Could you refine your question. Do you want to know what parameters are necessary to specify what is generated? Even the term generate electricity is not very well defined.
It depends entirely on the design of dynamo or generator, and the source of power driving them. If the source is weak then the electricity won't be very stable.
As you may have noticed, there are a lot of designs out there.
You would still need to know RPM and stator excitement level to get a direct relation.
The number of windings and the number of turns in each winding relate to the voltage created, and the current is related to the number of times the magnet is passed by the coil, and if its not a permanent magnet motor, it will also depend on the voltage and current in the stator.
