As one of you said " A standard AC motor doesn't produce AC when you
turn it"
according to the theory, this acts as a generator. ain't it ?
so it must produce some voltage.
If by "standard AC motor" you are referring to a squirrel gage motor,
it does not necessary start to produce electricity, when you turn it.
It usually requires three capacitors between the phases to produce a
reactive load, before it generates some initial voltage.
Alternatively, installing a small permanent magnet (from the
refrigerator door :-) on the rotor will help the startup condition. On
a squirrel gage motor/generator, you should compensate for the slip,
if you need accurate measurements.
I would suggest using a bicycle dynamo to generate a signal frequency
proportional to the speed of rotation. The dynamo has some environment
protection, starts up without a problem and is a synchronous with the
rotation speed.
