Kungani Amathuluzi E-Brushless Eqala Ukuduma Kakhulu?

Njengoba isidingo samathuluzi kagesi sikhula nsuku zonke, abakhiqizi abaningi bamathuluzi amandla bagxila ekukhiqizeni amathuluzi amandla anezici ezithuthukisiwe ukuze baqhudelane nemikhiqizo eyaziwayo. Amathuluzi amandla ngei-brushlessubuchwepheshe buya buduma kakhulu phakathi kwama-DIYers, ochwepheshe, nabakhiqizi bamathuluzi amandla ngezinjongo zokumaketha, okungekusha.

Lapho i-dimmer yamandla enekhono lokuguqula i-alternating current (AC) iye ku-direct current (DC) isungulwa ekuqaleni kwawo-1960, amathuluzi kagesi anamamotho ama-brushless asakazeka kabanzi. Ubuchwepheshe obusekelwe ku-Magnetism busetshenziswe kumathuluzi abakhiqizi bamathuluzi amandla; ibhethri likagesi libe selilinganisa la mathuluzi amandla asekelwe kukazibuthe. Amamotho e-brushless aklanywe ngaphandle kweswishi ukuze adlulise amanje, futhi iningi labakhiqizi bamathuluzi amandla bancamela ukukhiqiza nokusabalalisa amathuluzi anama-brushless motors ngoba athengisa kangcono kunamathuluzi abhulashiwe.

Amathuluzi kagesi anama-brushless motors awazange adume kuze kube ngawo-1980. I-Brushless motor ingakhiqiza inani lamandla afanayo namamotho amabhulashi ngenxa yozibuthe abangashintshi kanye nama-transistors anamandla amakhulu. Ukuthuthukiswa kwezimoto ezingenabhulashi akumile kule minyaka engamashumi amathathu edlule. Ngenxa yalokho, abakhiqizi nabasabalalisi bamathuluzi kagesi manje sebehlinzeka ngamathuluzi kagesi athembeke kakhulu. Ngenxa yalokho, amakhasimende azuza ezinhlelweni ezibalulekile njengokuhlukahluka okukhulu kanye nezindleko zokulungisa eziphansi ngenxa yalokhu.

Ama-brushless Motors nama-Brushless Motors, Uyini Umehluko? Yikuphi Okusetshenziswa Kakhulu?

I-Brushed Motor

I-armature ye-DC motor ebhulashiwe isebenza njengozibuthe wezigxobo ezimbili ngokucushwa kwamakhoyili ezintambo zesilonda. I-commutator, i-rotary switch, ishintsha indlela yamanje kabili ngomjikelezo ngamunye. Izigxobo zikazibuthe kagesi ziphusha futhi zidonse kumagibuthe azungeze ngaphandle kwenjini, okuvumela amandla akhona ukuthi adlule kalula ku-armature. Njengoba izigxobo zomshayeli ziwela izigxobo zikazibuthe ezihlala njalo, i-polarity kazibuthe we-armature iyahlehla.

I-Brushless Motor

I-brushless motor, ngakolunye uhlangothi, inozibuthe ongunaphakade njenge-rotor yayo. Iphinde isebenzise izigaba ezintathu zamakhoyili okushayela kanye nenzwa eyindida eqapha ukuma kwe-rotor. Inzwa ithumela amasignali ereferensi kusilawuli njengoba ithola umumo we-rotor. Amakhoyili abe esesebenza ngendlela ehlelekile ngumlawuli, ngamunye ngamunye. Kunezinzuzo ezithile zokusebenzisa amathuluzi amandla ngobuchwepheshe be-brushless, lezi zinzuzo zimi kanje:

• Ngenxa yokuntuleka kwamabhulashi, kunezindleko eziphelele zokulungisa.
• Ubuchwepheshe be-Brushless busebenza kahle kuzo zonke izivinini ngomthwalo olinganiselwe.
• Ubuchwepheshe obungenabhurashi bukhuphula izinga lokusebenza kwethuluzi.
• Ubuchwepheshe be-Brushless bunikeza idivayisi ngezici eziningi ezishisayo ezishisayo.
• Ubuchwepheshe be-Brushless budala umsindo ophansi kagesi kanye nebanga lesivinini esikhulu.

Amamotho angenabhulashi manje asedume kakhulu kunama-brushed motors. Kokubili, ngakolunye uhlangothi, kungasetshenziswa ezinhlobonhlobo zezinhlelo zokusebenza. Ezintweni zikagesi zasendlini nasezimotweni, ama-DC motors axutshwe nawo asetshenziswa kabanzi. Basenemakethe eqinile yezohwebo ngenxa yekhono lokushintsha isilinganiso se-torque-to-speed, esitholakala kuphela ngama-motor brushed.

Jabulela Ubuchwepheshe Be-Brushless Ngochungechunge Lwamathuluzi Amandla

I-Tiankon isebenzise amamotho e-brushless ohlwini lwayo lwakamuva lwamathuluzi ahlala isikhathi eside we-20V, njengamanye amabhrendi aziwayo njenge-Metabo, i-Dewalt, i-Bosch, nezinye. Ukuze unikeze abasebenzisi injabulo yokusebenzisa amathuluzi wamandla angenasici, i-Tiankon, njengomkhiqizi wamathuluzi kagesi, ikhiphe ulayini we-brushless mini angle grinders, ama-die grinder, ama- impact drill, ama-screwdriver, ama- impact wrennch, izando ezijikelezayo, ama-blower, izinqamuli ze-hedge, kanye izinqamuli zotshani, zonke ezisebenza ngebhethri elilodwa. Cabanga nje ukwazi ukwenza noma yini ngebhethri elilodwa: ukusaha, ukubhoboza, ukusika, ukupholisha, nokunye. Njengomphumela wokuba namabhethri amasha ahambisanayo, ukusebenza ngeke kuthuthukiswe kuphela, kodwa nesikhathi nendawo kuzolondolozwa. Ngenxa yalokho, ungashaja amathuluzi akho kanye futhi ufeze amakhulukhulu emisebenzi ngebhethri elilodwa elisebenza nawo wonke amathuluzi akho.

Lolu chungechunge lwamathuluzi e-brushless lufika namabhethri amabili anamandla: ibhethri engu-20V enebhethri engu-2.0AH Li-ion kanye nebhethri engu-20V enebhethri engu-4.0AH Li-ion. Uma udinga ukusebenza isikhathi eside, iphakethe lebhethri le-20V 4.0Ah liyindlela engcono kakhulu ngoba linika amandla amathuluzi isikhathi eside. Uma kungenjalo, iphakethe lebhethri elingu-20V elinebhethri engu-2.0Ah Li-ion liyisinqumo esihlakaniphile uma ukusebenza ngamathuluzi kungathathi isikhathi eside.
