One mighty flywheel! Under some assumptions¹, I would say the largest roller takes about 6 seconds to spin up to full speed! Am I correct in my assumptions?


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.
