SUMMARY

The discussion centers on calculating torque for a spinning wheel system used to accelerate a foam ball. The user is utilizing a motor with specified RPM and torque, connected via a pulley to a sprocket and a shaft leading to the wheel. The primary formula referenced is T = F * d, but the user expresses uncertainty about torque variation across the system. The focus is on achieving the desired RPM for the wheel to launch the foam ball effectively, emphasizing the importance of gearing over raw torque.

PREREQUISITES
  • Understanding of torque calculations, specifically T = F * d
  • Familiarity with pulley and sprocket systems
  • Knowledge of RPM and its impact on rotational speed
  • Basic principles of momentum in mechanical systems
NEXT STEPS
  • Research gear ratios and their effect on RPM in mechanical systems
  • Explore torque transmission in pulley systems
  • Learn about the relationship between torque, force, and distance in practical applications
  • Investigate methods for calculating momentum in rotating systems
USEFUL FOR

Engineers, hobbyists, and students involved in mechanical design, particularly those working with motor-driven systems and torque calculations for rotational applications.

Hi,
For a project, I'm using spinning wheels to accelerate a foam ball. I know the output motor stats (rpm), torque, etc. It's connected by a pulley to a sprocket, which is then connected by a shaft to the spinning wheel. I'm wondering, how would I do the calcs from the motor to the spinning wheel? It's pretty urgent, so any help is appreciated.
The formula's I'[ve tried are T = F * d, but I'm not sure how the torque varies across the system.
 
Physics news on Phys.org
As long as there's some minimal amount of torque sufficient to get the wheel up to speed in a reasonable time, it doesn't matter. The momentum of the entire system, will be more of a factor than the torque from the motor when launching a foam ball. The main issue will be to gear the system so the wheel spins at the rpm you want to produce the speed you want.

You mention wheels, so I assume this is two sets of motor, pulley, wheel?

No, it's two wheels on one axle, but I can adjust that...let's assume 1 for now. Thanks!
