There's no pulley on the load. It's a simple guillotine-style door. The motor will have a spindle on it, a cord attached to the spindle which will wind up when the motor is forward energized, which, in turn, raises a flat door in a track. When the motor is reverse energized, the spindle...

Yes, it's a geared motor, sorry! High torque. I'm limited to 12 volts DC, so that's out. I thought it was as simple as increasing the diameter of the shaft (pulley), which would increase the circumference, thereby moving more belt per revolution, effectively increasing the rpm. Thanks! Jack

Hi all, I have a small DC motor which turns at 20 rpm. The shaft diameter is 6mm, giving a circumference of 18.85 mm. What I want to do is get an effective rate of 30 rpm. Can I do this by simply attaching a spool or spindle to the motor output shaft with a larger diameter? If so, would it...
