SUMMARY

This discussion focuses on calculating the torque and RPM requirements for an electrical motor based on a specific application involving a shaft with a 2-inch diameter and 6-foot length. The motor must lift a weight of 10 pounds over a distance of 7 feet in 6 seconds. Key formulas for these calculations include the torque formula (Torque = Force x Distance) and the RPM calculation based on the desired lift time. Participants emphasize the importance of demonstrating an initial approach to problem-solving in engineering contexts.

PREREQUISITES
  • Understanding of basic physics principles, particularly force and torque.
  • Familiarity with electrical motor specifications and performance metrics.
  • Knowledge of unit conversions, especially between imperial and metric systems.
  • Basic mathematical skills for applying formulas and calculations.
NEXT STEPS
  • Research the formula for calculating torque in electrical motors.
  • Learn how to convert between different units of measurement, particularly for force and distance.
  • Explore the relationship between RPM, torque, and power in motor applications.
  • Investigate practical examples of lifting mechanisms and their motor requirements.
USEFUL FOR

Engineers, mechanical designers, and students studying mechanical engineering or electrical motor applications will benefit from this discussion, particularly those involved in designing lifting systems or calculating motor specifications.

Hello!

How do you calculate or determine Newton meter force requirement and rpm's for an electrical motor in the following example:

A device that utilizes a shaft that is 2 inches in diameter and 6 feet length. It needs to be able to lift 10 pounds and distance of 7 feet in 6 seconds. I need to know the formulas to make these calculations and the requirements needed for this application?

Thanks in advance for any assistance!

Mr. Nice Guy.

You are going to have to show your own approach first...

Edit -- And this should also be in the homework help section of the forum.
