SUMMARY

When selecting a motor capable of spinning at 3500+ rpm while supporting a weight of 200 lbs, key attributes to consider include torque, bearing loads, and the orientation of the shaft (vertical or horizontal). The discussion emphasizes the importance of defining specific speed tolerances, such as whether a 3450 rpm AC motor is acceptable. Additionally, factors like the moment of inertia, balance of the load, and desired bearing lifespan are critical in making an informed decision.

PREREQUISITES
  • Understanding of motor specifications, including rpm and torque
  • Knowledge of bearing loads and their implications on motor selection
  • Familiarity with load balancing concepts (static and dynamic)
  • Basic principles of mechanical engineering related to motor applications
NEXT STEPS
  • Research AC motor specifications and performance characteristics
  • Learn about torque calculations for motors under load
  • Investigate bearing types and their load capacities
  • Explore the effects of moment of inertia on motor performance
USEFUL FOR

Mechanical engineers, motor selection specialists, and anyone involved in designing systems requiring high-speed motors with significant load-bearing capabilities.

Hi, i need help figuring out what to look for in a motor given certain specifications. If I am browsing for a motor that is able to spin at 3500+ rpm while holding 200 lbs. of weight, what attributes/values do i need to pay attention to?

You need to say exactly what your speed will be and what tolerance you can live with. For example, would a 3450 rpm ac motor do?

The 200 lb weight presents two issues: torque and bearing loads. Will the shaft be vertical or horizontal? Will the shaft be supported? Will the load be overhung? What will be the moment of inertia of the load? Will the load be statically balanced? Dynamically balanced? How long do you want the bearings to last? How much money do you want to spend?
