For example, I have an old fan. How do I modify the motor to generate electricity from the wind?
Sell the AC motor on Ebay and buy a generator on Ebay.
perhaps. It relies upon on the rotor. If the rotor is made up of permenant magnets, in simple terms rotating it is going to turn the motor right into a dynamo and create electric powered potential. in spite of if, many autos place self belief in electricity to create magnetic fields around the rotor, so there is going to must be some comments from the output back into the rotor circuit to generate the fields. in spite of if, this potential is going to be responcible for growing to be the output interior the 1st place. for this reason, this may well be an impossible layout, because of the fact it would be in reality a perpetual action gadget. The electricity imparting the rotor coils might must be enter from an independant circuit. perhaps linking a magnet pushed electric powered motor to the rotor of the coil pushed motor might artwork, in spite of if it would be surprisingly inefficient except the device grew to become into balanced precisely in terms of the potential flowing between the coil and the magnet based dynamo. yet another strategies-set may well be to apply image voltaic cells tocontinual the rotor coils. i've got not got any thought of ways effective this may well be, yet i've got self belief it is going to take particularly super sized cells tocontinual the rotor windings. of path one final element to concider is the fact dynamos and image voltaic cells generate direct contemporary. maximum coil pushed rotors function off alternating contemporary. The DC contemporary might must be switched over into AC contemporary at 60 cycles consistent with 2nd at a voltage adequate tocontinual the coils. DC to AC circuits are trouble-free to construct and if one may well be able to generate 60 cycles consistent with 2nd, the form of the coils on the rotor will shield the rest. 60 CPS (cycles/2nd) is a regular layout in means grids, and electric powered autos are designed around this familiar.
Oh man I just Loved jenifers answer - very practical! For the simple reason it is impossible to reasonably convert a single phase induction motor to be a generator of useable electricity ...
