    Motor Rpm Spin
AI Thread 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 'Turbocharging carbureted petrol 2 stroke engines'

Hi everyone, online I ve seen some images about 2 stroke carbureted turbo (motorcycle derivation engine). Now.. In the past in this forum some members spoke about turbocharging 2 stroke but not in sufficient detail. The intake and the exhaust are open at the same time and there are no valves like a 4 stroke. But if you search online you can find carbureted 2stroke turbo sled or the Am6 turbo. The question is: Is really possible turbocharge a 2 stroke carburated(NOT EFI)petrol engine and...

Thread 'HP Required to move a robot 10meters at 1.5m/sec'

I need some assistance with calculating hp requirements for moving a load. - The 4000lb load is resting on ball bearing rails so friction is effectively zero and will be covered by my added power contingencies. Load: 4000lbs Distance to travel: 10 meters. Time to Travel: 7.5 seconds Need to accelerate the load from a stop to a nominal speed then decelerate coming to a stop. My power delivery method will be a gearmotor driving a gear rack. - I suspect the pinion gear to be about 3-4in in...

Thread 'Calculate minimum RPM to self-balance a CMG on two legs'

Thread 'Calculate minimum RPM to self-balance a CMG on two legs'

Here is a photo of a rough drawing of my apparatus that I have built many times and works. I would like to have a formula to give me the RPM necessary for the gyroscope to balance itself on the two legs (screws). I asked Claude to give me a formula and it gave me the following: Let me calculate the required RPM foreffective stabilization. I'll use the principles of gyroscopicprecession and the moment of inertia. First, let's calculate the keyparameters: 1. Moment of inertia of...
