stepper motor for a chile roaster
Chile addict, as in capsaicin laden chile peppers from New Mexico. I used to rely on commercial roasters, but they are inconsistent and I like high roaster temp for short time so the skins are easy to remove, but the meat of the chile is still crisp (NOT soggy and overcooked). I freeze a ridiculous amount of roasted peppers in one gallon ziploc bags, defrosting ~2 every week (my son is now an addict as well).
I bought a roaster, but the cage rolls too fast, so I am replacing the electric motor (1725rpm) and the inadequate "repurposed" gear reduction hardware with a stepper motor/controller. The parts consist of a power supply (24/48VDC), stepper motor controller, and the stepper motor. In addition, I am waiting for a pulse width modulator with a speed control knob, direction switch. The ancient red step down gear reduce has a bad bearing, and the pulleys are held in place with tension bolt on a flattened surface (shafts) instead of a keyed shaft (MUCH more reliable and lower maintenance). Once I wire the thing up to the PWM and verify variable speed control, I will probably get a planetary reduction gearbox and a pulley to replace the red thing.
