Kutheni izixhobo zeBrushless zisiba zidume ngakumbi?

Njengoko imfuno yezixhobo zamandla isanda yonke imihla, uninzi lwabavelisi bezixhobo zamandla bagxile ekuveliseni izixhobo zamandla ezineempawu eziphambili ukukhuphisana neempawu ezaziwayo-kakuhle. Izixhobo zamandla ngeibrashiitekhnoloji iya ithandwa kakhulu phakathi kwe-DIYers, iingcali, kunye nabavelisi bezixhobo zamandla ngeenjongo zokuthengisa, engeyiyo intsha.

Xa i-dimmer yamandla ekwaziyo ukuguqula i-alternating current (AC) ukuya ngqo ngoku (DC) yaqanjwa ekuqaleni kweminyaka yoo-1960, izixhobo zamandla ezineenjini zokusebenzisa i-brushless zasasazeka. Ubuchwephesha obusekwe kwimagnethi busetyenziswe kwizixhobo ngabavelisi bezixhobo zamandla; ibhetri yombane emva koko yalungelelanisa ezi zixhobo zamandla zisekwe kwimagnetism. Iinjini ze-Brushless zayilwa ngaphandle kokutshintsha ukuhambisa okwangoku, kwaye uninzi lwabavelisi bezixhobo zamandla bakhetha ukwenza kunye nokuhambisa izixhobo ezineenjini ezingenasibhrashi kuba zithengisa ngcono kunezixhobo ezixutyiweyo.

Izixhobo zamandla ezineenjini ezingasebenziyo azizange zidume de kwangoo-1980. Injini yeBrushless inokuvelisa amandla afanayo njengeemotor ezibrashwayo enkosi kwiimagnethi ezisisigxina kunye neetransistors ezinombane ophezulu. Uphuhliso lweemoto ezingenamabhurashi alukhange lume kule minyaka ingamashumi amathathu idlulileyo. Ngenxa yoko, abavelisi bezixhobo zamandla kunye nabasasazi ngoku babonelela ngezixhobo zamandla ezithembeke ngakumbi. Ngenxa yoko, abathengi bayaxhamla kwiinzuzo eziphambili ezifana neyantlukwano enkulu kunye neendleko eziphantsi zokulondolozwa ngenxa yoku.

IiMoto ezibhurashiweyo kunye neBrushless, zeziphi iiMahluko? Yeyiphi Esetyenziswa Ngakumbi?

IMoto ebhurashiweyo

I-armature yemoto ye-DC ebrashiweyo isebenza njenge-electromagnetic-pole-pole kunye noqwalaselo lweekhoyili zocingo lwenxeba. I-commutator, i-mechanical rotary switch, itshintsha i-directionality yangoku kabini kumjikelo ngamnye. Iipali ze-electromagnetic zityhala kwaye zitsale ngokuchasene nemagnethi ezijikeleze umphandle wenjini, zivumela umsinga ukuba udlule ngokulula kwi-armature. Njengoko iipali zomhambisi zinqumla iipali zemagnethi ezisisigxina, i-polarity ye-electromagnetic ye-armature iyajikwa.

IMoto yeBrushless

Ngakolunye uhlangothi, i-brushless motor inemagnethi esisigxina njenge-rotor yayo. Ikwasebenzisa izigaba ezithathu zokuqhuba iikhoyili kunye neseva ephucukileyo ebeka iliso kwindawo yerotor. Inzwa ithumela imiqondiso yereferensi kumlawuli njengoko ibona i-rotor orientation. Iikhoyili zenziwa zisebenze ngendlela ecwangcisiweyo ngumlawuli, nganye nganye. Kukho ezinye iingenelo kwizixhobo zamandla ngetekhnoloji ye-brushless, ezi zibonelelo zezi zilandelayo:

• Ngenxa yokunqongophala kweebhrashi, kukho iindleko ezipheleleyo zokuzilungisa.
• Itekhnoloji yeBrushless iqhuba kakuhle kuzo zonke izantya ngomthwalo olinganisiweyo.
• Itekhnoloji yeBrushless yonyusa izinga lokusebenza kwesixhobo.
• Itekhnoloji yeBrushless ibonelela isixhobo ngeempawu ezininzi eziphezulu ze-thermal.
• Itekhnoloji yeBrushless yenza ingxolo yombane esezantsi kunye noluhlu lwesantya esikhulu.

Iimotor ezingasebenziyo ngoku zidume kakhulu kuneemotor ezibrashwayo. Zombini, kwelinye icala, zinokusetyenziswa kwiintlobo ngeentlobo zezicelo. Kwizixhobo zasekhaya kunye nezithuthi, iimoto ze-DC ezibrashwayo nazo zisetyenziswa ngokubanzi. Basenayo imarike yorhwebo eyomeleleyo ngenxa yokukwazi ukutshintsha i-torque-to-speed ratio, efumaneka kuphela ngeenjini ezixutywe.

Yonwabela iTekhnoloji yeBrushless ngothotho lweziXhobo zaMandla

I-Tiankon isebenzise ii-motor ezingena-brush kuluhlu lwamva nje lwe-20V yezixhobo ezomeleleyo, njengezinye iibrendi ezaziwayo ezifana ne-Metabo, i-Dewalt, i-Bosch, kunye nezinye. Ukunika abasebenzisi uvuyo lokusebenzisa izixhobo zamandla ezingenabrushless, iTiankon, njengomvelisi wezixhobo zamandla, ikhuphe umgca wegrinder ye-angle encinci ye-brushless, i-die grinders, i-effect drills, i-screwdrivers, ii-wrenches zempembelelo, iihamile ezijikelezayo, ii-blowers, i-hedge trimmers, kunye izilungisi zengca, zonke ezisebenza ngebhetri enye. Khawube nomfanekiso-ngqondweni wakho ukwazi ukwenza nantoni na ngebhetri enye: isarha, ukugrumba, ukucheba, ukupolisha, njalo njalo. Njengomphumo wokuba neebhetri ezintsha ezihambelanayo, akuyi kuphucula ukusebenza kuphela, kodwa ixesha kunye nendawo ziya kugcinwa. Ngenxa yoko, unokuhlawulisa izixhobo zakho kube kanye kwaye ufezekise amakhulu emisebenzi ngebhetri enye esebenza nazo zonke izixhobo zakho.

Olu chungechunge lwesixhobo se-brushless luza neebhetri ezimbini ezinamandla: ibhetri ye-20V yebhetri ene-2.0AH ye-Li-ion ibhetri kunye ne-20V ibhetri yebhetri ene-4.0AH Li-ion ibhetri. Ukuba ufuna ukusebenza ixesha elongeziweyo, i-20V 4.0Ah ibhetri ipakethe yeyona ndlela ilungileyo kuba inika amandla izixhobo ixesha elide. Ngaphandle koko, ipakethe yebhetri ye-20V enebhetri ye-2.0Ah Li-ion lukhetho oluhlakaniphileyo ukuba ukujongana nezixhobo akuthathi ixesha elide.
