I-Outer rotor brushless motor iwuhlobo lokugeleza kwe-axial, i-synchronous kazibuthe unomphela, i-brushless commutation motor. Ikakhulukazi yakhiwe i-rotor yangaphandle, i-stator yangaphakathi, i-magnet unomphela, i-commutator ye-electronic nezinye izingxenye, ngoba isisindo sangaphandle se-rotor sincane, isikhathi se-inertia sincane, isivinini siphezulu, isivinini sokuphendula siyashesha, ngakho-ke ukuminyana kwamandla kungaphezu kuka-25% ngaphezu kwe-rotor motor yangaphakathi.
Ama-outer rotor motors asetshenziswa ezinhlobonhlobo zezinhlelo zokusebenza, kufaka phakathi kodwa kungagcini nje: izimoto zikagesi, ama-drones, izinto zasendlini, imishini yezimboni, kanye ne-aerospace. Amandla ayo aphezulu kanye nokusebenza kahle okuphezulu kwenza ama-rotor motors angaphandle abe yisinqumo sokuqala emikhakheni eminingi, ehlinzeka ngamandla okukhipha amandla nokunciphisa ukusetshenziswa kwamandla.
