Sizing a motor
Sizing a motor
(OP)
Test setup: I need to have a disk, diameter = 1ft, spinning at 955rpm. A normal load of 2866lbs via an aplicator whose diameter is 0.25ft would be applied to the disk surface at 0.25ft from disk center. Ultimately I know I have to calculate the inertia of the system, torque or stalling torque, and the power (hp), however, I do not know generate my formulas for the particular application. How do I size the motor correctly. Any input would be greatly appreciated. Should you need more info, please feel free to contact me. Thanks

On the other hand, if you want to accelerate the 1ft dia disk up to 955 RPM quickly, you'll have to calculate the necessary torque at all points during the ramp-up for the curve that matches your motor type.
If you give some more info on how your application operates, it might be helpful to see which of the two cases are most important.

If it is OK to slow or stall the motor after the load is applied, then you really only need to be concerned with how fast you want to bring the inertial load up to speed. If you've got some time, then a fractional hp motor can do the job. If you need it really quick, then you might need even more than the 20 hp (depending on the type of motor and the inertia of your disk).
What type of motor are you planning to use (DC, AC, etc.)? If you can describe the application a little more, you can usually get a lot of feedback in these forums (sometimes more than you want).

Can it sustain 16.5 rps (with it being acted on by 716.5 lb-ft) without coming apart?
