Brushless motor - ubwino ndi ntchito

The brushless motor ili ndipamwamba kwambiri - pafupifupi 93%. Iye akhoza kukhala ndi mphamvu zambiri. Ntchito yake yaikulu ndi kusakhala ndi msonkhano wa burashi, womwe umangowonjezera kudalirika. Pankhaniyi, moyo wa chipangizocho umadalira pa moyo wake wokha. Ndizochepa phokoso poyerekeza ndi magalimoto osonkhanitsa. Chifukwa cha katundu wawo, apeza ntchito yaikulu. Mwachitsanzo, iwo ali mbali ya magetsi otsekemera mu mafakitale a mafuta ndi gasi, popeza alibe misonkhano yotsitsa, kotero palibe kuphulika. M'magalimoto ogwiritsa ntchito magalimoto, amagwiritsidwa ntchito ngati injini za wipers zowonjezera mphepo, opisa mawindo. Amagwiritsidwanso ntchito mu zipangizo zachipatala, robotics.

Chofunika kwambiri ndi chakuti brushless motero ndi makina a DC omwe ali ndi inductor - rotor ndi mpweya wopangidwa ndi stator. Ntchito ya nkhono ya burashi yomwe ikusowa imayendetsedwa ndi mawotchi a semiconductor, omwe amapereka zida zowonjezera mmwamba ndikuzisintha mogwirizana ndi malo a rotor. Njira yowonjezereka ndi injini ya brushless yomwe ili ndi magawo atatu otchedwa stator.

Chowongolera chitha kuyimira mitundu yosiyanasiyana, malingana ndi malo a magetsi pa iyo. Chifukwa cha kugwirizana kwa magnetic fluxes, mphukira imachokera ku stator ndi rotor. Pothandizidwa ndi magetsi oyendetsa malo, mpata pakati pa maulendo awiri udzasungidwa mu 90 °, zomwe zidzapangitse mtanda wopambana. Mpweya wa stator ukhoza kuperekedwa kuchokera kwa aliyense wotembenuza semiconductor.

Kupanga makina opangidwa ndi brushless motors

Zipangizozi ndizokongola kwambiri kwa oyendetsa ndege, popeza mkati mwa masekondi pang'ono amapeza maulendo apamwamba. Akuyesera kupanga moto wamtundu wa manja ndi manja awo pakhomo, monga momwe malonda ogulitsira malonda aliri ndi okwera mtengo kwambiri. Thupi, monga lamulo, limachokera ku duralumin. Maginito amachotsedwa ku CD-driy akale.

Mawotchi oterewa ali ndi mapaundi awiri kapena asanu ndi awiri. Stator ili ndi thupi, komanso lachimake, lomwe limapangidwa ndi zitsulo zamagetsi ndi mkuntho wamkuwa, umene umagwirizana ndi malo ozungulira omwe ali pamtunda. Chiwerengero cha mphepo imayenderana ndi chiwerengero cha magalimoto, ndipo akhoza kukhala gawo limodzi, awiri, atatu kapena atatu. Kusinthana pakati pa windings kumachitika ndi maulendo apakompyuta - osokoneza. Chida chonsecho chasonkhanitsidwa motere:

- maginito amaikidwa mu dongosolo lolondola;

- ulusi umadulidwa pamthunzi;

- mabowo ena amadzikongoletsera kuti athe kulemera ndi kuzirala;

- stator ikuwombera ndi waya wamkuwa ikuchitidwa;

- Sungani zolumikiza;

- zilembo zimayikidwa;

- mphete zowonjezera zimayikidwa.

Komanso, misonkhanowu yowonongeka imagwirizanitsidwa ndi magetsi ndipo ikuyendetsedwa. Ngati chirichonse chikugwira ntchito bwino, ndiye mukhoza kuchiyika pa chitsanzo cha ndege. Choncho, makina opangidwa ndi brushless omwe amadzipanga okha amatha kupanga.
