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.

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 (e.g., Fawn-type or AMS-type) 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.

Abstract: A control circuit for a PMDC motor used in an ice delivery apparatus, the circuit including a double pole double throw relay that switches both sides of the circuit and peripheral circuitry connected between a power source and the double pole double throw relay to rectify the power source and power the PMDC motor.

Abstract: A bobbin for an electromagnetic inductive wire coil, to which at least one terminal is attached, has a hollow body with two opposite ends. A side flange is molded integrally to each one of the opposite ends. Each side flange has a plurality of corners and at least one reverse L-shaped rib configuration in at least one corner so that the rib configuration prevents rotation of the bobbin and breaking off of the terminal when a rotational force is applied to the terminal. Another reverse L-shaped rib configuration may be positioned upside down in another corner of each side flange. The reverse L-shaped rib configuration may have a third rib molded integrally thereto to form a reverse C-shaped rib arrangement to confine a rear end of the terminal. This confinement helps to prevent backward movement caused by a head-on force applied to a front end of the terminal.
