Brushless dc pūmana nekeneke whakaurua atu mahi, kia te pūmana nekeneke he ake te ahunga whakamua

Brushless dc motor controller integrated more functions, make the motor controller more progress related to the one hundred-year - old has a motor controller, the brushless dc motor controller is more efficient and more small and lighter volume, and is steadily development forward fast. No te mea he pumau ratou me te piki haere o te rongonui, kei te huri hei reanga hou. E rua noa nga tau ki muri, he nui ke atu te utu o te kaiwhakahaere motopaika dc brushless atu i te miihini miihini paraihe. Engari he mihi ki te hoahoa i te ahunga whakamua o te hangarau me te hangarau rauemi, kua heke iho ona utu. I tenei ra, ko te rereketanga o te utu i waenga i nga momo hangarau e rua mo te motuka motuka he 10%. A ko te huringa tino nui ko nga kaihoahoa i timata ki te mahi tata ki te tono ahumahi. I nga wa o mua, e kiia ana no te kaitoha motika momo uaua te mara tono, na te mea ko te 'ma' ehara i te taiao mahi tino nui. Engari inaianei, na te iti o te utu, te kaitahuri motuka kore, ka whiwhi tono hou. Ko te paraihe me te pūmana motopaika kore he tino rerekee ahakoa he paraihe noa -Ko te commutator (刷子,换向器). Ahakoa ko te kaiwhakahaere motini korepu na te pūoko o te whare (霍尔传感器)Whakahokia te ara iahiko mana urupare tūnga rotor, kia taea e ia te ako i te wahanga whakamuri i te motuka motuka (Ota)Te tika o te waa. Ko te nuinga o nga miihini miihini korepu e hanga ana i nga kaiwhakatakoto tuunga whakangao e toru nga pukoro paanga o te whare. I te mea karekau he paraihe motika motopaika, na reira karekau he atanga e tika ana, na reira he pai ake, he iti te haruru, whakamahia i nga waa noa kaore he hohonu o te tiaki, he roa ake te ora. Na, he aha nga mea kei tua atu? Ahakoa ka hohonu ake te mohiotanga o te kaiwhakahaere motopaika o te umanga miihini korepu motika, engari i tenei wa he iti tonu te mahi ki te whakawhanake i te pukoro motika miihini korepu motika hei whakahaere i nga waahanga hiko. I tenei wa ki te kaiwhakahaere motuka me te motuka taraiwa taraiwa te tono whanaketanga kaari taraiwa, ka taea e ratou te whakarato ki nga kaihoahoa me te miihini miihini, te kaha o te kaupapa me te taraiwa, a ko enei mahi katoa ka whakauruhia ki roto i te kete kotahi. Ahakoa i roto i te aratau mamati, tairitenga ranei, ko te tikanga tenei huarahi whakauru ki te whakaoti i nga tono katoa e tika ana mo te commutator motuka. Ki te kore tenei whakaurunga, karekau e mahi te kaiwhakahaere motopaika kore. I te wa e whiriwhiri ana i te taraiwa pai rawa atu, ko te whakarereketanga o te whanui puihi (脉宽调制) ka mohiohia ko te IC tetahi o nga hangarau pai. Ka whakawhirinaki anake ki te kowhiringa o te tino pai o te puku. Ara iahiko raina ki te whakanui i nga ngoikoretanga i te mutunga, ko te taumata whakaputa he 50%. I roto i tenei hiko whakaputa i nga wa noa, ko te impedance o te huānga bypass he rite ki te impedance kawenga, ko te tikanga ko te wera i hangaia e te whakanui he rite ki te kawenga hiko! I roto i te poto, ka te reo taraiwa taumata mana ki te kawenga ātete, ara iahiko mana rārangi i roto i te tōtika o 50%. Inaianei kia whakaarohia he otinga PWM. I roto i te punaha whakahaere PWM, ka hurihia te taumata whakauru whaihanga ki te tohu puku huringa huringa mahi rereke. Mai i te whakawhiti hiko ki tetahi atu ahua o te tukanga, kei waenganui i te OFF me te ON e kiia ana ko te 'modulation', koinei hoki te hangarau e kiia nei ko te 'whakawhitinga whanui whanui'. I te tauwehenga mahi tuatahi ko te kore, ara, kua noho i te ahua OFF, ka timata te hurihanga o te motuka motuka, te kawenga, te piki ake i nga wa o mua, tono tae noa ki te motuka motuka ki te whakatutuki i te tere e hiahiatia ana me te / ranei. Ka noho tonu te patai, he aha nga mahi hei mahi tonu? He mea tika ki te whakahaere i te mana whakahaere motika moroiti o te mahi motuhake o te kaiwhakahaere moroiti, me te whakarato i te kaha ki te kaiwhakahaere motopaika me te kaiwhakahaere moroiti me te atanga i waenga i te kaitahuri miihini miihini PWM IC taraiwa kua timata ki te puta. Engari ki te whakarato i nga kaihoahoa inaianei me uru wawe ratou ki te whakauru i nga mahi ara iahiko kore paraihe, he nui tonu nga mahi hei mahi i tenei mara.
