My current stir plate is basically a computer fan. The torque isn't bad, as the fan will try to control its own speed (4-wire fan taking a PWM signal for speed), so power isn't automatically reduced when I turn it to low speed--only when it's moving too fast. There must be some kind of feedback in the fan's controller. It is stronger than the cheap stir plate I bought from taobao.
I'd like to step up this idea and make a stir plate strong enough to mix honey at 1-2 RPM. Is there any kind of motor that would be good for that, or would any motor need a gear box?
