    Motor Rpm Spin
Click For Summary
When selecting a motor capable of spinning at 3500+ rpm while supporting a 200 lb load, key attributes to consider include the required speed tolerance, torque, and bearing loads. The orientation of the shaft—whether vertical or horizontal—affects the motor's design and load distribution. Additional factors include the moment of inertia of the load and whether it is statically or dynamically balanced. The longevity of the bearings and budget constraints are also crucial in the decision-making process. Understanding these specifications will help in finding the right motor for the application.

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?

Thread 'Measuring Deer Antler Volume'

My idea is that I want to use immerse Whitetail Antlers in a fishtank to measure their volumetric displacement (the Boone and Crockett system is the current record measurement standard to place in a juxtaposition with) I would use some sight glass plumbed into the side of the tank to get the change in height so that I can multiply by the tank cross-section. Simple Idea. But... Is there a simple mechanical way to amplify the height in the sight glass to increase measurement precision...
