Anti cogging idea ?

[helicoil]

 just a basic idea, if this wheel is powered by a motor, and the smaller wheels in the pic are generators, does the larger wheel feel the effect of cogging ?

the generators have a heavy weight that always sit at the bottom during rotation of the larger wheel with a much greater weight than the cogging force.

I think cogging should be negligibly low but the big wheel's rotational speed cannot be too high (max a few hundred RPM).
For generators the ones designed for wind generators could serve fine.

However you have to use brushes to access to the generators output power.

Question is whether the generators are able to provide a resulting output power that covers at least the power needed for the big wheel's rotation? This can be answered only by testing this setup.

Your drawing is not entirely clear, but it should be safe to say that inductors
take time to fill and empty; and so, Gyula's caveat about speed is useful.

Thanks for the reply gyulasun.

Paul-R, sorry about the drawing, only have basic tools.
the basic idea is attaching generators to the wheel (in blue on the pic).The body of the generators are fixed to the wheel,
a weight which is much more heavier than the cogging force is attached to the rotor causing an imbalance on that rotor, but not on the motor driven wheel.
Rpm's would need to be limited else the weights will start to fly outwards, this would stop the spin on all the generators.
  The question is can a motor use less power to drive the wheel than the generators output, and will the drive wheel notice the cogging on each generator.
Im hoping its simply a flywheel, and for each rev many generators produce power, without adding any extra strain except for there weight.

Yes, and your question can be answered only by building a prototype setup.  Do not worry about the big wheel cogging question, it is not that important (I mean it would be small).
For the test, for the generators,  you could use some stepping motors because they can work nicely as generators too. OR some DC motors with magnets, they also can work as generators. Unfortunately the DC motors efficiency at low RPMs are low. (Stepping motors are better in this respect.)  Have you got already thoughts on building such setup?
