Ko te whanautanga o te kaiwhakahaere motika dc brushless me te tukanga whanaketanga

brushless dc pūmana motopaika ki o ratou āhuatanga pai kua whakamahia whānuitia i roto i te mara o te mana puku, engari te noa e tika ana ki te whakakā mīhini me te paraihe dc pūmana motopaika, rawakore pono, me tiaki auau; Te whakaputa i te wawaotanga hiko i roto i te haruru o te wahanga he nui, ka pa atu ki te tono atu a te kaiwhakahaere motuka dc ki te punaha whakahaere. Ko te whakawhiti miihini ka kawe mai kia hinga ai nga ngoikoretanga, i roto i te whakawhiti hiko ka whakakapi i te huringa miihini o te kaitahuri 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 ara iahiko whakawhiti paraihe miihini me nga patent transistor, e tohu ana i te whanautanga o te kaiwhakahaere motuka dc brushless hou. A ko te whakawhiti hiko o te kaitahuri motuka dc korepu ka uru ki roto i te waahanga mahi, i te tau 1978 ko te MAC matarohia o te kaitaraiwa motuka dc brushless me te taraiwa. Whai muri i te rangahau tino rangahau a te kaiwhakahaere motopaika korepu o te ao, kua whanaketia e ia a ChengFangBo te kaiwhakahaere motopaika paraihe kore me te ngaru hiko hiko dc ngaru kore. I roto i te hanganga, ki te paraihe dc pūmana nekeneke he rerekē, te stator awhiowhio o te brushless dc pūmana motopaika rite te armature, whakakapi e te aukume pūmau excitation awhiowhio. E ai ki te rere o te ngaru o naianei awhiowhio ringa, ka taea te wehea te pūmana motuka dc brushless ki te ngaru tapawha brushless dc motor (BLDCM)Dc motor me te ngaru hiko,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, elimi aukume rotor; 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. Brushless dc pūmana motopaika i roto i te whānui ma te hiko commutation circuit, te rotor position detection circuit and motor controller ontology of three parts, hikohiko commutation circuit te tikanga kei roto i te mana whakahaere me te waahanga taraiwa, a ko te kimi i te tuunga rotor e whakamahia ana i te nuinga o te waa ki te whakaoti. Ko te mahi, ko te kaiwhakahaere i runga i te tuunga o te pukoro i whanganga i te tuunga rotor motika kia taea ai te whakaoho i te ara iahiko taraiwa o ia ngongo hiko, he pai te rere, hei peia te motuka dc. Ka rite ki te rauemi aukume pūmau hou, hangarau microelectronics, hangarau mana aunoa me te whanaketanga o te hangarau hiko hiko rawa teitei mana whakawhiti whakaaro, brushless pūmana motopaika whiwhi whanaketanga tere. Ehara i te mea motuhake te kaiwhakahaere motika dc kore ki te mana whakawhiti hiko o te motini dc, te pūmana motini dc brushless engari e kii ana he ahuatanga o waho o te pūmana nekeneke hiko. Brushless dc motor pūmana e kore anake e pupuri i te motika dc tuku iho pai pateko, me te hihiri whakahaere whakahaere, 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.
