Hi all,
I just bought an MM3 grain mill and from reading these threads, I know I need a motor running around 150-250 RPM and with high torque (40 in-lb or more). Everyone was using models from surpluscenter.com but they are all out, so I've been scouring ebay for other options.
I found this RAE 90V DC motor at 226 RPM, and this RAE motor at 120 RPM. Both seem to fit the bill and cost around $45 shipped, but require another $35 voltage supply and about $10 in parts to connect to the mill.
On the other hand a lot of people have suggested using this low-speed drill from harbor freight. It is cheaper but I'm concerned about the net effect on torque of slowing the motor down to about half its max RPMs and also of using a drill versus a dedicated and fixed/mounted motor.
Anyone with experience in motorizing mills want to weigh in on this?
Thanks so much!!!
