Mhedzisiro yeIron Core Stress paKushanda kweMagnet Motors Dzinogara Dzose
Kufambira mberi nekukurumidza kwehupfumi kwakasimudzirawo hunyanzvi hweindasitiri yemagetsi emagetsi anogara kwenguva refu, zvichiisa zvinodiwa zvepamusoro zvekushanda kwemotokari, zviyero zvehunyanzvi, uye kugadzikana kwekushanda kwechigadzirwa. Kuti mota dzemagetsi emagetsi anogara kwenguva refu dzikure mumunda wakakura wekushandiswa, zvakakosha kusimbisa mashandiro akakodzera kubva pazvinhu zvese, kuitira kuti zviratidzo zvemhando yepamusoro uye mashandiro emota zvigone kusvika padanho repamusoro.
Kune mota dzinoshandisa magineti zvinogara kwenguva refu, musimboti wesimbi chinhu chakakosha zvikuru mukati memota. Pakusarudza zvinhu zvesimbi zvinoshandisa magineti, zvakakosha kufunga zvizere kana simba remagineti richigona kusangana nezvinodiwa zvemota dzinoshandisa magineti zvinogara kwenguva refu. Kazhinji, simbi yemagetsi inosarudzwa sechinhu chikuru chemota dzinoshandisa magineti zvinogara kwenguva refu, uye chikonzero chikuru ndechekuti simbi yemagetsi ine simba remagineti rakanaka.
Kusarudzwa kwezvinhu zvemota zvine simba guru pakushanda kwese uye kudzora mari yemota dzemagineti dzinogara dziripo. Munguva yekugadzira, kuunganidza, uye kushanda kwepamutemo kwemota dzemagineti dzinogara dziripo, mamwe matambudziko achavapo pamota. Zvisinei, kuvapo kwekumanikidzwa kuchakanganisa zvakananga mafambiro emagineti esimbi yemagetsi, zvichiita kuti mafambiro emagineti adzike kusvika padanho rakasiyana, saka mashandiro emota dzemagineti dzinogara dziripo achadzikira, uye zvichawedzera kurasikirwa kwemota.
Mukugadzira nekugadzira mota dzemagineti dzinogara kwenguva refu, zvinodiwa pakusarudza nekushandisa zvinhu zviri kuramba zvichikwira, zvichisvika padanho repamusoro uye mwero wekushanda kwezvinhu. Sechinhu chikuru chemota dzemagineti dzinogara kwenguva refu, simbi yemagetsi inofanira kusangana nezvinodiwa zvekururama kwakanyanya mumatekinoroji akakodzera ekushandisa uye kuverenga kwakarurama kurasikirwa kwesimbi kuitira kuti isangane nezvinodiwa chaizvo.
Nzira yechinyakare yekugadzira mota inoshandiswa kuverenga hunhu hwemagetsi hwesimbi yemagetsi haina kururama, nekuti nzira idzi dzechinyakare dzinonyanya kushandiswa mumamiriro ezvinhu echinyakare, uye mhedzisiro yekuverenga ichave nekutsauka kukuru. Nokudaro, nzira itsva yekuverenga inodiwa kuti iverenge nemazvo magnetic conductivity uye kurasikirwa kwesimbi yesimbi yemagetsi pasi pemamiriro esimba rekumanikidzwa, kuitira kuti mwero wekushandiswa kwezvinhu zvesimbi zvakakwirira, uye zviratidzo zvekushanda zvakaita sekushanda kwemamota emagneti anogara kwenguva refu zvisvike padanho repamusoro.
Zheng Yong nevamwe vaongorori vakatarisa pamhedzisiro yekushushikana kwepakati pakushanda kwemamota emagneti asingaperi, uye vakabatanidza ongororo yekuedza kuti vaongorore mashandiro akakodzera esimba remagneti rekumanikidzwa uye mashandiro ekurasikirwa nesimbi yesimbi yezvinhu zvemagneti zvekusingaperi. Kushushikana pasimbi yesimbi yemota yemagneti isingaperi mumamiriro ekushanda kunokonzerwa nezvinhu zvakasiyana-siyana zvekushushikana, uye sosi yega yega yekushushikana inoratidza zvinhu zvakasiyana zvachose.
Kubva pamaonero echimiro chekumanikidzwa kwe stator core ye permanent magnet motors, manyuko ekuumbwa kwayo anosanganisira kupwanya, kutsvedza, kukanda, kusanganisa kupindira kwe casing, nezvimwewo. Mhedzisiro yekumanikidzwa inokonzerwa nekusanganiswa kupindira kwe casing ine nzvimbo yakakura uye yakakosha ye impact. Kune rotor ye permanent magnet motor, manyuko makuru ekumanikidzwa kwainotakura anosanganisira thermal stress, centrifugal force, electromagnetic force, nezvimwewo. Zvichienzaniswa ne mamota akajairwa, kumhanya kwakajairika kwe permanent magnet motor kwakakwira, uye magnetic isolation structure yakaiswawo pa rotor core.
Saka, kushushikana kwepakati pemagineti ndiko kunokonzera kushushikana kukuru. Kushushikana kwepakati pemagineti kunokonzerwa nekupindira kwechikamu chemagetsi chemagetsi chisingaperi kunonyanya kuitika muchimiro chekumanikidzwa, uye nzvimbo yayo yekushanda yakabatana mujoko remudziyo wemagetsi, negwara rekumanikidzwa richiratidzwa sedenderedzwa retangential. Hunhu hwekumanikidzwa hunoumbwa nesimba repakati pemagineti remagetsi rinogara riripo isimba rekumanikidzwa, iro rinoshanda zvakanyanya pamudziyo wesimbi werotor. Kushushikana kwakanyanya kwepakati pemagineti kunoshanda pamharadzano yebhiriji remagetsi remagetsi rinogara riripo uye rib rekusimbisa, zvichiita kuti zvive nyore kuti kuderera kwebasa kuitike munzvimbo iyi.
Mhedzisiro yeIron Core Stress paMagnetic Field yePermanent Magnet Motors
Pakuongorora shanduko mu magnetic density yezvikamu zvakakosha zve permanent magnet motors, zvakaonekwa kuti pasi pesimba re saturation, hapana shanduko yakakura mu magnetic density pa reinforcement ribs uye magnetic isolation bridges ye motor rotor. Magnetic density ye stator uye main magnetic circuit ye motor inosiyana zvakanyanya. Izvi zvinogona zvakare kutsanangura mhedzisiro ye core stress pakugoverwa kwe magnetic density uye magnetic conductivity ye motor panguva yekushanda kwe permanent magnet motor.
Migumisiro Yokushushikana Pakurasikirwa Kwepfungwa
Nekuda kwekumanikidzwa, kumanikidzwa kwekumanikidzwa pajoko remota yemagnet inogara kwenguva refu kuchave kwakabatana zvakanyanya, zvichikonzera kurasikirwa kukuru uye kudzikira kwekushanda. Pane dambudziko guru rekurasikirwa nesimbi pajoko remota yemagnet inogara kwenguva refu, kunyanya panosangana mazino estator nejoko, uko kurasikirwa nesimbi kunowedzera zvakanyanya nekuda kwekumanikidzwa. Tsvagiridzo yakawana kuburikidza nekuverenga kuti kurasikirwa nesimbi pamota dzemagnet inogara kwenguva refu kwakawedzera ne40% -50% nekuda kwekumanikidzwa kwekumanikidzwa, izvo zvichiri kushamisa, zvichikonzera kuwedzera kukuru mukurasikirwa kwese kwemota dzemagnet inogara kwenguva refu. Kuburikidza nekuongorora, zvinogonawo kuwanikwa kuti kurasikirwa nesimbi pamota ndiyo nzira huru yekurasikirwa kunokonzerwa nekumanikidzwa kwekumanikidzwa pakuumbwa kwemota yesimbi inogara kwenguva refu. Kune rotor yemota, kana simbi iri pasi pekumanikidzwa kwekumanikidzwa panguva yekushanda, haingowedzeri kurasikirwa nesimbi chete, asi ichavawo nemhedzisiro yekuvandudza.
Mhedzisiro Yekushushikana Pakupinza Kwemhepo Nekutenderera Kwemhepo
Kushanda kwesimba remagetsi rinoita kuti musimboti wesimbi udzikire pasi pemamiriro ekumanikidzwa kwesimbi, uye shaft inductance yayo inodzikira kusvika pamwero wakati. Kunyanya, tichiongorora magnetic circuit yemota yemagineti inogara iripo, shaft magnetic circuit inonyanya kusanganisira zvikamu zvitatu: mhepo isina chinhu, magneti inogara iripo, uye stator rotor iron core. Pakati pazvo, permanent magnet ndiyo inonyanya kukosha. Zvichibva pachikonzero ichi, kana magnetic induction performance yesimbi inogara iripo inochinja, haigone kukonzera shanduko huru mu shaft inductance.
Chikamu che shaft magnetic circuit chinoumbwa ne air gap uye stator rotor core ye permanent magnet motor idiki zvikuru pane magnetic resistance ye permanent magnet. Tichifunga nezve simba re core stress, magnetic induction performance inoderera uye shaft inductance inoderera zvakanyanya. Ongorora kukanganiswa kwe stress magnetic properties pa iron core ye permanent magnet motor. Sezvo magnetic induction performance ye motor core ichiderera, magnetic linkage ye motor inoderera, uye electromagnetic torque ye permanent magnet motor inodererawo.
