From the description of the situation, should be to make an improper fastening screw of stator core and rotor core caused by the death card. Because the electric fan adopts the asynchronous motor stator and rotor clearance is very small, generally less than 0.5mm, the general installation should pay attention to the diagonal fastening screws sequentially tightened, if not the diagonal sequence (but by adjacent order) to tighten the screws easily cause stator and rotor stuck, and cause failure phenomenon the motor does not turn. The issue of "singing" the sound is generated by electromagnetic force between stator and rotor. Check whether the card was in the situation of power of small rotation of the rotor, can feel stuck. Should pay attention to: do not use a hand to drive the wind blade rotation, or in case there is no card dead, it is easy to hurt the finger.
 
When the power is turned off, the rotor can be turned easily and freely, and the electric fan can not rotate, the biggest potential is that the split phase capacitor of the electric fan is damaged. Because the motor of the electric fan are mostly single-phase asynchronous motor to single-phase asynchronous motor starting must be in the words of the two windings of one phase access split capacitor, the current flowing through the two phase windings, bad capacitor, single phase winding can only produce the Mai Zhenci field motor will not start.
