I have already calculated the torque per S and torque per revolution at the drive pulley & driven pulley. I just thought I might need to integrate the torque per 1/2 revolution in order to get the full amount of work done per screen oscillation. As for calculus, I only mentioned it because I...
Haha... not really. It will either have enough power or it won't. But, I would still like to know the minimum oscillation speed of the sifter basket :). Assuming I found such a motor & got it setup, do you have any idea how I might be able to easily determine the shake speed if I don't have a...
Hi Jim. Thanks for replying to my thread and for your encouraging words!
That is true for static torque, but motor torque is expressed as force*distance/time just like horsepower is expressed as force*distance/time.
Hmm.. I have never seen that equation. How did you derive it?
That is an...
I have a textbook on the subject. I'll look into what it conveys on force system resultants. Maybe that will help. It's been a while since I've used trig, integration, or calculus.. It may be over my head at this point ;)
Thanks for your help.
I think it would be better to describe it this way: In first gear, the smaller (drive) gear transfers engine torque (rotational force) to the relatively larger (1st) gear. The smaller gear rotates much faster than the larger gear. The available torque is transferred across both gears in...
Hello mdjensen22. Thank you for contributing to my thread.
The vacuum motor doesn't have a data label on it. Is there some way that I can determine how many "poles" the motor has?
I energized the motor and it seems to spin up to a constant speed. As my load will change when I add soil...
Hello psparky. Thank you for responding to my posting.
Yes, my AC is 60 Hz. The clothes dryer motor label shows:
HP=0.2
RPM=1725
Therefore, the driven pulley should revolve at 215.625 rpm (+/- some amount due to load & line variations, I guess--although, I don't know how to calculate...
I would like to make an electric motor powered soil sifter for sifting soil/compost, but I'm a bit stumped at the moment. I'd like to use an inexpensive single phase AC motor from a an old vacuum cleaner or a clothes dryer, but I don't know how to determine what size electric motor I would need...
I recently acquired a few things that I'm hoping I can use to build a heater for a small area (10'H x 12'W x 12'L).
Things I current have:
1. 20 gallons of used motor oil.
2. An old 5200 BTU window AC unit. The blower components work, the coils are 'supposedly' good, but the compressor is...
