Wahi a kamea hana kaʻa uila, ke kumu hana o kakaʻa dcʻo ia ka hoʻololi ʻana i ka ikaika electromotive ʻē aʻe i hana ʻia e ka hoʻokomo ʻana i ka coil armature i kahi ikaika electromotive o kēia manawa ke huki ʻia mai ka hopena o ka palahū e ka commutator a me ka hana commutator o ka pulupulu.
Mai ka hana commutator e wehewehe: ʻaʻole e hoʻohui ka pulupulu i ka uila dc, me ka mea hoʻoneʻe mua e kauo i ka armature counterclockwise ka hoʻololi mau ʻana i ka wikiwiki, ʻo nā ʻaoʻao ʻelua o ka coil i ʻoki i ka laina ikaika ma lalo o ka polarity ʻokoʻa o ka pou magnetic, a i loko. ka mea i hoʻoulu ʻia e ka induction i ka ikaika electromotive, ke kuhikuhi ikaika electromotive e like me ke kānāwai lima ʻākau e hoʻoholo ai.
Ma muli o ka holo mau ʻana o ka armature, pono e hoʻokau ʻia ka mea lawe i kēia manawa i nā ʻaoʻao coil ab a me CD i loko o kahi māla magnetic e ʻoki ʻoki i nā laina o ka ikaika ma lalo o nā pole N a me S, ʻoiai ke kuhikuhi o ka ikaika electromotive i hoʻokomo ʻia. ma kēlā me kēia ʻaoʻao wili a puni ka ʻōwili e ʻāwili ana.
ʻO ka ikaika electromotive i hoʻokomo ʻia i loko o ka coil he ikaika electromotive ʻokoʻa, aʻo ka ikaika electromotive ma ka hope o ka pulupulu A a me B he ikaika electromotive pololei.
No ka mea, i ke kaʻina o ka hoʻololi ʻana i ka armature, ʻaʻohe mea i kahi e huli ai ka armature, no ka hana commutator a me ka brush commutator, ʻo ka ikaika electromotive i hoʻokomo ʻia e ka pulupulu A ma o ka commutator blade, ʻo ia ka ikaika electromotive ma ka lihi o ka coil e ʻoki ana i ka n. -lālani kahua mākia pole. No laila, he polarity maika'i ko ka puluki A.
Ma keʻano like, he polarity maikaʻiʻole ka'ōpala B, no laila hiki i ka hopena o ka pulupulu ke alakaʻi i ka mana electromotive pulse o ke kuhikuhi mau akā keʻano likeʻole. hiki ke loaʻa ka ikaika electromotive dc.
ʻO kēia ke ʻano o ka hana ʻana o nā motika dc. Ua hōʻike pū ʻia ʻo ka sub - dc motor he mea hana ac me ka commutator.
Wahi a ka hoʻolauna ʻana o nā mea hana kaʻa vibration, mai ke kūlana electromagnetic maʻamau, hiki i kahi motika dc ma ke kumu ke hana ma ke ʻano he kaʻa holo, hiki ke holo ʻia ma ke ʻano he generator, akā ʻokoʻa nā mea paʻa.
Ma nā wēlau ʻelua o ka mīkini dc, hoʻohui i ka uila dc, hoʻokomo i ka ikehu uila i loko o ka armature, hoʻopuka ʻia ka ikehu mechanical mai ke kumu kaʻa, ka mīkini hana huki, ka ikehu uila i ka ikehu mechanical a lilo i kaʻa;
Inā hoʻohana ʻia ka prime mover e kauo i ka armature o ka motor dc, a ʻaʻole i hoʻohui ka pulupulu i ka uila dc, a laila hiki i ka hopena o ka pulupulu ke alakaʻi i ka ikaika electromotive dc ma ke ʻano he kumu mana dc, hiki ke hoʻopuka i ka ikehu uila. Hoʻololi ke kaʻa i ka ikehu mechanical i ka ikehu uila a lilo i ka moto generator.
ʻO ke kumu e hiki ai i ka motika like ke hana ma ke ʻano he kaʻa uila a i ʻole he generator.
