Oct 19, 2006· Using pulleys i divide by 2 the velocity to 1400 rpm, but the container works at 140 rpms, because there is a reduction of 1/10 (the container spins one time each ten turns of the shafts) in the velocity. The motor has been working for 30 minutes, and works good, and it is not hot ( The ventilator, in this velocity, works )
