hi !

I want to build a wind vane from a low friction AC motor which spins
its rotor to the wind. And I am going to convert the frequency of the
AC motor into respective voltage and fed to the ADC to display the
speed on a PC.
Is their any commercially available "Frequency to Voltage converter"
ICs for this kind of applications ?

A one-shot followed by a low-pass filter will convert f to V. But if you
are feeding that to a uC again, it might be easier to just let the uC
measure the frequency directly. In that case you don't need an ADC, less
external components and it's probably more precise.
