Te ia o te whanaketanga motuka dc korepara

Ko te motuka dc Brushless e kore e pupuri noa i te motika dc tuku iho kia pai te whakahaere me te hihiri, te hanga ngawari, te mahi pono, te ngawari ki te whakahaere. Ko tana tono mai i te umanga hoia tuatahi, aerospace, rongoa, korero me nga taputapu o te whare tae atu ki te whanaketanga tere o te mara automation ahumahi.

dc motor me ona āhuatanga taipana pai kua whakamahia whānuitia i roto i te mara o te mana motopaika, engari na te whakahuri miihini me te paraihe motika dc noa, ka taea te * rerekee ira, me tiaki i nga wa katoa; Te whakaputa wawaotanga electromagnetic i roto i te wahanga haruru nui, ka pa ki te tono atu o te motuka dc i roto i te punaha whakahaere.

ki te hinga i te commutation mihini o hapa, na roto i te commutation hiko whakakapi te commutation mihini o brushless motoka puta i te wa o mua. Ko Harrison me etahi atu mo te wa tuatahi i tono ki te whakakapi i te iahiko whakawhiti paraihe miihini me nga patent transistor, e tohu ana i te whanautanga o te motini paraihe kore.

me te whakawhiti hiko o te motini dc brushless kua tino uru ki roto i te waa mahi, i te tau 1978 te motini DC brushless MAC me te puku ki te whakarewa. Whai muri i te whakahaerenga o te motini dc brushless o te ao ki te rangahau tino, ka whanakehia e ChengFangBo te motini paraihe korepu dc me te ngaru hiko.

20 tau, me te aukume tuturu rauemi hou, hangarau microelectronics, hangarau mana aunoa me te hangarau hiko hiko ina koa te whanaketanga taputapu whakawhiti mana teitei, ka tere te ahunga whakamua o te motuka korepu. Ko te motini dc paraihe ehara i te mea motuhake ki te whakawhiti hiko o te motini dc, engari e pa ana ki te motini dc paraihe te ahuatanga o waho o te motuka whakawhiti hiko.

i roto i te hanganga, me te motini dc paraihe, karekau dc motor stator awhiowhio rite te armature, whakakapia e te aukume whakaihiihi awhiowhio pūmau. E ai ki te rerenga o te ngaru o naianei awhiowhio ringa, ka taea te wehea te motini dc brushless ki te ngaru tapawha brushless dc motor (BLDCM)Dc motor me te ngaru sine, 永磁同步电动机), BLDCM commutation hiko ki te whakakapi i te taketake dc motor commutation mihini, mahia e te rotor aukume tuturu, elimina; Kei te whakakapihia e te pukoro matihiko katoa te awhiowhio o te rotor motuka tukutahi ki te aukume tuturu, ka whakakore i te awhiowhio o te mara, te mowhiti paheke me te paraihe. I roto i te taua huru, te ara iahiko taraiwa mo te ngaru tapawha ngāwari ake, me te ngāwari ki te whakahaere, na te tono o te BLDCM he fuzzy katoa-mamati ki te whānui ake.

motini dc brushless na roto i te hiko commutation circuit te nuinga, te rotor position detection circuit and motor ontology of three parts, hiko commutation circuit te tikanga kei roto i te mana whakahaere me te waahanga taraiwa, a ko te kimi i te tuunga rotor ka whakamahia i te nuinga o te waa ki te whakaoti. Mahi, te kaiwhakahaere rite ki te tūnga o te pūoko tūnga rotor nekeneke me te raupapa keu iahiko taraiwa o ia ngongo hiko, he raupapa i roto i te rere, ki te pei i te nekeneke dc. I roto i tenei pepa, mai i nga wahanga e toru o te motini paraihe kore ki te tātari i tona whanaketanga.
