Ako i te rahinga whakauru o te momo-kore whakauru noa . A pee i te kaiwhakanao hiko (ngaio tukua: pūpoapoa axial, i pūpoapoa toropā) ki te ako:
He rereketanga o te aratau rereke: He tohu tohu rite te rahi me te ahunga ki te ritenga o nga raina tohu rerekee e whakamahia ana i te ara iahiko
Ko te au, mo te raina tohu, ko te ia e rere ana i waenga i te raina tohu me te papa tohu.
He mahinga noa: He rua tohu (he reo ranei) he rite te rahi me te ahunga o nga raina tohu rerekee. I te ara iahiko,
Te tikanga, ko te haruru o te whenua e tukuna ana e te aratau noa, na reira ka kiia hoki he haruru aratau noa.
He maha nga huarahi hei pehi i te haruru o te aratau-noa. Hei taapiri ki te whakaheke i te haruru o te aratau i te putake, ka whakamahia te whakauru noa ki te taatari i te haruru o te aratau-noa, ara ki te aukati i te haruru o te aratau mai i te ara iahiko. Ko te tikanga, ko te aratau noa e haehae ana i roto i te raupapa taiawhio. Ko te kaupapa ko te whakapiki i te aukati o te ara-ara noa kia pau ai te aratau-noa nei, kia aukatihia (e whakaatahia ana) e te koka, na reira ka pore i te haruru o te ara i roto i te ara iahiko.
Ko te maataapono o te aratau-noa o te koroa o te tangata whakauru ranei
Mena ka werohia nga taera e rua i te ara ano i runga i te mowhiti aukume o etahi mea aukume, ka hangaia te rerenga aukume i roto i te koina na te whakauru hiko i te wa e huri ana te waa i waenga i te koina. Mo nga tohu aratau rereke, te rerenga aukume i hangaia e he rite te rahi o te mowhiti aukume me te anga whakamua, me te whakakore e rua tetahi ki tetahi, no reira ko te aratau rerekee i hangaia e te mowhiti aukume he iti rawa. Mo nga tohu noa-ahua, ko te rerenga aukume i hangaia he rite te kaha me te ahunga, a ko nga mea e rua ka taapiri ki a ratau ano ki te whakaputa i te koretake-noa o te mowhiti aukume. Ko tenei ahuatanga ka iti ake te awe o te momo aratau noa ki te tohu aratau rerekee ka pai ake te taatai i nga mahi ki te haruru o te aratau noa.
(1) Ka puta ana te rereketanga o te waa i roto i te kohinga aratau noa, kei te anga ke te raina aorangi a ka ngoikore te papa aukume Ka kitea mai i te ahunga o te raina mara aorangi i te ahua i raro ake nei ko te pere raina totoka e tohu ana i te ahunga o te au a ko te raina taia e tohu ana i te ahunga o te papa aukume
(2) Ko te waa-noa e haere ana i roto i te kohinga aratau noa, a ka whakapakarihia te maaka aukume na te mea ano o te raina papa aukume. Ka kitea mai i te ahunga o te raina papa aukume i te ahua i raro ake nei ko te pere raina totoka e tohu ana i te ahunga o te au a ko te raina taia e tohu ana i te ahunga o te papa aukume
Ko te whakakakahu-noa i te koina e kiia ana ko te whakarea whakauru-takitahi, e mohio ana taatau ko te whakauru he whakaputa i te kaha o te papa aukume, te aratau noa, te porohita aratau noa ranei, ka rere ana te ahua-noa i roto i te roera, na te nga raina aorangi i te ahunga kotahi, me te kore e whakaarohia i raro i te ahuatanga o te turuturu, te aukume o te aukume, ko tana kaupapa he takirua, i raro ake i nga raina porowhita auri i roto i nga raina puru puru, whero me te kikorangi na roto hoki i te pōkai whero, whakauru tetahi ki tetahi.
From the point of view of inductance, inductance is multiplied, magnetic chain represents the total magnetic flux, the common-mode inductor, when magnetic flux is doubled, circle number has not changed, the current didn't also did not change, so mean increased inductance for 2 times, means that the equivalent permeability into 2 times.
Me pehea e taea ai te rerenga o te uruhanga rite? Mai i te tauira whakauru e whai ake nei, mai i te maha o nga hurihanga N kaore e rereke, ko te hiko aukume me te waahanga whakawhiti o te waahanga aukume e whakatauhia ana e te rahi o te tinana o te aukume, no reira kaore he rereke. Ko te take noa ko te uruhanga U ka taarua, kia kaha ake ai te rere o te aukume
Common-mode inductor in common mode, therefore, when an electric current passes through, work under the mutual inductance model, under the effect of mutual inductance, the equivalent inductance is cost increase, therefore common mode impedance will be multiplied, and the common mode signal has good filtering effect, also is the common mode signal with large impedance block, don't let it pass the common-mode inductor, also is not to let this signal transmission to the next level of the circuit, the following is the inductive reactance ZL.
Know common-mode inductor under the mode of common mode inductance, is the main clue to know mutual inductance, magnetic components of all, no matter what name as long as mastering the form of the change of the magnetic field, magnetic field changes through the phenomenon to essence, also easy to understand, moreover we always grasp the magnetic field lines, it is our understanding the visual form of the magnetic field, consider whether the same side or different name or concept of the mutual inductance phenomenon or magnetic field, we are drawing the lines of magnetic force to realize their - master "magnet winding method" is explained before.
