It would be easier to reduce the stored potential energy before the device is allowed to run. The rotation speed is a measure of the kinetic energy that has been derived from the initial stored potential energy due to the magnet location above the drum magnets. Move the drum around slowly to ensure that any initial potential energy is reduced and measure the rotation speed that is generated. A true perpetual motion machine will increase speed back to the value seen in the video.
The only tricky concept is that the contraption attached to the device may be some form of speed control that meters out stored energy as required to keep the speed constant. This may be what they are doing, but it is not clear. If they are using some form of speed control, then it would be quite easy to confuse anyone observing the operation of the machine. Enough time and a little friction will always eventually stop the device if it is a scam.

If there is difference in duration how long the motion will last, then it would show clearly that it is indeed perpetual motion machine. Of course this kind of test is only necessary if you do not believe theoretical a priori argument that magnets do not store potential energy, but magnetism is just matter of information. �\Jouni
