ABSTRACT A vending machine control with an improved product delivery motor home circuit is described. A modulated DC power supply which may be very cost effectively designed supplies power to one or more DC product delivery motors in a vending machine. Each product delivery motor has an associated switch which passes pulses, resulting from the modulation of the power supply, when the delivery motor is in its home position. A simple motor home detection circuit detects these pulses, and preferably a microprocessor control circuit connected to the detection circuit determines that a home condition exists.
