polyphase coil

polyphase coil vidyut chumbakiya coil hotey hain joe ack polyphase pranali jaise generator yaa motor mein ack saath judey hotey hain. aadhunik pranaliyon mein, charanon kii sankhya aamtaur parr teen yaa teen kii ack gunaa hoti haye. pratyek charan mein ack signsoidal vaikalpik dhaara hoti haye jiska charan apane padosiyon mein seey ack key saapeksh vilambit hotaa haye aur apane dusare padosi key saapeksh unnat hotaa haye. charan dhaaraon koo baari-baari seey pravaah kii pratyek avadhi key bheetar samaan roop seey alag kiya jaataa haye. udaaharan key liye, teen-charan pranali mein, charanon koo ack-dusare seey avadhi key ack tihai seey alag kiya jaataa haye.
kundal nirmaan.
vidyut machinary mein upayog kii jaane vaali sabhi kundaliyon kii tarah, polyphase kundaliyan (insulated conducting wire seey bunny) radial anumaanon aur chumbakiya kshetra key liye adhikatam core-satah key sampark key saath lauh chumbakiya armature key aspas ghaav hoti hain.
windings bhautik roop seey ack vidyut machine kii paridhi key aspas alag kiye jaate hain. iss tarah kii vyavastha kaa parinam ack ghoornan chumbakiya kshetra haye jiska upayog vidyut shakti koo ghoornan yaantrik kaary mein badalane key liye kiya jaataa haye, yaa isake vipareet.
polyphase motor aur generator.
ekal-charan motors aur generators kii tulanaa mein, polyphase motor saral hain, kyonki unhein praarambhik tork kaa utpaadan karane key liye baahari paripath (sandharitron aur prerakon kaa upayog karke) kii aavashyakta naheen hoti haye. polyphase masheenen vaikalpik dhaara kii pratyek avadhi mein nirantar shakti pradaan curr sakati hain, ack ekal-charan machine mein paae jaane vaale spandanon koo samaapt karati hain kyonki dhaara shoonya ayam seey gujarati haye.
itihas.
vidyut oorjaa pranaliyon mein polyphase coil key upayog kaa beedaa engineer nikola tesla, galileo ferraris aur michael dolivo-dobrovolsky ney uthaaya thaa.
