......the idea of using eddy currents as a brake mechanism. While I was googling up explanations of the effect I came across some interesting stuff. It seems that diesel-electric locomotives have been using eddy current technology to brake their wheels for quite some time now. Imagine the forces involved!As I consider it one idea that does to occur to me, and I'm not sure it is correct, is that the eddy brake might offer a means of smoothing/filtering out at least some of the cogging effect off the motor.
While the motor is driving the large pulley in one direction there is a measured amount of force applied to that same pulley in the opposite direction, pulling, restraining the pulley in a smooth and even manner. Thus mitigating some of the pulsing off the motor.
Also the driving wheels, the pinion, the idler, the driven platter form a kind of gear train who's rotational inertia will produce a flywheel effect to absorb any remaining cogging effect off the motor, and produce a smooth "forward only" driving mechanism.
