  Still not clear, sorry. Don't shy away from writing more 😀 . What setup are you thinking that would lead to generation of power from table fan?

  No i am not shy. If connect some alternator to backside of table fan. it takes load. For that i need solution .

  the torque generated by a table fan motor is not sufficient to power an alternator.
  
  i tried this project once myself.

  Hi, can explain as detail.

  table fan and ceiling fan motors are very low power motors and they are designed with a very low factor of safety, that is to say, that the torque generated by them in Nm is very low and only enough to accelerate the blades which are generally light weight.
  
  the armature of an alternator however requires more torque, than can be provided by any domestic fan motor.
  
  so if you mechanically couple the shafts of the fan motor and alternator, the fan motor will stall, due to the high moment of inertia of the alternator armature,

  Do you mean, make the fan motor work as an alternator, by making the motor rotate with the help of blades absorbing energy from wind blowing outside?
  
  Its an induction motor in most fans. Making induction motor work as a generator is not so easy as with its counterparts with those fan baldes. Induction motors need to be rotated at a speed greater than the rated speed for this to happen. something that is almost impossible with a normal table fan using natural wind as a power source to the prime mover.

  how about manufacturing fan regulators and calling bells. ?
  
  it is quite lucrative nowadays.
