I am going to use some sort of “dynamo” or electric generator component to generate electricity from the flowing drilling fluid. However, the effect of the magnet rotating within an electrical coil creates a “torque” or resistance to the motion of the magnet when current is drawn from the coil. This resistance or counter torque will affect the drilling, so I need to calculate the maximum counter torque that we would generate in this system. The information available to me at the moment is that I would need about 1000 W of power and the generation voltage at the generator is roughly 20-120 V. You may assume the drill bit (or mud motor and magnet in the electrical generator) is rotating at 60 Hz. For all other parameters, you may pick reasonable values.
