It is direct driven. The reason we went with this was because we had success with a similar design in 2006.

¹ - Dual RS775-18 motors directly coupled to the solid aluminum roller, approximately 100 mm wide and 100 mm in diameter with an 85 mm radius, giving a moment of inertia around its rotation axis of ~1067746.85 g-mm². Negligible frictional losses.

Very close, around 7 seconds was where we thought, but while its ramping up, we have plans to occupy the time.

The speed may be slightly overkill, maybe 2 seconds for all three balls but that's just me.

Slow motion video had it 1.5 secs, but its a rough estimate. Again its not a final interval we want, it was just something that happened during testing.
For those asking about the rollers, they are custom made on a lathe.
