I-Brushless vs Brushed Motors: Yeyiphi efanelekile kwiProjekthi yakho?

Intshayelelo

Iindidi ezimbini eziqhelekileyo zeemoto zeDC ziimotor ezibrashwayo kunye neemotor ezingenayo i-brushless (iinjini ze-BLDC). Njengoko igama lisitsho, iimoto ezibrashwayo zisebenzisa iibhrashi ukuya kwicala, ezivumela injini ukuba ijikeleze. Ngokwahlukileyo, iinjini zeBrushless zithatha indawo yomsebenzi wokutshintsha oomatshini ngolawulo lombane. Zombini ezi ntlobo zisebenza kumgaqo ofanayo, oko kukuthi umtsalane wemagnethi kunye nokurhoxa kwemagnethi phakathi kwekhoyili kunye nemagnethi esisigxina. Nganye ineengenelo zayo kunye nezingeloncedo zayo, ezinokuphembelela ukhetho lwakho ngokusekelwe kwiimfuno ezithile zesicelo sakho. Ukuqonda umahluko phakathi kweenjini ze-DC ezixutyiweyo kunye ne-brushless DC motors kubalulekile ekuvavanyeni ukusebenza kwazo. Isigqibo sokukhetha uhlobo oluthile kunolunye lusekelwe kwiimpawu ezahlukeneyo, kubandakanywa ukusebenza kakuhle, ubude bokuphila kunye neendleko.

Izinto ezibalulekileyo zomahluko phakathi kwe-brushless kunye ne-brushless DC Motor:

#1. Ukusebenza ngcono

Iimotor ezi-brushless zisebenza ngakumbi kuneenjini ezibrashwayo. Baguqula amandla ombane abe ngamandla oomatshini ngokuchaneka okukhulu, ngaloo ndlela behlisa inkcitho yamandla. Ngokungafaniyo neenjini ze-DC ezibrashwayo, ii-motor ezi-brushless azifumani ukukhuhlana okanye ilahleko yamandla ehambelana neebhrashi kunye nabahambi. Oku kuphucula ukusebenza, kwandisa ixesha lokuqhuba, kwaye kunciphisa ukusetyenziswa kwamandla.

Ngokuchaseneyo, iimoto ezixutyiweyo zithathwa njengezingasebenzi kakuhle kunee-brushless DC motors ngenxa yelahleko yamandla eyayanyaniswa nokungqubana kunye nokuhanjiswa kwamandla ngenkqubo yabahambisi.

#2. Isondlo kunye Nobomi obude

Iimotor ezingenazibhrashizineendawo ezimbalwa ezihambayo kunye nokungabikho koqhagamshelo ngoomatshini, okukhokelela kubomi obude kunye nokuncipha kweemfuno zokulondolozwa. Ukungabikho kweebhulashi kuphelisa iingxaki ezinxulumene nokunxiba kwebrashi kunye neminye imiba yokugcina. Ke ngoko, ii-brushless motors zihlala ziyindlela ebiza kakhulu kubasebenzisi.

Ukongezelela, ii-motor brushed zifuna ukugcinwa okungakumbi ngenxa yokunxiba kunye nokukrazula kwiibrashi kunye ne-commutator, enokuthi iholele ekunciphiseni ukusebenza kunye neengxaki zemoto. Ukugcina ukusebenza kakuhle, iibrashi kufuneka zitshintshwe rhoqo.

#3. Ingxolo kunye neVibration

Kwii-motorless brushless motors, i-winding current inokulawulwa, enceda ukunciphisa i-torque pulsations enokubangela ukungcangcazela kunye nengxolo yomatshini. Ke ngoko, iimoto ezingenabrashi zihlala zivelisa ingxolo encinci kunye nokungcangcazela kuneemoto ezibrashwayo. kuba abanazo iibhrashi okanye abahambi. Ukunciphisa ukungcangcazela kunye nengxolo kuphucula ukuthuthuzela komsebenzisi kwaye kunciphisa ukuguga kunye nokukrazula kusetyenziso olwandisiweyo.

Kwibrashi ye-DC motor, iibrashi kunye ne-commutator zisebenza kunye njengendlela yokutshintsha. Xa i-motor isebenza, ezi zitshintshi zihlala zivula kwaye zivala. Le nkqubo ivumela imisinga ephezulu ukuba ihambe nge-inductive rotor windings, ivelise ingxolo encinci yombane ngenxa yokuhamba okukhulu kwangoku.

#4. Iindleko kunye nokuntsonkotha

Iinjini ze-brushless zithande ukuba zibiza kakhulu kwaye zintsonkothile ngenxa yenkqubo yolawulo lombane lokuhamba. Ixabiso eliphezulu leenjini ze-brushless DC xa kuthelekiswaiinjini ze-DC ezibrashiweyoubukhulu becala kungenxa yobuchwepheshe be-elektroniki obuphambili obubandakanyekayo kuyilo lwabo.

#5. Uyilo kunye nokusebenza

Iinjini ze-Brushless ze-DC azikwazi ukuzihambela. Bafuna isekethe yokuqhuba esebenzisa ii-transistors ukulawula ukuqukuqela kwangoku kwiikhoyili zokujija iimoto. Ezi motors zisebenzisa ulawulo lwe-elektroniki kunye ne-Hall effect sensors ukulawula i-current in the windings, kunokuthembela kuqhagamshelwano ngoomatshini.

Iinjini ze-DC ezixutyiweyo zi-self-commutated, nto leyo ethetha ukuba ayifuni isekethe yomqhubi ukuba isebenze. Endaweni yoko, basebenzisa iibhrashi zoomatshini kunye nabahambisi ukulawula i-current in the windings, ngaloo ndlela bedala indawo yamagnetic. Lo mmandla wemagnethi wenza itorque, ebangela ukuba imotor ijike.

#6. Usetyenziso

Njengexabiso leiinjini zokungcangcazelakunye ne-electronics ehambelana nayo iyaqhubeka nokuhla, imfuno yeemoto ezingena-brushless kunye ne-brushed motors iyanda. Iimotor ezingenanto zidume kakhulu kwii-smartwatches, izixhobo zonyango, izixhobo zobuhle, iirobhothi, njl.

Kodwa kusekho iindawo apho iimoto ezibrashwayo zenza ingqiqo ngakumbi. Kukho usetyenziso olukhulu lweemotor ezibrashiweyo kwii-smartphones, i-e-cigarettes, abalawuli bomdlalo wevidiyo, ii-massager zamehlo, njl.
