I have invented a power unit with very large torque and I want to use it to power electric generators. The problem is I need a electric generator that can produce several megawatts in a horizontal configuration at about 45 rpm. From all my knowledge of generators I believe this can be done. What do you think? Your comments are welcome.
The voltage induced in the windings of an electric generator is a function of the strength of the field and the speed at which the windings are cutting through thismfield. To get into the realm of practicality you need to get your poser unit output up to somewhere between a thousand and six thousand rpm by use of gears or drive belts. AC generators turn around 1800 rpm since that is a multiple of 60 cycles. In DC generators or alternators that are rectified to DC the higher speed the better. There is a lot more to it but that is all you need to know from where you are now.

In wind Generators the Propeller only turns at about 30 rpm but the propeller power goes through a transmission and the Alternator-Generator turns faster so in answer to your Question, Yes it can be done!
I suggest you try to use or rent test equipment if your power unit is compatible to electric generator. By that, you will know if they will both function.
I think you should be able to get good power if the rotor is of a large diameter
so that the edge speed is the same as a smaller rotor edge speed. I would
build it like a play ground go around of about 12 ft dia.
