Abstract
A fan and a motor are provided. The fan or the motor includes a shaft seat disposed on a frame, a rotor, and a stopping assembly. The rotor is disposed on the shaft seat and includes a hub and a rotation shaft. The hub has a first locking mechanism adjacent to its peripheral surface, and the rotor is connected to the shaft seat via the rotation shaft. The stopping assembly corresponds to the rotor, and includes a second locking mechanism facing the first mechanism. When the rotor smoothly rotates, the first locking mechanism is separated from the second locking mechanism. When the rotor rotates in reverse, the stopping assembly moves along a first direction, and the first and second locking mechanisms contact each other. When the first locking mechanism is affixed to the second locking mechanism, the rotor stops rotating.
