DC motor - me collectron brushless ahua

Ka taea te wehea waka hiko ki e rua ngā momo rite ki o ratou whakaaro: he generator ko DC nekeneke. Noatia, mahi tata ōrite ratou. Ko te rerekētanga anake ko e te generator tahuri te pūngao pūkaha o te rotor i te papa autō whakaputaina e te stator awhiowhio i hiko me te pūkaha - i runga i te anga ke (e tahuri pūngao hiko ki te pūngao hurihuri, i.e. aunoa).

Ko te pūkaha DC kua he armature ki awaawa i roto i ona conductors tāpae i roto i to ratou hanganga. Ko te wāhanga matua tuarua o tenei mīhini ko tona awhiowhio te me stator excitation ki amo maha. Ko te parau tumu o te mahi o te pūrere taua he tino ohie. Na roto i te haere i roto i te tihi waea o armature DC nāianei i roto i ngā tohutohu rerekē (kotahi taha "tatou" me te tahi atu "ki runga ki a matou"). E ai ki te pai-mohiotia tikanga maui-ringa, ka aua conductors e te hunga i te tihi, kia panaia atu o te stator papa autō i hanga e te maui, me te kaiwhakahaere tikanga i te raro o te armature, ka kia panaia ki te tika.

Mai conductors parahi whakatakotoria i roto i te awaawa, ka te kaha pānga kia whakawhiti ki te punga, a tītaka reira.

A, no te kotahi wahi o te provernetsya kaiwhakahaere, me te tu ritenga i te pou tonga o te stator ki te tīmata i te mahi braking (tīmata kaiwhakahaere aki ki te taha ki maui). Kia kore ai tenei tukanga ko reira e tika ana ki te huri i te aronga o te nāianei i roto i te waea. Hoki tenei whakaaro, ka karanga pera-ka karanga te maha, me te pūkaha ki te parau tumu o te mahi te commutator DC nekeneke.

ka tuku te reira i kopiko armature taipana ki te take pūkaha, me te kotahi - whakaturia i roto i te nekehanga i te taputapu mīhini tika. Me kï reira e hāngai ana te parau tumu katoa o tenei taputapu kei i runga i te koaro o te DC i te mekameka punga.

Heoi, i reira te mea he pūkaha brushless DC. I roto i te rerekē ki te tango, e kore e whai te reira i tona pūrere i roto i brushes e hanga mōrearea atu i roto i te mahi pūkaha (mirimiri brushes ki te rotor hurihuri a taea te whakaputa koraahi e ai whakakā painga kiriweti wāhanga mīhini hiko).

dc pūkaha kahore kaikohi he i roto i ona ahunga hoahoa me pūmana motuhake programmed ki te whakarato i te tukanga whakawhitinga katoa i roto i te pūkaha. I tua atu, kua reira microactuators ki tiketike-pū tūnga.

Ko te aha e utu tino nui atu i te tikanga motors paraihe DC he pūrere taua. Heoi, kei te tino tika ai te whakamahi o te pūkaha taua: ki te whakanui i tona mauroa, tika, te haumaru. Tino teitei me te tōtika (COP), me te ātete ki overloads.

Haunga te commutator DC nekeneke, e tōtika whakahou tauira brushless faahope te tonu whakahoutia. Hei tauira, tino tata whakawhanakehia whakapā-kore toru-wāhanga dc pūkaha, kahore te kaikohi.
