Outer rotor brushless motor ndi mtundu wa axial flow, maginito okhazikika a synchronous, brushless commutation motor. Amapangidwa makamaka ndi rotor yakunja, stator yamkati, maginito okhazikika, makina oyendetsa magetsi ndi mbali zina, chifukwa misa yakunja ya rotor ndi yaying'ono, mphindi ya inertia ndi yaying'ono, liwiro ndilokwera, liwiro la kuyankha liri mofulumira, kotero kachulukidwe mphamvu ndizoposa 25% kuposa injini yamkati ya rotor.
Magalimoto akunja a rotor amagwiritsidwa ntchito pazinthu zosiyanasiyana, kuphatikizapo: magalimoto amagetsi, ma drones, zipangizo zapakhomo, makina opangira mafakitale, ndi ndege. Kuchulukana kwake kwamphamvu komanso kuchita bwino kwambiri kumapangitsa ma rotor akunja kukhala chisankho choyamba m'magawo ambiri, kupereka mphamvu zamphamvu komanso kuchepetsa kugwiritsa ntchito mphamvu.
