Cooling tray motor suggestions
kwrcst
Hi all. I?m getting to the point of building my cooling tray and wondered what any of you have used for a motor to stir the beans? I figure 30rpm should be fast enough but I?m open to thoughts. I?m looking at this maybe

30 is too much, imo, commercials are turning in the 10 RPM ballpark.

For up to 1 kg I am using this motor so far:

There are also 68/70 series, similar look, but bigger, with 28/40W rating.
15-20-30 RPM are available, but definitely 30 would turn too fast.

I don't see the reason of DC for this job, you don't need variable speed, and AC save the cost of a power source.

I guess I forgot to mention I already have a 24v set up for the electronics. I went that route because the DC motors were way more affordable than AC. I can get the same motor in 10 rpm if needed

More affordable ? $42 yours vs $17 ...

I meant the drum motor was DC because the AC version was like $200 and the one I got was $60. I wasn?t aware I needed one that slow so yes, I can go cheaper. Just figured I have a 24v power supply onboard and the less cords I have to run the better. I really just wondered what others were using and the speed. I?ll look for something slower now

Thanks
