。Effects of the Invention As described above, according to the present invention, the flywheel is provided with a recessed groove to provide the effect of an oil sump, thereby making it possible to maintain the rotation of the rotating body even when the rotating center line of the rotating shaft is horizontal. It is possible to prevent oil from flowing into the braking mechanism, that is, the mechanical brake contact surface, and as a result, it is possible to prevent changes in the rotational load of the rotating body. Furthermore, changes in stopping accuracy during intermittent rotation can also be prevented. When the broken motor stops, oil flows from the recessed groove to the shaft, which has great effects such as preventing the bearing from running out of oil.
