Ukuqala zamanje

Lapho kufakwe nokuqhutshwa apharathasi, indlela noma idivayisi isikhathi isikhathi lapho kukhona izinqubo, ababiziweyo non-umile noma iziqhumane. Izibonelo edume kakhulu ekuphileni - ukuba aqhele, ake sithi, ukushayela iloli elithwele, isitimela, bha lokho kuyinkomba yokuthi leyompahla kokuqala amandla umfutho ngokuvamile kudingeka ezingaphezu kuka umzamo esikhathini esizayo.

Ngezindawo asho into eyodwa zenzeka kumadivayisi kagesi: izibani, izinjini, electromagnets, njll Ukuqala izinqubo kulezi kumadivayisi kuncike isimo umsebenzi izinto: izibani intambo, isimo magnetization we core Yikhoyili electromagnet, degree of ionization igebe interelectrode e osenyameni izibani igesi , njll Ngokwesibonelo, cabanga intambo ye isibani. Kuyaziwa ukuthi isimo abandayo, it has a ukumelana ephansi kakhulu kunalokho uma
lishise amadigri 1000. e imodi esebenzayo. Zama ukubala ukumelana
intambo ngoba isibani 100-watt - mayelana 490 ohms, futhi ohmmeter kulinganiswa esimweni sokungenzi lutho wokuthi imfushane kunalokho ohms 50. Futhi manje ezithakazelisa kakhulu - ukubala wamanje inrush, futhi uzoqonda ukuthi kungani ama basuke ovuthayo lapho luvulwe.

It kuvela ukuthi ngesikhathi samanje ivuliwe sifinyelela 4-5, okuyinto amandla ukusetshenziswa ezingaphezu kuka 1 kW. Pho kungani 100-watt amalambu ungayishisi, "ngaphandle kokukhetha"? Yebo ngoba, Ukushisa, isibani intambo has
Ukumelana okwandisa, okuyinto esimweni engaguquki kuba njalo, lenani elikhulu kokuqala, kuletse yokusebenza yamanje azungeze 0.5 A.

motors kagesi abe isicelo ebanzi ubuciko, ngakho ulwazi izici starting yabo izici Kubalulekile efanele ukusebenza eletroprivodov. Slip ne torque ku kushaft - main ezithinta ukuqala izilungiselelo zamanje. Okokuqala sibopha emkhakheni kagesi ngsivinini Ukujikeleza nesivinini Rotor nge speed isethi incipha kusuka 1 kuya inani eliphansi, kanti eyesibili inquma umthwalo mechanical ku shaft, esiphezulu ekuqaleni ukuqala futhi emva ukusheshisa full okuzisholo. motor Okungavumelanisiwe ngesikhathi kuyiwe transformer okulingana sesiwancamulile yesibili emazombezombe. Ngenxa encane yayo
Ukumelana kokuqala samanje motor evele ifinyelela ngokweqile ngokuphindwe kayishumi ukubaluleka kwalo esinesilinganiso.

ukuthengisela yamanje Windings Rotor kuphumela saturation ukwanda core e kazibuthe, ukubukeka i EMF self-inductance, okuholela ukwanda exhasa
Ukumelana wesifunda. Rotor iqala ukujikisa, kanye isilinganiso ukushelela incipha, ngamanye amazwi, It ngesivinini injini. Kulokhu wamanje eziqala nezibhelu ezaseziqubuka Sehlile value izinze.

Izinkinga kubangelwa okuvela anda inrush imisinga kuphakama
ngenxa okweqile izinjini kagesi, sindisa amanethiwekhi kagesi okwamanje
qala-up, okuvela mechanical ukushaqeka imithwalo enamathiselwe indlela ezifana amagiya. Kunezinhlobo ezimbili amakilasi lamadivayisi ukuxazulula le mibuzo kwezobuchwepheshe banamuhla - temusho esithambile futhi imvamisa converters.

Ukukhetha kwabo - kungcono inkinga ubunjiniyela ne ukuhlaziywa eziningi tekusebenta
izici. Umthwalo ezimweni zangempela ukusetshenziswa kwama-motor kagesi ngamaqembu amabili: futha-fan jikelele. temusho Soft kuthiwa okungcono esetshenziselwa imithwalo fan iyunithi. nabalawuli okunjalo kukhawulwe zamanje inrush ezingeni akazidluli 2 amagugu okuzisholo, esikhundleni 5-10 izikhathi ezijwayelekile ekuqaleni-up, ngokushintsha Windings voltage.

Inqubo esetshenziswa kabanzi embonini kukhona motors kagesi kushintshana zamanje. Nokho, design yabo elula futhi eziphansi kuyinto kolunye uhlangothi - izimo sokuqala esindayo ukuthi zinciphe esebenzisa imvamisa converters. Isici esibalulekile kakhulu imvamisa
transducer ukwesekwa inrush zamanje lokungeniswa motor ngoba
isikhathi eside - iminithi noma ngaphezulu. Izibonelo best of converters zanamuhla amadivaysi ezihlakaniphile ezisebenza nje uqale ukulawula inqubo, kodwa futhi nokwandisa kokuqala iyiphi criteria ukusebenza enikeziwe: yobukhulu nokusakazeka aphikelele kokuqala zamanje, elislayidayo kushaft torque, elikhulu amandla isici, njll
