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

brushless dc pūmana nekeneke 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 pokanoa hiko i roto i te haruru o te wahanga he nui, ka pa ki te tono atu a te kaiwhakahaere motuka dc ki te punaha whakahaere. Ko te whakawhiti miihini ka kawe mai kia taea ai te hinga i 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 brushless kei roto tonu i te waahanga mahi, i te tau 1978 te MAC classic o te mana whakahaere 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 ngaru hiko dc. 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, whakakapia e aukume pūmau excitation awhiowhio. E ai ki te rere o te ngaru o naianei awhiowhio ringa, ka taea te wehea te pūmana 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, elimi aukume rotor; 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. 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, hiko 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 iahiko taraiwa taraiwa o ia ngongo hiko, he pai te rere, hei peia te motini dc. Ka rite ki te rauemi aukume pūmau hou, hangarau microelectronics, hangarau mana aunoa me te whanaketanga o te hangarau hiko hiko rawa teitei te mana whakawhiti whakaaro, brushless pūmana motopaika whiwhi whanaketanga tere. Ehara i te mea motuhake te kaiwhakahaere motika dc Brushless ki te kaiwhakahaere whakawhiti hiko o te motini dc, te pūmana motini dc brushless engari e kii ana he ahuatanga o waho o te kaiwhakahaere motuka whakawhiti hiko. Brushless dc motor pūmana e kore anake e pupuri i te motika dc tuku iho pai pateko, me te hihiri whakahaere whakahaere, hanga 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.
