzira dzakakodzera dzekushushikana kwemagineti uye kushushikana kwesimbi kurasikirwa kuita kwechigarire magineti mota yepakati zvinhu. Kushushikana kwesimbi musimboti weanogara magineti mota pasi pemamiriro ekushanda kunopesvedzerwa neakasiyana masosi ekushushikana, uye imwe neimwe sosi yekushushikana inoratidza akawanda akasiyana zvachose.
Kubva pakuona kwekunetseka kwechimiro che stator core yekusingaperi magineti motors, zvitubu zvekuumbwa kwayo zvinosanganisira punching, riveting, lamination, interference assembly of the casing, etc. yakanyanya kukosha nzvimbo yekukanganisa. Kune rotor yeanogara magineti mota, izvo zvikuru zvinokonzeresa kushushikana kwainotakura zvinosanganisira thermal stress, centrifugal force, electromagnetic force, etc. Kana ichienzaniswa neajairwa mota, kumhanya kwakajairwa kwechigarire magineti mota yakakwira zvakanyanya, uye magineti yekuzviparadzanisa nevamwe. inoiswawo pane rotor core.
Nokudaro, centrifugal stress ndiyo inonyanya kukonzera kushungurudzika. Iyo stator musimboti kushushikana inogadzirwa nekukanganisa kusangana kwechigarire magineti mota casing inonyanya kuvepo muchimiro chekumanikidza kushushikana, uye nzvimbo yayo yekuita inonamirwa mujoko remota stator core, nekutungamira kwekushushikana kunoratidzwa seyakatenderera tangential. Iyo yekushushikana pfuma inoumbwa neiyo centrifugal simba rechigarire magineti mota rotor is tensile stress, iyo inenge ichiita zvakazara pane iron core ye rotor. Iyo yakanyanya centrifugal kusagadzikana inobata pamharadzano yeanogara magineti mota rotor magineti yekuzviparadzanisa nevamwe bhiriji uye inosimbisa mbabvu, zvichiita kuti zvive nyore kuti kuderedzwa kwekuita kuitike munzvimbo ino.
Mhedzisiro yeIron Core Stress paMagnetic Field yePermanent Magnet Motors
Kuongorora shanduko yemagineti density yezvikamu zvakakosha zvechigarire magineti mota, zvakaonekwa kuti pasi pesimba rekuzara, pakanga pasina shanduko yakakosha muhuwandu hwemagineti pambabvu dzekusimbisa uye mabhiriji ega ega ega emota rotor. Iyo magineti density ye stator uye huru magineti wedunhu remota inosiyana zvakanyanya. Izvi zvinogona zvakare kutsanangura mhedzisiro yekushushikana kwepakati pane iyo magineti density kugovera uye magineti conductivity yemota panguva yekushanda kwechigarire magineti mota.
Mhedzisiro yeStress pane Core Loss
Nekuda kwekushushikana, iyo yekumanikidza kushushikana pajoko rekusingaperi magineti mota stator ichave yakatarisana, zvichikonzera kurasikirwa kukuru uye kuderera kwekuita. Pane dambudziko rakakura rekurasikirwa nesimbi pajoko remagineti yekusingaperi mota stator, kunyanya pakusangana kwemazino e stator uye joko, uko kurasikirwa kwesimbi kunowedzera zvakanyanya nekuda kwekushushikana. Tsvagiridzo yakawana kuburikidza nekuverenga kuti kurasikirwa kwesimbi kwemagineti echigarire kwakawedzera ne40% -50% nekuda kwesimba rekumanikidza kushushikana, izvo zvichiri kushamisa, zvichikonzera kuwedzera kukuru kwekurasikirwa kwese kwekusingaperi magineti mota. Kuburikidza nekuongorora, inogonawo kuwanikwa kuti kurasikirwa kwesimbi kwemota ndiyo nzira huru yekurasikirwa kunokonzerwa nekurudziro yekumanikidza kudzvinyirira pakuumbwa kweiyo stator iron core. Kune iyo mota rotor, kana iyo iron core iri pasi pe centrifugal tensile stress panguva yekushanda, kwete chete haizowedzere kurasikirwa kwesimbi, asi zvakare ichava neimwe yekuvandudza maitiro.
Mhedzisiro yeStress pane Inductance uye Torque
Iyo magineti induction kuita kweiyo mota iron core inodzikira pasi pekunetsekana kweiyo iron core, uye yayo shaft inductance inodzikira kune imwe nhanho. Kunyanya, kuongorora iyo magineti yedunhu rechigarire magineti mota, iyo shaft magineti wedunhu inonyanya kusanganisira zvikamu zvitatu: mweya gap, magineti asingagumi, uye stator rotor iron core. Pakati pavo, magineti echigarire ndiyo inonyanya kukosha. Zvichienderana nechikonzero ichi, kana iyo magineti induction kuita kweiyo inogara magineti mota iron core inochinja, haigone kukonzera shanduko yakakosha mu shaft inductance.
Iyo shaft magineti yedunhu chikamu inoumbwa nemhepo gap uye iyo stator rotor musimboti wechigarire magineti mota idiki zvakanyanya pane remagineti kuramba magineti anogara. Tichifunga nezve pesvedzero yekushushikana kwepakati, iyo magineti induction performance inodzikira uye shaft inductance inoderera zvakanyanya. Ongorora kukanganisa kwekushushikana kwemagineti pane iyo iron musimboti weanogara magineti mota. Sezvo iyo magineti induction kuita kweiyo motor core inodzikira, iyo magineti yekubatanidza yemota inodzikira, uye iyo electromagnetic torque yeanogara magineti mota inodzikira zvakare.
