So I am working on a project to test turbine blades under water. I want to be able to limit the speed of the blade using a DC motor as a generator. The blade only rotates at about 25 RPM so I'll need to use some type of gear box to to increase the speed of the input shaft of the motor(this has been hard since it needs to be small and require low torque to turn). I have been looking at brushless motors because they're very easy to turn, specifically airplane motors. Like the motor below

So next I am trying to figure out how to limit the speed of the motor. I have looked at ESC for airplanes but I am not sure if they work with a generator. I have also been wondering if there is a way to do this with a potentiometer? Any help any one could provide would be greatly appreciated.
