Momwe mungathamangire dc brushless mota? Njira zitatu zowongolera kuthamanga kwa mota ya brushless | Mtsogoleri

Zikuyenda bwanjidc brushless motaKuwongolera liwiro?Ambiri amayamba kugwiritsa ntchito kukambilana kwamakasitomala a brushless motor, vuto la brushless motor kwambiri muzachipatala, zida zodzichitira okha, maloboti, ndi magalimoto pamagwiritsidwe ntchito, kuti azindikire kuwongolera kosiyanasiyana, kuwongolera liwiro la mota ya brushless dc. liwiro ndi zabwino & zoipa pagalimoto vuto ali ndi mafunso ambiri, ndivibrating motor fakitalekugawana ulamuliro wa brushless galimoto liwiro njira zitatu:

Njira yoyendetsera liwiro la brushless dc motor

Njira 1: gwiritsani ntchito voteji kuti muwongolere liwiro, torque imayang'aniridwa kwambiri ndi pano, nthawi zambiri yokhala ndi dalaivala wofananira, sinthani voliyumu ya dalaivala imathanso kuwongolera liwiro la mota ya brushless, ngati palibe dalaivala, mukufuna kuwongolera motere, muyenera kuwona mphamvu ndi momwe zimagwirira ntchito.

Njira 2: Kuwongolera liwiro la PWM, PWM kuwongolera liwiro la dc motor ndi ac motor speed control mfundo ndi yosiyana, sikuti ndi njira yosinthira pafupipafupi kusintha liwiro lagalimoto, koma kusintha njira yoyendetsera voteji kugunda m'lifupi, ndikugwirizana ndi zigawo zina zosungirako mphamvu zozungulira, kusintha kwa amplitude ya armature voteji, kuti mukwaniritse cholinga cha brushless dc motor speed change. Imasinthidwa ndi matalikidwe Pali njira ziwiri zowongolera PWM:

1. Chizindikiro cha PWM chimatengedwa kuti chiwongolere nthawi yoyendetsa transistor. Kutalika kwa nthawi yoyendetsa galimoto, nthawi yogwira ntchito idzakhala yotalikirapo, ndipo kuthamanga kwa galimoto kudzakhala kokwera.

2. Chizindikiro chowongolera cha PWM chimagwiritsidwa ntchito kulamulira nthawi ya triode pa nthawi yopuma, ndipo magetsi owongolera amasinthidwa kuti akwaniritse izi.

Njira 3: ngati ndi agalimoto yamagetsi yaying'onoKuthamanga kungagwiritsenso ntchito kukana (sikuvomerezeka, njirayo ndi yosavuta kwambiri, mndandanda wa potentiometer ukhoza, njira iyi yokha ingachepetse mphamvu, choncho sichimalimbikitsa), kuthamanga kwamphamvu kwa galimoto sikungathe kukana, chifukwa kumafunika kukana kwamphamvu kwakung'ono (kukana kugwira ntchito kwagalimoto ndikocheperako), kukana ndikoyipa kupeza ndipo njira yothetsera vutoli ndiyotsika kwambiri, ndibwino kupezabe ma drive a brushless dc.

Ine ndikuyembekeza pamwamba njira zitatu zadc brushless motakuwongolera liwiro kungakupatseni chithandizo komanso kudzoza.

Zomwe zili pamwambazi ndi za brushless dc motor speed regulation ya njira zitatuzi, ndikuyembekeza kuti muli ndi chithandizo; Ndife ochepa.vibration motor fakitale, mankhwala ndi:linear vibration motor,iphone 6s vibration motor,iphone 7 vibration motor;Ndikukhulupirira kuti mutha kulumikizana nafe!
