Kodi alternating panopa?

Za mitundu ya magetsi onse kulankhula ngakhale maphunziro sayansi kusukulu. Kwa ena, amenewa ndi ongolankhula chidziwitso, kulimbikitsa kumvetsa kuti dziko, pamene ena kusankha zapaderazi, mwachindunji zokhudzana ndi mphamvu. Kaya izi, aliyense akudziwa kuti pali mwachindunji ndi alternating panopa. The chachiwiri chimagwiritsidwa ntchito magetsi zosinthika ake akhala mosavuta kusintha ndi Motors pa maziko ake ali ophweka ndi odalirika kwambiri.

Alternating apano - gulu la particles mlandu kudzera wochititsa, amene mosinthanasinthana ena nthawi (nthawi) lisinthike malangizo ndi udzakwaniritsidwa. Wotchuka sine yoweyula zikungosonyeza khalidwe lake. Kumvetsa chiyambi cha alternating panopa, kuganizira mfundo losavuta ikuyambitsa chipangizo. Bukuli lili pa chodabwitsa cha kupatsidwa ulemu atomu, chomwe mu maonekedwe a masiku ano ndi kuzungulira chatsekedwa conductive amene intersects mizere ya mphamvu maginito.

Nguli, pakati pa awiriwa mizati maginito (kumpoto ndi kum'mwera) anayikidwa chimango zakuthupi conductive (mkuwa waya). malekezero ake kudzera mwa kutsetsereka kulankhula za limagwirira burashi olumikiza katundu dera kapena chipangizo voteji chingwe. chimango akhoza atembenuza padziko olamulira, chimene lilipo. Pakati pa mizati maginito pali wosaoneka maginito mizere. Pamene chimango ndi zimayenda, mbali zonse ziwiri malire, chifukwa mu alternating panopa. chifukwa pakuwonekera kwake amayamba ndi "kugodomalitsa" ya maginito ya elekitironi m'mipita lakutali ku phata la. Ngakhale malangizo a pa EMF (electromotive mphamvu) mu zigawo ziwiri mtanda wa chimango ndi nthawi zosiyana, ngati inu mutayang'ana pa unyolo wonse, zimaonekeratu kuti ali unidirectional. EMF kufika pazipita panthawi ya mphambano ya mizere ofukula mphamvu ndi umadutsa ziro pa yopingasa malo malo mafelemu (timakumbukira sinusoid, kumakhalanso nthawi mitanda phindu ziro). Ndicho mophweka.

Inde, magudumu weniweni, kupoletsa ndi alternating panopa, ndi zovuta kuposa chimango cha waya, koma mfundo ya ntchito n'chimodzimodzi. Anchor ndi windings (kwenikweni - ndi kuchuluka kwa mafelemu Buku) imazungulira mu mphamvu ya maginito a stator kunja mphamvu: angakhale ndi mphamvu ya madzi kugwa; kayendedwe nthunzi kwaiye kutentha kwa riyakitala nyukiliya; mphepo kuthamanga, ndi zina zotero. The voteji chifukwa zikuoneka pa malo kumulowetsa. Mpaka kugwirizana katundu ndi AC sanatenge nthawi yaitali. Kawirikawiri kwaiye osati mmodzi koma magawo atatu.

Monga tanenera kale, kuwonjezera variable, ndipo pali panopa zonse. Dzinali odziwikiratu: palibe kusintha mu malangizo a gulu zimachokeradi. panopa Izi nthawi zonse anawauza ku kuphatikiza ndi opanda. The owonjezera mphamvu, monga mabatire, mwa zochita mankhwala kudziunjikira palokha amenewa panopa, choncho kalembedwe "+" ndi "-". Poyerekeza ndi variable, ndi angapo mbali. Ine ndikufuna kunena "mphamvu ndi zofooka", koma si - ndi "peculiarities". Mwachitsanzo, DC galimoto limachititsa bwino kusintha liwiro kasinthasintha wa armature, osati stepwise, makamaka pafupipafupi converters ntchito zovuta poponya. Komanso, pafupifupi onse madera pakompyuta tinapangidwa ntchito ndi mtundu uwu wa mphamvu monga iwo savuta kusamalira. Pezani panopa mwachindunji ku AC lophweka - m'pofunika "kulungamitsa" michenga yopangira zida zamagetsi zigawo wapadera (diodes ndi diode milatho). Zimachitika kagawo sinusoid nsonga ziwiri mmasiku Awiri theka. Otsala kugunda chikhalidwe cha panopa chifukwa akhoza kukhala yosalala.
