Yintoni na le amp amandla

Ngowe-1820, yamachiza baziincamisa French Andre Marie Ampere (oko imbeko lakhe igama yokukala of current yombane) iye yaqulunqa omnye imithetho angundoqo abo bonke zobunjineli bombane. Emva koko, lo mthetho it got igama amp amandla.

Njengoko yaziwa, ngexesha indlela umbane ngokusebenzisa umqhubi kwenzeka esijikeleze (eziziisekondari) imigca nemagnethi intsimi ngobunzulu ezenza uhlobo yeqokobhe olujikelezayo. Kwicala le migca yoqheliso magnetic kumiselwa ngokusebenzisa umthetho ngesandla sokunene (lesibini igama "ulawulo ekunene-isandla"): ngengqondo ngesandla sokunene amagwegwe umqhubi ukuze ngenxa amasuntswana ebizwayo ingqamana cala ekhonjwe nasesithupheni bent. Ngenxa yoko, omnye ezine iminwe, yokukhwabusha ucingo, indawo ukuya ukujikeleza endle.

Ukuba ubeka ezi kwezinikezeli ezimbini ngaxeshanye (ucingo obhityileyo), ngoko impefumlelwano amasimi abo otsalayo kuya kuchaphazela amp amandla. Kuxhomekeka ulwalathiso zangoku kwi umqhubi ngamnye, ukuba nomdla okanye aqale. Xa imisinga aqukuqela kwicala elinye, lo amp amandla phezu kwabo ekutsaleni umdla inyathelo. Ngako oko, imisinga kwicala elahlukileyo ebangela isizathu. Oku akumangalisi, lo gama ezifana izityholo dudula, kulo mzekelo, basebenzisane hayi iintlawulo kunye namasimi ngemagnethi. Ekubeni kwicala ukujikeleza iyafana, intsimi lokugqibela udibaniso kumda wesangqa, hayi umahluko.

Ngamanye amazwi, lo mhlaba otsalayo wenza izinto ngendlela ethile ukuya kumqhubi, leyo agqithe kumgca uxinzeleko. Power Amp (engenasizathu imilo umqhubi) uzimisele emthethweni ifomula:

DF = B mna L * isono;

apho - I - ixabiso lika zangoku kwi umqhubi; B - yokuqhelaniswa magnetic, ifumaneka apho izinto conductive; L - athathiweyo ukubala ubude umqhubi kunye yangoku (kwaye kule meko Kuthathwa ukuba ubude umqhubi namandla bayathanda zero); alpha (a) - kumda wesangqa engile ephakathi icala intshukumo kwisuntswana ityala kunye imigca endle lwangaphandle. Eliphezulu lulandelayo: xa engile phakathi zithwala yi degrees 90 ke isono = 1 kunye xabiso liphezulu amandla.

Vector icala amp amandla ixhomekeke kwimithetho ngasekhohlo: abeke ngengqondo isandla sakhe sasekhohlo ukwenzela ukuba imigca (zithwala) loMthetho yoqheliso otsalayo asendle lwangaphandle ezibandakanywe ngesandla evulekileyo, yaye eziseleyo iminwe ezine kulungiswa ibonisa indlela apho ukungena nokuphuma zangoku nombhexeshi. Emva koko ke kruthu nasesithupheni kwi-engile degrees 90, bonisa indlela olusebenza ngayo nombhexeshi. Ukuba engile ephakathi kumda wesangqa ye yangoku yombane kunye umgca induction engenasizathu incinane kakhulu, ukuba lula ukusetyenziswa kolawulo entendeni akufuneki ngokwayo ziquka kumda wesangqa yoqheliso, kunye imodyuli.

Isicelo Ampere amabutho wenza kube lula ukwenza Iimoto zombane. Thina sonke beqhela yokuba kwanele flip iswitshi esi sixhobo nendlu yombane nee-injini yayo indlela basha weza ukusebenza. Kwaye malunga neenkqubo ezenzeka ngexesha elinye, akukho iingqondo kakhulu enye. Direction amp amandla licacisa kuphela siseko ukusebenza kwe-injini, kodwa ukufumanisa apho kanye kuya kuthunyelwa torque.

Ngokomzekelo, cinga injini DC: iankile yakhe - isakhelo-isiseko kunye okukhona siya. An imagnethi lwangaphandle lukhutshwe nezibonda ezizodwa. Ekubeni enxebeni coil phezu armature, le setyhula, ngoko kumacala ahlukeneyo ulwalathiso counter layo ngoku kwiziqephu umqhubi. Ngenxa yoko, le ampere amandla intshukumo kumda wesangqa counterclaims. Ekubeni iankile lukhuselekile ukuba iibheringi, isenzo efanayo kwemikhosi zithwala ampere ivelisa torque. Ngokukhula kwexabiso yangoku ukunyuka yangoku namandla. Kungenxa yoko le nto ngoku rated yombane (echazwe kwi kwisiqinisekiso izixhobo zombane) kunye torque ezinxulumene ngqo. Ukwandisa yangoku anqongophele ngenxa iimpawu constructional: sectioned jiko iingcingo, inani amagophe njalo njalo.
