ABSTRACT:
A self-adjusting motor positioning system comprises a motor including a shaft extending therefrom, a disc coupled to the motor shaft and having at least first and second notches, rotating apparatus coupled to the motor shaft whereby the rotating apparatus is intermittently driven by the motor, a sensor adjacent the disc for detecting the first and second notches, and a control processor coupled to the sensor and the motor for receiving detection signals from the sensor and for turning the motor on and off. The control processor includes memory for storing a time delay count representing a time delay for the control processor to turn off the motor after the second notch is detected by the sensor. The rotating apparatus includes a starting position from which the rotating apparatus begins. The first notch in the disc corresponds to the starting position of the rotating apparatus. The control processor turns the motor off when the time delay expires after the sensor detects the second notch. The sensor senses for the first notch as the motor coasts to a stop, and the control processor adjusts the time delay count if the first notch is not detected when the disc is at a complete stop.
