Momwe mungathamangitsire ma mota a BLDC?

1. Kuwongolera liwiro la Voltage
Kuwongolera liwiro la Voltage ndiye njira yosavuta yowongolera liwiro, yomwe imawongolera kuthamanga kwagalimoto posintha ma voliyumu amagetsi a DC. Mphamvu yamagetsi ikawonjezeka, kuthamanga kwa injini kumawonjezekanso; Kumbali ina, pamene voteji amachepetsa, liwiro la galimoto adzachepanso. Njirayi ndi yophweka komanso yosavuta kugwiritsa ntchito, koma kwa ma motors apamwamba kwambiri, zotsatira za kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe kake

2. PWM liwiro lamulo
Kuwongolera liwiro la PWM (Pulse Width Modulation) ndi njira yodziwika bwino yoyendetsera liwiro la mota, yomwe imayang'anira liwiro la mota posintha mayendedwe a siginecha ya PWM. Pamene ntchito yozungulira ya chizindikiro cha PWM ikuwonjezeka, mphamvu yamagetsi yamoto idzawonjezekanso, motero imawonjezera liwiro la galimoto; kumbali ina, pamene ntchito yozungulira chizindikiro cha PWM ikucheperachepera, kuthamanga kwa injini kudzachepanso. Njirayi imatha kukwaniritsa kuwongolera mwachangu ndipo ndiyoyenera ma motors opanda brushless DC amphamvu zosiyanasiyana.

3. Sensor ndemanga liwiro lamulo
Ma motors a Brushless DC nthawi zambiri amakhala ndi masensa a Hall kapena ma encoder. Kudzera mu ndemanga ya sensa ya liwiro la mota ndi chidziwitso cha malo, kuwongolera liwiro lotsekeka kumatha kuchitika. Kuwongolera liwiro lotsekeka kumatha kupititsa patsogolo kukhazikika komanso kulondola kwagalimoto, ndipo ndi koyenera nthawi zina zomwe zimafunikira kuthamanga kwambiri, monga zida zamakina ndi makina opangira makina.

4. Panopa ndemanga liwiro malamulo
Lamulo laposachedwa la liwiro la mayankho ndi njira yoyendetsera liwiro yotengera mphamvu yamoto, yomwe imayang'anira kuthamanga kwagalimoto poyang'anira kuchuluka kwa magalimoto. Pamene katundu wa galimoto ukuwonjezeka, panopa adzawonjezekanso. Panthawiyi, liwiro lokhazikika la galimoto likhoza kusungidwa powonjezera magetsi kapena kusintha kayendetsedwe ka ntchito ya chizindikiro cha PWM. Njirayi ndi yoyenera nthawi zomwe kuchuluka kwa magalimoto kumasintha kwambiri ndipo kumatha kukwaniritsa magwiridwe antchito amphamvu.

5. Sensorless magnetic field positioning and speed regulation
Kuwongolera kuthamanga kwa maginito opanda mphamvu ndiukadaulo wotsogola wothamanga womwe umagwiritsa ntchito chowongolera zamagetsi mkati mwa mota kuwunika ndikuwongolera mphamvu yamaginito yagalimoto munthawi yeniyeni kuti ikwaniritse kuthamanga kwagalimoto. Njirayi sikutanthauza masensa akunja, imathandizira kapangidwe kake kagalimoto, imapangitsa kudalirika komanso kukhazikika, ndipo ndiyoyenera munthawi yomwe kuchuluka kwake ndi kulemera kwagalimoto kumakhala kwakukulu.

M'machitidwe othandiza, njira zingapo zoyendetsera liwiro nthawi zambiri zimaphatikizidwa kuti zikwaniritse zowongolera zokhazikika komanso zokhazikika zamagalimoto. Kuphatikiza apo, njira yoyenera yoyendetsera liwiro imatha kusankhidwa malinga ndi ntchito ndi zofunikira. Ukadaulo wowongolera kuthamanga kwa ma brushless DC motors ukukulirakulira ndikutukuka. M'tsogolomu, njira zatsopano zoyendetsera liwiro zidzawoneka kuti zikwaniritse zosowa zamagalimoto m'magawo osiyanasiyana.
