astarali Posted February 1, 2022 Share Posted February 1, 2022 Hello i am working on a Arduino Project and i want to make some customization on a sneck vending machine. i need some help and i have quastions about vending machines spiral motors(dc). -are these dc motor or servo? -based on my search on internet , there are 12v and 24v with 2 pin - 3 pin - 4pin models of these motors , what are these pins ? coud you explaind about them ?as i know basicly there must be GND VCC NO NC CoM so how 2 pin models works ? how 3 pins models works ? coud you share a diagram of 2pin 3pin and 4 pin models. btw i am software programmer and i am not familier with electronics , maybe my quastion is compleatly wrong.

Vendo Mike Posted February 1, 2022 Share Posted February 1, 2022 There are WAY too many versions of snack machines to answer all of your questions on here. You will need to determine a model to work on a expand from there. Almost all equipment in the field has a wiring diagram in a service manual on their mfg website. You will need a basic understanding of those or hire someone that does in order to make any "redesign". What exactly is your goal? 1 Link to comment Share on other sites More sharing options...
AZVendor Posted February 1, 2022 Share Posted February 1, 2022 (edited) All I can tell you is that any plastic motor is a DC motor. Other than that what the pins do is up to the individual machine/manufacturer and you would need to view their specific wiring diagrams. AP uses 2 pin motors with the polarity keyed. The AP LCM line used 24v motors not used on any of their other machines. AP motors are probably the most plentiful. Stay away from USI motors as there are about 1 billion different ones that they have used. You will notice that I dont mention any other manufacturer or seudo-manufacturer or imported machines. As always, I wonder why you think you need to design your own board/machine from kit parts. The industry doesn't need any new players and the only problem that needs to be fixed is to take the industry back to before Crane bought their competitors out and ruined the machine industry.

astarali Posted February 1, 2022 Author Share Posted February 1, 2022 Hello actualy i have to design my coustom arduino , because my system is compleatly diffrent with normal sneck vending machine i just need to use vending machine dc motors and cabin , there is no need to bill acceptor , coin acceptor , credit card reader , keypad and .... my system is connected to a local sql server database , and users will pay with their point from database . example dc motor pic i need to learn , what are these pins , because there are 2 pin - 3 pin - 4pin models in diffrent models , and my board must be ready for all possible models (motors). as i know basicly there must be GND VCC NO NC CoM , but these are 5 . how 2 pin model wokrs?! what about others!

AZVendor Posted February 1, 2022 Share Posted February 1, 2022 You are obviously not in the US so you are not going to get help from us. The motor in your photo is what we would call an import here in the states and that would be considered junk due to no support available to US operators. You are on your own on this.

AZVendor Posted February 1, 2022 Share Posted February 1, 2022 Call it what you want but machines in the US just use manufacturer-supplied logic boards. They might be made by someone else (Coinco and Mars used to make a lot of them) but there is no special technology like "quanntum computing."

You should ask a manufacturer these questions. 1 Link to comment Share on other sites More sharing options...

Best The vast majority of the members here have no idea what you are talking about. We are operators and technicians, not engineers or manufactures. Please be understanding of that fact. However, I have dabbled in amateur electronics as a hobbyist, and will attempt to assist as best as possible. *puts nerd hat on* From your questions, you really are a software guy only. There are some major issues with your plan. A DC motor works when you apply power to it. You apply power, it starts spinning. Reverse it, it starts spinning the other direction. Note that vending machine motors usually have additional circuitry installed, and reversing may damage the motor. A 2 pin motor is the base. One pin is power, the other is ground. Apply power and it spins as long as there is power. For the 5 pin pinout you describe, GND VCC NO NC CoM, GND and VCC are likely the 2 pins that make the motor spin. NO NC and COM typically describe the bins of a switch. In the context of a vending machine motor assembly, this switch is likely a microswitch that is activated by a cam on the motor, which allows the machine to know when the motor and spiral is at a certain position. Now, the idea of making your board compatible with all sorts of motors seems nice, but is not practical. There are so many variations among generations and manufactures that it would be very hard to cover them all. Even the companies that sell aftermarket replacement boards sell different versions depending on machine. Your best bet would be to find a good machine, preferably a popular one that has a good track record of reliability, with plenty of machines and spare parts available, and settle on that and design around that machine. Here in the US, a good candidate for such a project would be an AP 7600, AP LCM, or National 159. Also, it does appear that the Arduino will not be suitable for your project. There are not enough pins and SQL will be difficult to get running on Arduino. Based on your lack of understanding of basic electronic hardware, designing a custom Arduino to overcome these issues will be an extremely challenging or even unfeasible task for you. Personally, if I were to do such a project, I would start with a Raspberry Pi, and keep the stock vending control board. I would study the wiring diagram of the machine and connect the vending machine keypad wires to the Raspberry Pi. In this way, you can replace the keypad with the Pi. Set the vending machine to free vend, and use the Pi to simulate keypresses. For instance, if the customer selects chips in selection A3, the Pi would get that request and then connect the pins that makes the machine think that the A and 3 buttons were pressed. The machine control board will then handle the motor control, and vend the product. This allows you to have a simplified machine interface and not have to worry about handing power or motors. 4 Link to comment Share on other sites More sharing options...
tblake05 Posted February 2, 2022 Share Posted February 2, 2022 "My smartass hat on" LOL Why not just buy a motor and dissect it? From there with a multimeter you should be able to figure out what pins do what. 1 Link to comment Share on other sites More sharing options...

NYCandyMaN Posted February 25, 2022 Share Posted February 25, 2022 trial and error will usually work for this situation, i gotta get my 2 cents in there Link to comment Share on other sites More sharing options...
Dvending Posted March 2, 2022 Share Posted March 2, 2022 Design software for a PLC that will be able to read the user input and convert it to a timed relay output. The output would then turn the motor to vend the product. You would only need the positive and negative pins of the motor, therefore eliminating the need for COMM, NO and NC pins. I’ve wired up large HVAC systems with this type of design, so it is possible. Good luck. Link to comment Share on other sites More sharing options...
