It's a machine that transfers power via motion. Standard stuff that follows the rules.
If the magnets have a force of 1kg then a pair of them will push apart with a force of 2kg.
If you can push a metal plate between them and change that 2kg of push by 100% into 2kg of pull then you will need a force of 2kg to move the plate back out of the way again.
Magnetic fields loose strength over distance fairly rapidly.
If you actually build the model you will find that the plate needs to be thick enough to get the full 2kg from the magnets.
If it is thick enough then you will loose the full 2kg push when you move to open space.
You could improve the design by tapering the lead-in & lead-out of the slots. You could reduce the effects of surface friction by fitting non-magnetic roller bearings to the outer edge of the magnet holders and running those on the inner surface of the disc.
You'll also want some sort of linkage to keep the magnets parrallel through the travel to get full efficiency out of them.
I think the biggest problem with construction will be overcoming the friction on the grooves of the drum and that's if you can actually work out how to make it in the first place!
