Iyo 4-pole dhizaini yakasimba kupfuura iyo 2-pole yakaenzana, asi inogona zvakare kutora nzvimbo imwechete uye huremu.Greg Dutfield anobva ku maxon UK anotsanangura.
4-pole mota dzine zvakanakira pakusarudza micro DC mota dzekushandisa kubva kune aerospace kusvika kutsime rekuchera.Iyo 4-pole dhizaini yakasimba kupfuura iyo 2-pole yakaenzana, asi inogona zvakare kutora nzvimbo imwechete uye huremu.Greg Dutfield anobva ku maxon UK anotsanangura.
Kune DC mota inoda yakakwira torque ine huremu hwakaderera uye compactness, 4-pole mota inogona kunge iri sarudzo yakanyanya kunaka.4-pole mota dzinogona kutora tsoka yakafanana ne2-pole mota, asi inokwanisa kugadzira yakawanda torque.Izvo zvakakosha kuti uzive kuti mota ye4-pole ine simba zvakare kupfuura 2-pole mota yehukuru hwakafanana, zvichireva kuti inochengetedza kumhanya kwayo zvakanyanya kana mutoro ukaiswa.
Nhamba yematanda inoreva huwandu hwemapeya emagineti echigarire mumotor.Mota ine mapango maviri ine magineti akatarisana nekuchamhembe nekumaodzanyemba.Kana ikozvino inoshandiswa pakati pemapeya emapuranga, magnetic field inogadzirwa, zvichiita kuti rotor itenderere.Magadzirirwo emota anotangirawo kubva pa4-pole, kusanganisira mapaya maviri ematanda, kune akawanda-mapango dhizaini, kusanganisira anosvika gumi nemaviri.
Huwandu hwemapango chinhu chakakosha chekugadzira mota sezvo ichikanganisa kumhanya uye torque maitiro emota.Iyo yakaderera nhamba yematanda, iyo yakakwirira kumhanya kwemota.Izvi zvinodaro nekuti imwe neimwe yemagetsi kutenderera kwe rotor kunoenderana nekupedzwa kweiyo magnetic field cycle kune imwe neimwe mapango.Iyo mota ine magineti akawanda echigarire, ndiko kunowedzera mafambiro anodiwa, izvo zvinoreva kuti iyo nguva yakareba inotora rotor kuti ipedze kutenderera kwe360 °.Kumhanya kunopatsanurwa nehuwandu hwemapole pair pane yakatarwa frequency, saka uchifunga kuti 2-pole mota pa10,000 rpm, 4-pole mota inoburitsa 5000 rpm, mota yemapole matanhatu inomhanya pa3300 rpm, nezvimwewo d. ..
Mahombe mota anogona kugadzira torque yakawanda zvisinei nehuwandu hwemapango.Nekudaro, kuwedzera huwandu hwemapango kunogona kugadzira yakawanda torque pane mota yehukuru hwakafanana.Kana iri mota ine 4-pole mota, torque yayo inowedzerwa zvakanyanya neyakaomesesa dhizaini ine yakatetepa magineti yekudzoka nzira ichisiya imwe nzvimbo yemapaya maviri echigarire magineti mapango, uye kana iri maxon motors, ayo ane patent yakakora yakarukwa mhepo.
Kunyangwe mota ine 4-pole inogona kutora tsoka yakafanana neye 2-pole dhizaini, zvinofanirwa kucherechedzwa kuti kuwedzera kwehuwandu hwemapango kubva pa6 kusvika pa12 zvinoreva kuti saizi nehuremu hwefuremu hunofanirwa kuwedzera kusvika gadzirisa tambo yemhangura yakawedzerwa., iron uye magineti hazvidiwi.
Kusimba kwemota kunowanzo kutsanangurwa nekumhanya-torque gradient, zvichireva kuti mota ine simba inogona kubata kumhanya zvakanyanya kana mutoro ukaiswa.Iyo yekumhanyisa-torque gradient inoyerwa nekudzikira kwekumhanya pa1 mNm yemutoro.Nhamba dzakaderera uye magiredhi akapfava zvinoreva kuti injini ichakwanisa kuchengetedza kumhanya kwayo pasi pemutoro.
Imwe mota ine simba inogoneka nekuda kweiyo yakafanana dhizaini maficha ayo zvakare anobatsira kuti iwane yakakwirira torques, senge yakawandisa mamhepo uye kushandiswa kwezvakakwana zvinhu mukugadzira maitiro.Saka mota ye4-pole inovimbika kupfuura mota ye2-pole yehukuru hwakafanana.
Semuenzaniso, 4-pole maxon mota ine dhayamita ye22 mm ine kumhanya uye torque gradient ye19.4 rpm/mNm, zvinoreva kuti inongorasikirwa ne19.4 rpm pa1 mNm yega yega inoshandiswa, ukuwo 2- maxon pole mota ye saizi yakafanana ine kumhanya uye torque gradient ye110 rpm./mNm .Havasi vese vanogadzira mota vanosangana nekugadzira maxon uye zvinhu zvinodiwa, saka mamwe mabhureki e2-pole motors anogona kunge aine kumhanya kwakakwira uye torque gradients, zvichiratidza mota isina kusimba.
Aerospace applications inobatsira kubva mukuwedzera kwesimba uye kureruka kurema kwe4-pole mota.Aya hunhu anodiwawo kune anobatwa nemaoko maturusi emagetsi, ayo anowanzoda torque yakawanda kupfuura iyo 2-pole mota inogona kupa, asi ine huremu huremu uye idiki muhukuru.
Kuita kwe4-pole mota kwakakoshawo kune vanogadzira nharembozha.Marobhoti ane mavhiri kana anoteedzerwa anofanirwa kukunda nzvimbo yakaoma, zvipingamupinyi uye materu kana uchiongorora pombi dzeoiri negasi kana kutsvaga vanenge vawirwa nekudengenyeka kwenyika.4-pole mota dzinopa torque uye simba rinodiwa kukurira mitoro iyi, kubatsira vagadziri vemarobhoti enhare kuvaka compact uye huremu dhizaini.
Iyo diki saizi, yakasanganiswa neyakaderera kumhanya uye torque gradients, yakakoshawo kudzora zvakanaka muindasitiri yemafuta negesi.Kune iyi application, compact 2-pole mota haina simba rakakwana uye akawanda-pole mota akakurisa kune iyo bit yekuongorora nzvimbo, saka Maxon akagadzira 32mm 4-pole mota.
Mazhinji maapplication akakodzera 4-pole motors anoitika munzvimbo dzakanyanyisa kana mumamiriro ezvinhu anoda kugona kushanda pakupisa kwepamusoro, kudzvanywa uye kudedera.Semuenzaniso, mota dzinodzora zvakanaka dzinogona kushanda patembiricha inopfuura 200 ° C, nepo mota dzakaiswa mumotokari dzinozvimiririra dzepasi pemvura (AUVs) dzinoiswa mumatangi anodzvanywa akazara nemafuta.Iine mamwe madhizaini ekuwedzera senge maoko uye matekinoroji ekuvandudza kupisa kupisa, iyo compact 4-pole mota inogona kumira yakanyanyisa kushanda mamiriro kwenguva yakareba.
Nepo kutsanangurwa kwemota kwakakosha, dhizaini yeiyo yese dhiraivha system, kusanganisira gearbox, encoder, dhiraivha uye zvinodzora, zvinofanirwa kutariswa kukwirisa application.Pamusoro pekubvunza pamusoro pezvinotsanangurwa nemota, maxon mainjiniya anogona zvakare kushanda neOEM zvikwata zvekusimudzira kugadzira application-chaiyo yakazara madhiraivha masisitimu.
maxon ndiye anotungamira mutengesi weyakanyanya kurongeka brashe uye brushless DC servo motors uye madhiraivha.Aya mamotor anokura muhukuru kubva pa4mm kusvika 90mm uye anowanikwa kusvika pa500W.Isu tinosanganisa mota, giya uye DC mota zvinodzora kuita zvine hungwaru madhiraivha masisitimu anogona kugadzirwa kuti asangane nezvinodiwa chaizvo zvekushandisa kwevatengi vedu.
Zvinyorwa zvakanakisa zve 2022. Fekitori huru yepasta pasi rose inoratidza marobhoti akasanganiswa uye kugovera kwakasimba.
