Choosing the Right Motor for Car Park Roller Shutters

Car park shutters are an essential part of modern building security. Whether it’s a multi-storey residential block, an office car park, or a high-traffic public facility, the shutter must open and close reliably to keep vehicles and property secure. The motor driving the shutter is the heart of this system. Selecting the right motor ensures not only smooth operation but also long-term durability and compliance with safety standards.

In this guide, we’ll explain the main types of shutter motors – Tube, Inboard, and Direct Drive – as well as GFA’s high usage and high-speed motors. We’ll also suggest which motor types suit different car park sizes, highlight why over-specifying is always safer than under-specifying, and explain why frequent servicing is critical for heavily used shutters.

Types of Motors for Car Park Shutters

Tube Motors

• Tube motors are compact and sit inside the barrel of the shutter.
• Best for: Light duty applications, smaller shutters, and residential or small office car parks with a couple of spaces.
• Advantages: Space-saving, cost-effective, and suitable for low cycle use (around 5–10 operations per day).
• Limitations: Not designed for continuous or high-frequency use, so unsuitable for busy multi-bay car parks.

Inboard Motors

• Inboard motors are fitted to the end of the shutter barrel with chain drive options available.
• Best for: Medium-sized shutters in small commercial car parks with moderate traffic (e.g., 10–20 car spaces).
• Advantages: Stronger than tube motors, easy to service, and capable of higher cycle rates.
• Limitations: Still limited compared to direct drive or GFA high usage motors when traffic demand is high. 

Direct Drive Motors

• Direct drive motors connect directly to the barrel, providing maximum torque and reliability.
• Best for: Large shutters in commercial or residential car parks with 20-30 spaces.
• Advantages: Built for high-duty cycles, robust, and low maintenance compared to chain systems.
• Limitations: Higher upfront cost but long-term reliability offsets this.

GFA High Usage Motors

GFA is a leading brand for industrial shutter motors, offering specialised high usage options.

• Best for: Car parks with 30+ spaces or constant traffic flow, such as shopping centres, hospitals, and airports.
• Advantages:
  • Designed for intensive, continuous operation.
  • Built-in safety features and precise limit settings.
  • Heavy-duty components with long service life.
• Example: GFA SI (servo-inverter) systems allow controlled acceleration and deceleration to reduce wear.

GFA High Speed Motors

Where speed of access is critical, GFA high speed motors are the solution.

• Best for: High-security sites, logistics facilities, or busy urban car parks where traffic build-up must be avoided.
• Advantages:
  • Rapid opening and closing reduces waiting time.
  • Reduces exposure of vehicles and occupants during entry/exit.
  • Minimises draughts, noise, and energy loss for internal car parks.

Matching Motors to Car Park Size

Here’s a practical way to think about motor selection based on car park usage:

• Up to 3 spaces: Tube motor may be sufficient (low cycle use).
• 10–20 spaces: Inboard motor for medium duty.
• 50–200 spaces: Direct drive motor for high reliability.
• 200+ spaces or continuous traffic: GFA high usage motor.
• Sites with congestion risk: GFA high speed motor.

Why Over-Specifying the Motor Matters

When choosing a shutter motor, it is always better to over-specify than under-specify. An underpowered motor will:

• Struggle under daily loads.
• Fail prematurely, leading to costly downtime.
• Increase safety risks due to potential motor burnout or shutter jamming.

By contrast, a slightly over-spec’d motor runs with less strain, extends product lifespan, and reduces the likelihood of breakdowns.

Servicing and Maintenance Considerations

The more frequently a motor is used, the more often it must be serviced. For example:

• Tube motors may only need annual servicing.
• Direct drive and inboard motors should be inspected twice per year.
• GFA high usage motors often require quarterly servicing to maintain performance and warranty compliance.

Regular maintenance ensures:

• Safe operation.
• Compliance with workplace health and safety regulations.
• Reduced risk of unexpected downtime.

Conclusion

The motor you choose for your car park shutter determines how smoothly, safely, and reliably it will operate. From compact tube motors for small car parks to GFA high usage and high speed motors for large, busy facilities, selecting the right option is about matching the motor capacity to traffic volume – and always opting to over-spec rather than under-spec.
