Ibhetri ye-20V yeLithium engenazintambo

Umahluko omkhulu phakathi kwe-lithium drill motor kunye ne-brushless motor ilele kulwakhiwo kunye nokusebenza kwayo:

IMoto ebhurashiweyo: Izixhobo zelithium zemveli zihlala zisebenzisa iimotor ezibrashiweyo. Ezi njini zineebhrashi zekhabhoni ezihambisa amandla kwi-commutator, ethi yona ijikelezise i-aratures yemoto. Njengoko i-motor spins, iibrashi zidibanisa umzimba kunye nomhambisi, ukudala ukukhuhla kunye nokuvelisa ubushushu. Oku kungqubana kunye nokunxiba kwiibhrashi kunye ne-commutator kunokukhokelela ekunciphiseni ukusebenza kakuhle kunye nobomi ngokuhamba kwexesha.

I-Brushless Motor: Ngakolunye uhlangothi, ii-motor ezingenazintambo azisebenzisi iibrashi okanye i-commutator yokunikezelwa kwamandla. Endaweni yoko, baxhomekeke kubalawuli be-elektroniki ukulawula ngokuchanekileyo ukuhamba kombane ukuya kwiimotor windings. Olu luyilo luphelisa imfuno yeebrashi, ukunciphisa ukukhuhlana kunye nokugqoka. Ngenxa yoko, iimoto ezingenabrashi zihlala zisebenza kakuhle, ixesha elide lokuphila, kwaye zithule xa zithelekiswa neemoto ezibrashwayo. Bakwathanda ukuhambisa amandla angakumbi kubukhulu obufanayo kunye nobunzima, bebenza ukuba badume ngakumbi kwizixhobo zamandla ezinje ngo-drill.

Isishwankathelo, ngelixa zombini ezi ntlobo zeenjini zinokunika amandla i-lithium drill, ii-motorless brushless motors zibonelela ngenzuzo ekusebenzeni kakuhle, ubomi, kunye nokusebenza. Nangona kunjalo, banokuza ngexabiso eliphezulu lokuqala xa kuthelekiswa no-drill ngeenjini ezibrashiweyo.

I-lithium drill brush motor ibhekisa kuhlobo lwemoto esetyenziswa kwizixhobo zamandla ezinje ngobhobho kunye nokuncamatheliswa kwebrashi. I-Lithium ibhekisa kuhlobo lwebhetri enika amandla u-drill, ngelixa i-motor ngokwayo inokuba yi-brush okanye i-brushless DC motor.

Iimoto ezixutyiweyo zineebhrashi zekhabhoni ezihambisa umbane ngoku kwi-armature ejikelezayo, ngelixa ii-motor brushless zisebenzisa abalawuli be-elektroniki ukuhambisa amandla kwii-windings. Iimotor ezi-brushless zidla ngokusebenza ngakumbi kwaye zomelele kuneenjini ezibrashwayo, kodwa zikwadla ngokubiza kakhulu.

Iibhetri zeLithium-ion ziqhele ukusetyenziswa kwizixhobo zamandla ngenxa yokuxinana kwamandla aphezulu kunye nendalo ephinda itshajwe, ibonelela ngamaxesha okuqhuba ixesha elide xa kuthelekiswa nezinye iindidi zebhetri. Xa idityaniswe ne-brushless motor, i-lithium-ion-powered drills inokunika ukusebenza okuphezulu kunye nobomi obude besixhobo.
