Solenoid for pinball machine

Types of Solenoid for Pinball Machines

A solenoid for pinball machine is an electromagnetic device that generates a magnetic force to push or pull a metal rod or plunger, creating mechanical movement.

The following are the main types of solenoids found in pinball machines:

• Electromagnetic Solenoids

  Electromagnetic solenoids are the most common type of solenoids in pinball machines. They consist of a coil of wire wrapped around a metal core. When an electric current passes through the wire, it generates a magnetic field that pulls the metal rod towards the coil. This creates a mechanical movement that activates various parts of the pinball machine, such as the flippers, pop bumpers, and relays.

• DC Solenoids

  DC solenoids use direct current (DC) power supply to operate. They are designed to work with low-voltage DC power systems, typically ranging from 6 to 24 volts. When the DC power is applied, the solenoid coil generates a magnetic field, causing the armature to move. DC solenoids are known for their fast and precise movements, making them suitable for applications where speed and accuracy are crucial. They are commonly used in pinball machines for tasks such as ejecting balls from the shooter lane, activating the locking mechanisms of ball trays, and triggering mechanical animations.

• AC Solenoids

  AC solenoids use alternating current (AC) power supply to operate. They are designed to work with higher voltage AC power systems, typically ranging from 50 to 100 volts. When the AC power is applied, the solenoid coil generates a magnetic field, causing the armature to move. AC solenoids are known for their strong and powerful movements, making them suitable for applications where heavy loads need to be moved. They are commonly used in pinball machines for tasks such as activating flippers, pop bumpers, and mechanical playfield features.

• Pull-in Solenoids

  Pull-in solenoids are designed to pull objects towards them when activated. They require a significant amount of current to generate enough magnetic force to overcome the resistance and pull the armature. Once the armature is pulled in, it may require less current to keep it in the activated position.

• Push-in Solenoids

  Push-in solenoids, on the other hand, push objects away from them when activated. They are less common but can be found in specific applications where pushing action is required.

• Dual-action Solenoids

  These solenoids can both pull and push the armature. They have two coils: one for pulling and another for pushing. Dual-action solenoids are more complex and are used in applications that require both pulling and pushing actions.

Scenarios of Solenoid for Pinball Machines

Solenoids for pinball machines are used for numerous purposes, including:

• Game Control

  Solenoids are critical to game control because they power the flippers, pop bumpers, and other playfield mechanisms that create the game's action and excitement. They enable the player to interact with the game and influence its outcome by providing a strong and precise means of controlling these components.

• Mechanical Movement

  Solenoids are used to move mechanical parts such as the pinball shooter, the ball lock mechanisms, and the ball return systems. For example, the solenoid that drives the pinball shooter assembly pushes the rod forward to launch the pinball at the start of the game, and solenoids lock the balls in play when they are captured by a ball mechanism.

• Scoring and Reward Systems

  Solenoids are used in scoring and reward systems to create physical rewards for the player, such as the tilting mechanism that causes the machine to "tilt" and award points when the player shakes the machine too hard. Additionally, solenoids are used to activate the coin mechanism and the payout mechanism when the player is awarded free games or tokens.

• Sound and Light Effects

  Solenoids create exciting game sounds and light effects by powering the many light-up parts of the pinball machine, including the playfield and the backbox. The solenoids ensure that the game remains visually appealing and engaging by providing a strong and precise means of controlling these components.

• Interactive Features

  Pinball machines include interactive features powered by solenoids, such as moving targets, ramps, and the "gimmicks" unique to different machines. For example, the "Guitar Hero" pinball machine features a playable guitar that players can strum, and solenoids are used to create the vibration effect to enhance the game's interactivity and entertainment.

• Maintenance and Reliability

  Most pinball machines use solenoids because they are cost-effective and reliable. However, proper maintenance is required to keep the solenoids functioning, as dirt, dust, or wear can cause them to malfunction. Regular cleaning and inspection can ensure the solenoid mechanisms operate smoothly and the pinball machine remains in good working condition.

How to choose solenoids for pinball machines

To help customers choose the right solenoids, business owners can provide the following information:

• Identification

  To get the right replacement solenoid, customers will need to know the model and make of the pinball machine. They will also need to know the specific name of the pinball solenoid that needs replacing. They can find this information on the pinball machine manual. If the manual is not available, customers can contact the manufacturer for more information.

• Solenoid Specifications

  Once they have identified the pinball machine model and the faulty solenoid, customers will need to check the solenoid specifications. They will need to know the voltage rating, resistance, and wattage. This information will help them get a compatible replacement solenoid.

• Type of Solenoids

  As mentioned earlier, there are two main types of solenoids used on pinball machines, electromagnetic and EOS switches. It is important to understand the difference between the two types and where they are used in a pinball machine to get the right replacement solenoid.

  If the solenoids are failing in pinball machines frequently, customers will need to test and troubleshoot to determine the cause. This can include checking the wiring, fuses, and connections. They should also check if the pinball machine is receiving the correct voltage. If they are unsure of how to do this, they should get help from a technician.

Functions, Features, and Design of Solenoid for Pinball Machines

Solenoids for pinball machines have several important functions, features, and designs that are crucial to the performance of the pinball machine and the gameplay. Here are some of them:

Functions

• Electromagnetic Force: The main function of a solenoid is to produce an electromagnetic force when activated to move a metal rod (plunger) or arm (shooter). This force is used to create the mechanical movement needed to make the pinball machine parts move.
• Game Interaction: Solenoids also serve the purpose of making the game more interesting by providing the necessary push and pull actions to the parts of the game that need to be interacted with by the player. For instance, the flippers and the pinball shooter are designed to respond to player actions with the right amount of force and speed, ensuring that the game remains challenging and fun.

Features

• Durability: Solenoids are built to last long because they endure a lot of wear and tear during their lifetime. They are made from materials that can withstand repeated use and do not easily break down or wear out.
• Speed: Solenoids operate at high speed, producing the required action immediately when activated. This is important for maintaining the game's pace and keeping it enjoyable for players.
• Adjustable Force: Most solenoids have adjustable force output, which can be customized according to the requirements of the specific pinball machine. This means that the strength of the solenoid's magnetic field and the resulting force on the plunger or arm can be tailored to suit different machines and gameplay requirements.

Design

• Plunger Mechanism: Most solenoids use a plunger mechanism where a metal rod or plunger is pushed or pulled by the electromagnetic force generated by the solenoid. The metal rod or plunger moves through a coil, and the electromagnetic force generated is enough to push or pull the rod or plunger, causing the action required.
• Coil and Core Design: The coil and core design of a solenoid is an important aspect that determines its efficiency. The coil is made from copper wire, and the core is usually made from ferromagnetic materials like iron. This combination ensures that the solenoid generates a strong enough magnetic field to actuate the mechanism.
• Mounting and Integration: Solenoids are usually easy to install and integrate into a pinball machine. They are designed with standard mounting points and connections, making it easy to connect the solenoid to the machine's electrical and mechanical systems.

Q&A

Q1. What is the function of a solenoid in a pinball machine?

A1. The solenoid's role in a pinball machine is to generate mechanical energy by means of electromagnetism. When the pinball machine is powered on, the solenoid is energized, causing an electric current to flow through its coil. This electric current generates a magnetic field that pulls on a metal rod or armature connected to the solenoid. The magnetic field is strong enough to pull the armature towards the coil, creating an audible clicking sound as the solenoid fires. This action causes the solenoid to fire again and again in quick succession. The magnetic field attracts the armature, and the magnetic force is strong enough to pull the armature towards the coil. The process is repeated again and again, forming a rhythmic motion that causes the pinball machine to function. The pinball machine uses solenoids to power flippers, pop bumpers, and the pinball machine's mechanical scoring system.

Q2. What are the common problems with solenoids in pinball machines?

A2. Some common problems with solenoids in pinball machines include overheating, rusting, and mechanical jamming. Mechanical jamming occurs when dust, dirt, or debris accumulates on the armature or mechanism of the solenoid. This accumulation prevents the armature from moving freely, causing the solenoid to fail. Lubricating the mechanism and cleaning the affected parts usually remedy this issue. Overheating occurs when the solenoid is activated for a long period of time. This can cause damage to the coil wire and burn the solenoid. Solenoid coils can develop rust on their contacts, which can cause pinball machine solenoids to fail. Rusted contacts can hinder the flow of electrical current. Cleaning the contacts usually resolves this issue.

Q3. How can businesses tell if a solenoid is malfunctioning?

A3. There are several ways to tell if a solenoid is malfunctioning. If the solenoid is not activating or making any noise, it may be faulty or may not be receiving any power. If the solenoid is too hot to touch, it may be overheated. In some cases, the solenoid may activate but with inconsistent performance. The solenoid may fire intermittently or with a delay.
