Abstract
A drive system for a vending or other dispensing machine includes an electronic switch and an electric motor configured to actuate dispensing coils or other dispensing technologies to dispense instances of products. The drive system minimizes the risk of sparking and igniting propane or other volatile refrigerants or other volatile chemicals or materials used in or near the machine. The electronic switch may be a Hall effect switch, and the electric motor may be a brushless DC electric motor. A homing circuit is connected to the drive system to control/monitor actuation of the dispensing mechanism. A wiring harness connects the electronic switch to the electric motor, and may include a connector which can be set to allow the electric motor to operate in a clockwise direction or in a counterclockwise direction.
