The present disclosure discloses an outer rotor motor and an unmanned aerial vehicle apparatus. The outer rotor motor includes a rotor assembly and a stator assembly. The rotor assembly includes a plurality of permanent magnet rotor elements. The stator assembly includes a stator yoke and a plurality of stator teeth disposed in a circumferential direction of the stator yoke. An air gap is used to separate the rotor assembly and the stator assembly with a gap and in an air gap between an outer arc surface of the stator tooth facing the air gap and an inner arc surface of the permanent magnet rotor element facing the air gap. A gap of a middle section of the air gap is less than gaps of two ends of the air gap.
