Mitundu yama mota opanda coreless

Kupanga

1. Permanent maginito DC galimoto:

Zimapangidwa ndi mitengo ya stator, rotors, brushes, casings, etc.

Mizati ya stator imapangidwa ndi maginito okhazikika (chitsulo chokhazikika cha maginito), opangidwa ndi ferrite, alnico, neodymium iron boron ndi zipangizo zina. Malinga ndi mawonekedwe ake, amatha kugawidwa m'mitundu ingapo monga mtundu wa cylindrical ndi mtundu wa matailosi.

Rotor nthawi zambiri imapangidwa ndi mapepala achitsulo a silicon, ndipo waya wa enameled amavulazidwa pakati pa mipata iwiri ya rotor core (pali mapiringiro atatu pamipata itatu), ndipo zolumikizirazo zimalumikizidwa motsatana pamapepala achitsulo a commutator.

Burashi ndi gawo conductive kuti zikugwirizana magetsi ndi mafunde ozungulira, ndipo ali ndi makhalidwe awiri madutsidwe ndi kuvala kukana. Maburashi a maginito okhazikika amagetsi amagwiritsa ntchito mapepala achitsulo amuna kapena akazi okhaokha kapena maburashi achitsulo a graphite, ndi maburashi a electrochemical graphite.

2. Brushless DC mota:

Zimapangidwa ndi maginito okhazikika a maginito, ma stator angapo omangika, sensor yamalo ndi zina zotero. Galimoto ya brushless DC imadziwika kuti ndi yopanda brush, ndipo imagwiritsa ntchito zida zosinthira semiconductor (monga zinthu za Hall) kuti zizindikire kusintha kwamagetsi, ndiye kuti, zida zosinthira zamagetsi zimagwiritsidwa ntchito m'malo mwa ma commutators ndi maburashi. Lili ndi ubwino wodalirika kwambiri, palibe phokoso loyendetsa, komanso phokoso lochepa la makina.

Sensor yamalo imasinthira mafunde a stator motsatira dongosolo linalake malinga ndi kusintha kwa malo a rotor (ndiko kuti, imazindikira malo a rotor maginito pole poyerekezera ndi mafunde a stator, ndikupanga chizindikiro chomveka pamalo otsimikizika. , yomwe imakonzedwa ndi chigawo chosinthira ma siginecha kenako ndikuchotsa mphamvu yosinthira mphamvu, ndikusintha mafunde apano molingana ndi ubale wina wamalingaliro).
