Re: Gearbox -physics related question
Also, I hadn't thought enough about your theory above, and no it is not actually true. Lightening the gear would not speed up the output.

The limiting factor in the speed of the system is the max RPM of the motor which is a result of motor design. The CIM won't spin any faster than ~5200 RPM or so even if there is no pinion gear or drive train or anything.

When I calculated the time above I was using your equation F = m*a. This relates to a force, a mass, and an acceleration. acceleration is only applicable to speed when introduce time. The reason that the motor won't spin the gear faster is because as the output RPM of the motor increases the torque decreases to 0 at the max RPM of the motor.

Again, hope it helps
