reaction ring / catch the stick game
Most entertainment machines are not designed for continuous, uninterrupted operation at maximum duty. Components—especially electromagnets—need periodic “rest” to stay within safe operating limits.
This is why your user manual also clearly states that reaction ring machines should not be kept on and in idle mode for long periods of time.
Why cooldown is required
- Electromagnets generate heat
Coils (solenoids, relays, locks, ticket dispensers) convert electrical energy into magnetic fields, but also into heat (I²R losses). Continuous activation raises coil temperature quickly. - Duty cycle limits
Many coils are rated for intermittent use (e.g. 10–50% duty cycle). Running them continuously exceeds their thermal design and leads to overheating. - Insulation breakdown
Excess heat degrades the enamel insulation on windings. This causes shorted turns → reduced magnetic strength → higher current → rapid failure. - Mechanical wear increases with heat
Heat affects springs, plungers, and bearings:- Reduced lubrication effectiveness
- Expansion causing tighter tolerances or sticking
- Faster wear on moving parts
- Power supply stress
Continuous high current draw from coils and motors:- Heats up the PSU
- Causes voltage sag
- Increases ripple and electrical noise affecting logic boards
- Thermal buildup in enclosed cabinets
Arcade cabinets often have limited airflow. Heat accumulates, raising internal temperature for all components (PCBs, displays, wiring). - Other heat-generating parts
Not just electromagnets:- Motors (cranes, wheels, pushers)
- LED drivers and power supplies
- Amplifiers and displays
What happens without rest
- Coil burnout (common failure)
- Warped or stuck mechanisms
- Random resets or glitches from power instability
- Shortened lifespan of electronics and wiring
- Increased maintenance and downtime
Why it’s more critical in venues
- Continuous back-to-back usage (no natural idle time)
- Higher ambient temperatures (crowds, lighting)
- Machines pushed harder than typical design assumptions
Best practice
- Implement enforced idle/cooldown periods in software
- Avoid continuous attract modes that heavily use coils or motors
- Use fans or ventilation where possible
- Respect manufacturer duty cycle specs for coils
- Monitor temperature on high-load components in custom builds
Bottom line
Electromagnets and other high-load components are thermally limited. Without periodic cooldown, heat accumulation leads directly to failure. Controlled rest periods significantly extend machine lifespan and reliability.
