Uyilo lwe-4-pole yomelele ngakumbi kune-2-pole elinganayo, kodwa inokuthatha indawo efanayo kunye nobunzima.UGreg Dutfield ovela ku-maxon UK uyachaza.
Iimowutha ezineepali ezi-4 zineengenelo ekukhetheni iinjini ze-DC ezincinci zezicelo ukusuka kwi-aerospace ukuya kulawulo lokugrumba kakuhle.Uyilo lwe-4-pole yomelele ngakumbi kune-2-pole elinganayo, kodwa inokuthatha indawo efanayo kunye nobunzima.UGreg Dutfield ovela ku-maxon UK uyachaza.
Kwiimoto ze-DC ezifuna i-torque ephezulu enobunzima obuphantsi kunye nokuqina, i-motor ye-4-pole inokuba lolona khetho lungcono.Iimotor ezineepali ezi-4 zinokuthatha unyawo olufanayo njengee-motor ezi-2, kodwa ziyakwazi ukuvelisa i-torque eyongezelelekileyo.Kubalulekile ukuba uqaphele ukuba i-motor ye-4-pole yomelele ngakumbi kune-2-pole motor yobukhulu obulinganayo, oku kuthetha ukuba igcina isantya sayo ngokuchanekileyo xa kufakwe umthwalo.
Inani leepali libhekiselele kwinani leeperi zemagnethi ezisisigxina kwinjini.Injini enepoleni ezimbini ineemagnethi ezijonge emantla nasezantsi.Xa i-current isetyenziswe phakathi kweebini zezibonda, intsimi yamagnetic yenziwe, ibangela ukuba i-rotor ijikeleze.Ulungelelwaniso lweemoto lukwahluka ukusuka kwi-4-pole, kubandakanywa izibini ezimbini zeepali, ukuya kwi-multi-pole designs, kubandakanywa ukuya kwiipali ze-12.
Inani leepali liyinkalo ebalulekileyo yoyilo lweemoto njengoko luchaphazela isantya kunye neempawu ze-torque zemoto.Okukhona lisezantsi inani leepali, kokukhona siphezulu isantya senjini.Oku kungenxa yokuba ukujikelezwa komatshini ngamnye we-rotor kuxhomekeke ekugqityweni komjikelo wemagnethi kwipere nganye yezibonda.Okukhona izibini ezininzi zeemagnethi ezisisigxina injini inazo, kokukhona imijikelo yovuselelo iyafuneka, nto leyo ethetha ukuba ithatha ixesha elide i-rotor ukugqiba ukujikeleza kwe-360 °.Isantya sahlulahlulwe ngenani leepali zeepali kwi-frequency esisigxina, ngoko kucingwa ukuba i-2-pole motor kwi-10,000 rpm, i-motor ye-4-pole iya kuvelisa i-5000 rpm, i-motor-pole motor iya kugijima kwi-3300 rpm, njl. ..
Iinjini ezinkulu ziyakwazi ukuvelisa i-torque eninzi kungakhathaliseki inani leepali.Nangona kunjalo, ukwandisa inani leepali kunokuvelisa i-torque eninzi kunemoto yobukhulu obufanayo.Kwimeko ye-4-pole motor, i-torque yayo yonyuka kakhulu ngoyilo lwayo oluhlangeneyo kunye nendlela yokubuyisela imagnethi encinci eshiya indawo eninzi yeepali ezimbini zemagnethi ezisisigxina, kwaye kwimeko yeemotor ze-maxon, i-patent yayo ene-patent ejiyileyo ephothiweyo yokujika.
Nangona i-4-pole motor inokuthatha indawo efanayo yoyilo lweepali ezi-2, kufuneka kuqatshelwe ukuba ukwanda okungaphezulu kwenani leepali ukusuka kwi-6 ukuya kwi-12 kuthetha ukuba ubukhulu kunye nobunzima befreyimu kufuneka bunyuswe ngokulinganayo vumela intambo yobhedu eyongezelelweyo., intsimbi kunye neemagnethi azifunwa.
Amandla emoto adla ngokumiselwa sisantya se-torque gradient, nto leyo ethetha ukuba imotor enamandla ngakumbi inokubamba isantya siqine ngakumbi xa kufakwa umthwalo.I-speed-torque gradient ilinganiswa ngokuhla kwesantya kwi-1 mNm yomthwalo.Amanani asezantsi kunye namabakala amancinci athetha ukuba injini iya kukwazi ngcono ukugcina isantya sayo phantsi komthwalo.
Imoto enamandla ngakumbi inokwenzeka ngenxa yeempawu zoyilo ezifanayo ezikwanceda ukuba ifezekise iitorque eziphezulu, ezinje ngee-windings ezingaphezulu kunye nokusetyenziswa kwezixhobo ezifanelekileyo kwinkqubo yokwenziwa.Ngaloo ndlela i-4-pole motor inokuthenjwa ngakumbi kune-2-pole motor yobukhulu obufanayo.
Umzekelo, i-4-pole maxon motor enobubanzi obuyi-22 mm inesantya kunye ne-torque gradient ye-19.4 rpm/mNm, oku kuthetha ukuba ilahlekelwa kuphela yi-19.4 rpm kwi-1 mNm nganye esetyenziswayo, ngelixa i-2-a maxon pole motor ye- ubungakanani obufanayo bunesantya kunye nethambeka letorque ye-110 rpm./mNm .Ayingabo bonke abavelisi beemoto abahlangabezana noyilo lwe-maxon kunye neemfuno zemathiriyeli, ngoko ke ezinye iibrand zeemoto ezi-2-pole zinokuba nesantya esiphezulu kunye ne-torque gradients, ebonisa imotor ebuthathaka.
Usetyenziso lwe-aerospace luzuza kumandla akhulayo kunye nobunzima obulula bee-motor ezi-4.Ezi mpawu zikwafuneka kwizixhobo zamandla ezibanjwa ngesandla, ezihlala zifuna i-torque engaphezulu kune-2-pole motor inokubonelela, kodwa zilula ngobunzima kwaye zincinci ngobukhulu.
Ukusebenza kwemoto ye-4-pole kubalulekile kubenzi beerobhothi ezihambayo.Iirobhothi ezinamavili okanye ezilandelelweyo kufuneka zoyise umhlaba omagingxigingxi, imiqobo kunye namathambeka amaqhina xa zihlola imibhobho yeoli nerhasi okanye zikhangela amaxhoba enyikima.Iinjini ze-4-pole zibonelela ngetorque kunye namandla afunekayo ukoyisa le mithwalo, inceda abavelisi berobhothi abahambahambayo ukuba bakhe i-compact kunye noyilo olukhaphukhaphu.
Ubungakanani obuncinci, zidibaniswe nesantya esisezantsi kunye ne-torque gradients, bukwabalulekile ekulawuleni kakuhle kwishishini leoli kunye negesi.Kwesi sicelo, iimoto ezineepali ezi-2 azinamandla ngokwaneleyo kwaye iimotor ezineepali ezininzi zikhulu kakhulu kwindawo yokuhlola kancinane, ke uMaxon waphuhlisa i-32mm ye-4-pole motor.
Izicelo ezininzi ezifanelekileyo kwi-4-pole motors zenzeka kwiindawo ezigqithiseleyo okanye kwiimeko ezifuna ukukwazi ukusebenza kwiqondo lokushisa eliphezulu, uxinzelelo oluphezulu kunye nokungcangcazela.Ngokomzekelo, iimoto zokulawula kakuhle zingasebenza kumaqondo okushisa angaphezu kwe-200 ° C, ngelixa ii-motor ezifakwe kwi-autonomous underwater vehicles (AUVs) zigcinwe kwiitanki ezizaliswe ngeoli.Ngeempawu ezongezelelweyo zoyilo ezifana nemikhono kunye nobuchwepheshe bokuphucula ukuchithwa kobushushu, ii-compact 4-pole motors ziyakwazi ukumelana neemeko zokusebenza ezigqithisileyo ixesha elide.
Ngelixa iinkcukacha zemoto zibalulekile, uyilo lwenkqubo yonke yokuqhuba, kubandakanya ibhokisi yegiya, i-encoder, ukuqhuba kunye nolawulo, kufuneka kuthathelwe ingqalelo ukwenza usetyenziso lube lukhulu.Ukongeza ekuboniseni iinkcukacha zeemoto, iinjineli ze-maxon zinokusebenza kunye namaqela ophuhliso lwe-OEM ukuphuhlisa iinkqubo ezichanekileyo zokuqhuba ezichanekileyo.
I-maxon ngumthengisi ohamba phambili wokuchaneka okuphezulu kwebrashi kunye ne-brushless DC servo motors kunye nedrive.Ezi motors ziqala ngobukhulu ukusuka kwi-4mm ukuya kwi-90mm kwaye zifumaneka ukuya kuthi ga kwi-500W.Sidibanisa iimoto, iigiya kunye nolawulo lweemoto ze-DC kwiinkqubo ezichanekileyo zokuqhuba ezikrelekrele ezinokuthi zilungiselelwe ukuhlangabezana neemfuno ezithile zezicelo zabathengi bethu.
Awona manqaku angcono ka-2022. Owona mveliso mkhulu wepasta wehlabathi ubonisa iirobhothi ezidityanisiweyo kunye nokuhanjiswa okuzinzileyo.
