Abstract

The present invention is a fan having rotation sensing, comprising a casing, a motor disposed within the casing, a rotation sensing unit, and a control unit, the rotation sensing unit detecting a first rotation of the casing and outputting a first sensing signal, the control unit having a controller electrically coupled to the rotation sensing unit and the motor, the controller receiving the first sensing signal according thereto to control the motor to perform a first operation mode. Through this design, an operation mode of the fan can be adjusted according to the rotation of the fan in the present invention.
