My motor came with a slot on the shaft, and a magnet that fits neatly into the slot, as well as two screws that I assume go into the end of the pulley(motor gear) to help affix it to the shaft. Is this correct? The magnet fits into the slot, but is slightly smaller than the slot so it can move toward the motor, or toward the end of the shaft, is this for pulley alignment? The pulley itself has a slot that allows it to fit over the magnet very tightly onto the shaft.
Sorry for newb questions, but I want to get this right.
