I think that you should bear in mind that the lateral load spec on the
    spindle is for the spindle and the bearing, not for the innards of the
    motor. 200G's might shatter the permanent magnet of remove it or some
    restrainging device from the spindle. It could also cause glue (which is
    often used to fix the magnet on the axle) to be extruded and make the
    motor permanently eccentric.

The parts of the motor do not experience 200gs.  Only things out at the rim
see that, and the motor sees corosponding FORCES based on the combination of
the Gs and the masses out at 1m radius and 7rps.  Internal issues due to
centrifugal force should all be covered by a max rpm spec, and everything
else IS up to the spindle and bearings.
