Abstract
A rotating motor and a fan are provided. In the rotating motor, by arranging a first bearing seat, a second bearing seat, and a plurality of support rods to form the supporting frame, the coaxiality between the first bearing seat and the second bearing seat can be ensured to reduce the accumulated tolerance of assembly. In addition, the motor has a stator having stator teeth. The inner diameter of the inner circular hole of the stator teeth is disposed to be larger than the outer diameter of the second bearing seat.
