Idizayini ye-4-pole iqine kakhulu kunokulingana nezigxobo ezi-2, kodwa futhi ingathatha indawo efanayo nesisindo.UGreg Dutfield wase-maxon UK uyachaza.
Amamotho anezigxobo ezi-4 anezinzuzo ekukhetheni amamotho e-DC amancane ukuze asetshenziswe kusukela ku-aerospace kuya ekulawuleni ukubhoboza kahle.Idizayini ye-4-pole iqine kakhulu kunokulingana nezigxobo ezi-2, kodwa futhi ingathatha indawo efanayo nesisindo.UGreg Dutfield wase-maxon UK uyachaza.
Kumamotho e-DC adinga i-torque ephezulu enesisindo esiphansi nokubumbana, injini enezigxobo ezi-4 ingaba yisinqumo esingcono kakhulu.Amamotho anezigxobo ezi-4 angase athathe indawo efanayo namamotho anezigxobo ezi-2, kodwa ayakwazi ukukhiqiza i-torque eyengeziwe.Kubalulekile ukuqaphela ukuthi i-4-pole motor nayo inamandla kune-2-pole motor yobukhulu obuqhathaniswayo, okusho ukuthi igcina isivinini sayo ngokunembe kakhulu lapho kufakwa umthwalo.
Inombolo yezigxobo ibhekisela enanini lamapheya ozibuthe abangapheli kumotho.Injini enezigxobo ezimbili inozibuthe ababhekene nenyakatho naseningizimu.Uma i-current isetshenziswa phakathi kwamapheya ezigxobo, insimu kazibuthe iyadalwa, okwenza i-rotor ijikeleze.Ukucushwa kwezimoto nakho kusuka ku-4-pole, kufaka phakathi amapheya amabili ezigxobo, kuya kumiklamo ye-multi-pole, kuhlanganise nezigxobo ezifika kweziyi-12.
Inombolo yezigxobo iyisici esibalulekile sokwakhiwa kwemoto njengoba ithinta isivinini kanye nezici ze-torque zenjini.Lapho isibalo sezigxobo siphansi, sikhuphuka isivinini senjini.Lokhu kungenxa yokuthi ukujikeleza ngakunye kwemishini kwerotha kuncike ekuqedweni komjikelezo wamagnetic wepheya ngayinye yezigxobo.Uma amapheya amaningi ezibuthe ezihlala unomphela injini enawo, kudingeka imijikelezo yenjabulo eyengeziwe, okusho ukuthi uma ithatha isikhathi eside i-rotor ukuqedela ukuzungezisa okungu-360°.Ijubane lihlukaniswa ngenani lamapheya wezigxobo kumafrikhwensi amisiwe, ngakho-ke uma kucatshangwa ukuthi i-2-pole motor ku-10,000 rpm, i-4-pole motor izokhiqiza i-5000 rpm, motor-pole motor izogijima ku-3300 rpm, njll. ..
Amamotho amakhulu angakha i-torque eyengeziwe kungakhathaliseki inani lezigxobo.Kodwa-ke, ukwandisa inani lezigxobo kungakhiqiza i-torque eningi kune-motor enosayizi ofanayo.Endabeni yemoto enezigxobo ezi-4, i-torque yayo yanda kakhulu ngomklamo wayo ohlangene onendlela ezacile kazibuthe ebuyayo eshiya isikhala esengeziwe samapheya amabili ezigxobo zikazibuthe ezihlala njalo, futhi esimweni samamothoni ama-maxon, ukujikajika kwayo okuqinile okuqinisiwe okunelungelo lobunikazi.
Nakuba injini enezigxobo ezi-4 ingase ithathe indawo efanayo njengomklamo wezigxobo ezi-2, kufanele kuqashelwe ukuthi ukwanda okuqhubekayo kwenani lezigxobo kusuka ku-6 kuya ku-12 kusho ukuthi ubukhulu nesisindo sohlaka kufanele kukhuliswe ngokulingana ukuze vumela ikhebula yethusi eyengeziwe., insimbi nozibuthe akudingekile.
Amandla emoto ngokuvamile anqunywa i-speed-torque gradient, okusho ukuthi injini enamandla kakhulu ingabamba isivinini iqine kakhulu lapho kufakwa umthwalo.I-speed-torque gradient ikalwa ngokuncipha kwesivinini ngo-1 mNm ngamunye womthwalo.Izinombolo eziphansi kanye namamaki amancane kusho ukuthi injini izokwazi kangcono ukugcina isivinini sayo ngaphansi komthwalo.
Injini enamandla kakhulu ingenzeka ngenxa yezici ezifanayo zokuklama ezibuye ziyisize ifinyelele ama-torque aphezulu, njengama-winding amaningi kanye nokusetshenziswa kwezinto ezifanele enqubweni yokukhiqiza.Ngakho-ke i-4-pole motor inokwethenjelwa kakhulu kune-2-pole motor yobukhulu obufanayo.
Isibonelo, i-4-pole maxon motor enobubanzi obungu-22 mm inejubane kanye ne-torque gradient engu-19.4 rpm/mNm, okusho ukuthi ilahlekelwa kuphela ngu-19.4 rpm kuyo yonke i-1 mNm esetshenziswayo, kuyilapho i-2- a maxon pole motor ye- usayizi ofanayo unejubane kanye ne-torque gradient engu-110 rpm./mNm.Akubona bonke abakhiqizi bezimoto abahlangabezana nedizayini ye-maxon kanye nezidingo zezinto ezibonakalayo, ngakho-ke ezinye izinhlobo zamamotho anezigxobo ezi-2 zingase zibe nesivinini esiphezulu kanye nama-torque gradients, okubonisa injini ebuthakathaka.
Izinhlelo zokusebenza ze-Aerospace zizuza emandleni anda nesisindo esincane samamotho anezigxobo ezi-4.Lezi zimfanelo ziyadingeka futhi kumathuluzi wamandla abanjwe ngesandla, avame ukudinga i-torque engaphezu kwaleyo injini yezigxobo ezi-2, nokho anesisindo esilula futhi amancane ngosayizi.
Ukusebenza kwe-4-pole motor nakho kubalulekile kubakhiqizi bamarobhothi eselula.Amarobhothi anamasondo noma alandelelwe kufanele anqobe indawo emagebhugebhu, izithiyo kanye nemithambeka lapho ehlola amapayipi kawoyela negesi noma ethungatha izisulu zokuzamazama komhlaba.Amamotho angama-4-pole ahlinzeka ngetorque namandla adingekayo ukuze anqobe le mithwalo, esiza abakhiqizi bamarobhothi eselula bakhe amadizayini ahlangene futhi angasindi.
Usayizi omncane, ohlanganiswe nesivinini esiphansi kanye nama-torque gradients, nawo ubalulekile ekulawuleni kahle embonini kawoyela negesi.Kulolu hlelo lokusebenza, ama-compact 2-pole motors awanamandla ngokwanele futhi ama-multi-pole motors makhulu kakhulu endaweni yokuhlola kancane, ngakho uMaxon wakha injini engu-32mm 4-pole motor.
Izinhlelo zokusebenza eziningi ezifanele ama-motor 4-pole zenzeka ezindaweni ezibucayi noma ezimweni ezidinga amandla okusebenza ezingeni lokushisa eliphezulu, ukucindezela okukhulu nokudlidliza.Isibonelo, ama-motor control motors angasebenza emazingeni okushisa angaphezu kuka-200 ° C, kuyilapho amamotho afakwe ezimotweni ezizimele ngaphansi kwamanzi (AUVs) afakwe emathangeni agcwele uwoyela ngomfutho.Ngezici ezengeziwe zedizayini ezinjengemikhono nobuchwepheshe bokuthuthukisa ukunqanyulwa kokushisa, amamotho ahlangene angama-4-pole angakwazi ukumelana nezimo zokusebenza ezidlulele isikhathi eside.
Yize imininingwane yezimoto ibalulekile, ukwakheka kwayo yonke isistimu yokushayela, okuhlanganisa i-gearbox, i-encoder, idrayivu nezilawuli, kufanele kubhekwe njengokwandisa uhlelo lokusebenza.Ngokungeziwe ekubonisaneni ngokucaciswa kwezimoto, onjiniyela be-maxon bangaphinda basebenze namaqembu okuthuthukisa i-OEM ukuthuthukisa amasistimu okushayela aphelele aqondene nohlelo lokusebenza.
I-maxon ingumhlinzeki oholayo wokunemba okuphezulu okubhulashiwe nama-brushless DC servo motors namadrayivu.Lawa ma-motor ahluka ngosayizi ukusuka ku-4mm kuya ku-90mm futhi atholakala aze afike ku-500W.Sihlanganisa izilawuli zenjini, igiya kanye ne-DC kumasistimu okushayela ahlakaniphile angenziwa ngendlela oyifisayo ukuze ahlangabezane nezidingo ezithile zezicelo zamakhasimende ethu.
Ama-athikili angcono kakhulu ka-2022. Imboni ye-pasta enkulu kunazo zonke emhlabeni ibonisa amarobhothi ahlanganisiwe nokusabalalisa okuzinzile
