Kodi mungayendetse bwanji mota yopanda maburashi ya dc? Njira zitatu zowongolera liwiro la mota yopanda maburashi | LEADER

Kodi zimatheka bwanjidc mota yopanda burashiliwiro lowongolera? Ambiri amayamba kugwiritsa ntchito upangiri wa makasitomala a injini yopanda maburashi, vuto la injini yopanda maburashi kwambiri m'zipatala, zida zodziyimira pawokha, maloboti, ndi magalimoto pantchito, kuti akwaniritse njira zosiyanasiyana zowongolera kuyendetsa, kuwongolera liwiro la liwiro la galimoto yopanda maburashi ya DC ndi vuto la kuyendetsa bwino & koipa kumakhala ndi mafunso ambiri,fakitale yogwedeza ya injinikugawana kuwongolera liwiro la injini yopanda brushless njira zitatu:

Njira yowongolera liwiro la mota ya brushless dc

Njira 1: Gwiritsani ntchito magetsi kuti muwongolere liwiro, mphamvu yamagetsi imayendetsedwa makamaka ndi mphamvu yamagetsi, nthawi zambiri pogwiritsa ntchito dalaivala wofanana ndi injini, kusintha mphamvu yamagetsi yotuluka ya dalaivala kumathanso kuwongolera liwiro la mota yopanda brushless, ngati palibe dalaivala, mukufuna kuwongolera mota, muyenera kuwona mphamvu ndi mphamvu yamagetsi yogwira ntchito ya mota.

Njira yachiwiri: Kuwongolera liwiro la PWM, mfundo yowongolera liwiro la PWM ya mota ya dc ndi mfundo yowongolera liwiro la mota ya ac ndi yosiyana, si njira yosinthira liwiro la mota mwa kusintha pafupipafupi, koma kudzera mu kusintha njira yoyendetsera magetsi, ndikugwirizana ndi zida zina zosungira mphamvu mu circuit, kusintha kwa mphamvu yamagetsi, kuti tikwaniritse cholinga cha kusintha kwa liwiro la mota ya dc yopanda brushless. Imasinthidwa ndi kusintha kwa mphamvu. Pali njira ziwiri zowongolera PWM:

1. Chizindikiro cha PWM chimagwiritsidwa ntchito kuti chiwongolere nthawi yoyendetsera transistor. Nthawi yoyendetsera ikakhala yayitali, nthawi yogwirira ntchito idzakhala yayitali, ndipo liwiro la mota lidzakhala lalikulu.

2. Chizindikiro chowongolera cha PWM chimagwiritsidwa ntchito kuwongolera nthawi yoyimitsa ma triode, ndipo mphamvu yowongolera imasinthidwa kuti izi zitheke.

Njira 3: ngati ndi yolondolamota yamagetsi yaying'onoLiwiro lingagwiritsenso ntchito kukana (sikoyenera, njira yake ndi yosavuta, njira yotsatizana ndi potentiometer, njira iyi yokha ingachepetse kugwira ntchito bwino, chifukwa chake siilimbikitsa), liwiro lolamulira lamphamvu kwambiri la mota silingathe kukana, chifukwa limafuna kukana pang'ono kwamphamvu kwambiri (kukana kugwira ntchito kwa mota ndi kochepa kwambiri), kukana ndikovuta kupeza ndipo magwiridwe antchito ake ndi otsika kwambiri, ndibwino kupezabe ma drive a DC opanda brushless.

Ndikukhulupirira kuti njira zitatu zomwe zili pamwambapamota yopanda burashi ya dcKuwongolera liwiro kungakupatseni thandizo ndi chilimbikitso.

Zomwe zili pamwambapa zikunena za brushless dc motor speed regulation ya njira zitatuzi, ndikukhulupirira kuti muli ndi thandizo; Ndife a microfakitale yamagalimoto ogwedera, zinthuzo ndi izi:mota yozungulira yogwedera,injini ya kugwedezeka ya iphone 6s,injini ya kugwedezeka ya iphone 7;Tikukhulupirira kuti mutha kulumikizana nafe!
