Iimpawu ezisebenzayo zeebrashi zekhabhoni

Iimpawu zokusebenza zeiibrashi zekhabhoni

Umsebenzi we-carbon brush ngokuyinhloko kukuqhuba umbane ngelixa uxubha kwintsimbi. Ayifani naxa intsimbi ikhuhla kwaye ihambisa umbane kwintsimbi; Iibrashi zekhabhoni azikwenzi kuba ikhabhoni nentsimbi zizinto ezimbini ezahlukeneyo. Uninzi lokusetyenziswa kwayo lusetyenziswa kwiimotor, kwaye iimilo ziyahlukahlukana, isikwere kunye nokujikeleza, njalo njalo.

Iibrashi zekhabhonizilungele zonke iintlobo zeenjini, iijenereyitha, kunye noomatshini beasi. Inomsebenzi omhle wokubuyisela umva kunye nobomi benkonzo ende. Ibrashi yekhabhoni isetyenziswa kwi-commutator okanye i-slip ring ye-motor. Njengomzimba woqhagamshelwano otyibilikayo okhokelela kwaye ungenisa ngoku, unokuqhuba kakuhle kombane, ukuhanjiswa kwe-thermal kunye nokusebenza kwe-lubricating, kwaye unamandla athile omatshini kunye nethuku leentlantsi zokutshintsha. Phantse zonke iimotor zisebenzisa iibrashi zekhabhoni, eziyinxalenye ebalulekileyo yemoto. Isetyenziswa kakhulu kwiijeneretha ezahlukeneyo ze-AC kunye ne-DC, ii-motor synchronous, ii-motor ze-DC zebhetri, amakhonkco omqokeleli we-crane motor, iintlobo ezahlukeneyo zoomatshini bokuwelda njalo njalo. Ngophuhliso lwesayensi kunye nethekhnoloji, iintlobo zeenjini kunye neemeko zokusebenza zokusetyenziswa ziya zihluka ngakumbi

Indima ethile yeiibrashi zekhabhoni

1. Yongeza i-current current (i-excitation current) kwi-rotor ejikelezayo (i-input current) nge-carbon brush;

2. Yazisa umrhumo we-static kwi-shaft enkulu emhlabeni (i-carbon brushed brushed) nge-carbon brush (imveliso yangoku);

3. Khokela i-shaft enkulu (umhlaba) kwisixhobo sokukhusela sokukhusela umhlaba we-rotor kunye nokulinganisa i-voltage yomhlaba echanekileyo kunye nembi ye-rotor;

4. Guqula isalathiso sangoku (kwi-motor commutator, ibrashi nayo idlala indima yokutshintsha)

Ngaphandle kwe-induction ye-AC motors asynchronous. Kukho ezinye ii-motor, nje ukuba i-rotor ine-ring commutation.

Umgaqo wokuvelisa amandla kukuba emva kokuba intsimi yamagnetic inqumle ucingo, i-current iveliswa kwi-wire. Ijenereyitha inqumla ucingo ngokujikelezisa umhlaba wemagnethi. Intsimi yamagnetic ejikelezayo yi-rotor, kwaye iingcingo ezisikiweyo ziyi-stator.
