Te whanautanga o te motini dc brushless me te tukanga whanaketanga

Brushless dc mīhini hiko ki o ratou āhuatanga pai kua whakamahia whānuitia i roto i te mara o te mana puku, engari e tika ana ki te whakakā mīhini me te paraihe motika dc noa, rawakore pono, me tiaki auau; 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. Ko te whakawhiti miihini ka kawea mai kia taea ai te hinga i nga ngoikoretanga, i roto i te whakawhiti hiko ka whakakapi i te huringa miihini o te motuka dc brushless ka ara ake i te waa 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 motuka dc brushless hou. Mo te whakawhiti hiko o te motini dc brushless ki roto i te waahanga mahi, i te tau 1978 te miihini MAC korepu dc me te puku ki te whakarewa. Whai muri i te mahi rangahau tino rangahau a te motini paraihe korekore o te ao, ka whanake haeretia a ChengFangBo motini paraihe kore motika dc me te ngaru 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 wehe i 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 miihini, mahia e te rotor aukume tuturu, elimina; Kei te whakakapihia e te fuzzy mamati-katoa te awhiowhio o te rotor motika tukutahi me 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 ko katoa-mamati fuzzy 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 te nuinga o te pukoro tuunga hei whakaoti. Mahi, te kaiwhakahaere rite ki te tūnga o te pūoko tūnga rotor nekeneke me te raupapa keu iahiko taraiwa o ia ngongo hiko, me te raupapa i roto i te rere, ki te pei i te nekeneke dc.



na te mea he mea hou aukume tuturu, hangarau microelectronics, hangarau whakahaere aunoa me te hangarau hiko hiko ina koa te whanaketanga taputapu whakawhiti mana teitei, ka tere te ahunga whakamua o te motuka korepu. Ehara i te mea motuhake te motini dc paraihe 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. Brushless dc motor e kore anake e pupuri i te pai hihiri, me te pateko āhuatanga mana tere nekeneke dc tuku iho, me te hanganga ohie, mahi pono, ngāwari ki te whakahaere. Ko tana tono mai i te umanga hoia tuatahi, rongoa, korero, aerospace, taputapu whare tae atu ki te whanaketanga tere o te mara automation ahumahi.
