Hi Everyone,
I am trying to make a machine a bit like this from my potting wheel to do some art on - ( Click it to 5min 25 seconds)
https://www.youtube.com/watch?v=8h1Ci0nAnI4
But I am failing as at 240 RPM it just doesnt spin fast enough and I cant really modify whats there ( cone drive). It also seems a motor of that size would be way overkill as the canvas I would be painting on wieghs next to nothing.
So I am after something industrial strength, that I will mount in a box like on the video, that can run on and off all day etc.
It doesnt need much torque as aside from the X jig to hold the canvas its only a light framed canvas I would be putting on it.
However it would be bad if I were using it with an audience and all of a sudden it started to smoke and smell and die.
It needs to work at a professional level.
So Ive been told just mounting a variable speed dc motor in a ply box is the best way to go but might be expensive.
I know nothing about electric motors and have no idea what to buy.
A lot of motors say the RPM but Im pretty sure that the actual output at the spindle can vary from this figure?
In any case, I would like it to run at about 60-100 RPM going slow then about 900-1500 RPM going fast.
I would like switches to change the speed.
Can anybody direct me to what I should be looking at?
Secondly - If variable speed is too expensive for me, what should I be looking at for a single speed motor. Or even a three speed motor?.
Something around 900 - 1500 RPM?
I need to be able to poke the spindle through a box and mount a pulley or something on it to weld my frame onto.
Any ideas would be most welcome.
Thank you very much
