Why a Larger Gate Motor Is Not Always the Right Solution
One of the biggest misconceptions in automatic gate automation is that installing a larger motor automatically results in a better-performing gate.
Professional motor selection is far more complex.
The correct automation system is chosen by evaluating the complete gate—not simply its size.
A Real Example from Winston Hills
A recent project in Winston Hills perfectly demonstrates this principle.
The property featured an 8-metre sliding gate.
At first glance, many installers would recommend a motor larger than the Benincà BULL624 Turbo simply because of the gate's length.
However, our lead technician approached the project differently.
Rather than relying on gate length alone, he evaluated the complete operating characteristics of the gate, including:
Actual gate weight
Rolling resistance
Wheel condition
Track alignment
Gate balance
Daily operating frequency
Mechanical efficiency
Long-term reliability
After completing the assessment, he recommended installing the Benincà BULL624 Turbo.
The result was exactly what good engineering should achieve.
The client avoided paying for a larger, more expensive motor that wasn't necessary while also benefiting from the faster operating speed of the BULL624 Turbo. The finished system provides reliable performance without unnecessary oversizing.
This project highlights an important principle in gate automation:
Experience and engineering judgement often matter more than specifications on paper.
Every Gate Is Different
A gate motor should never be selected based solely on gate length.
Professional motor selection considers:
Gate weight
Gate length
Gate height
Daily operating cycles
Wind exposure
Ground slope
Track condition
Wheel and bearing condition
Gate balance
Structural rigidity
Safety requirements
These factors determine how much force the motor actually needs to deliver throughout its service life.
Weight Is Only One Part of the Equation
Two gates with identical dimensions may require completely different automation systems depending on their construction, friction, balance and frequency of use.
A properly engineered system focuses on overall efficiency rather than simply increasing motor size.
Mechanical Condition Matters More Than Motor Size
Installing a larger motor will not compensate for mechanical problems.
Issues such as worn wheels, damaged tracks, bent racks, poor alignment or excessive friction should always be addressed first.
A smooth-running gate places significantly less stress on the automation system and dramatically improves reliability.
Correct Engineering Saves Money
Choosing the correct motor offers significant long-term benefits:
Avoids unnecessary equipment costs.
Provides smoother operation.
Delivers faster opening and closing speeds where appropriate.
Reduces wear on the automation system.
Improves long-term reliability.
Minimises future maintenance.
Professional gate automation isn't about installing the biggest motor available—it's about selecting the right motor for the specific application.
At Gate Automation NSW, every recommendation is based on engineering principles, real-world experience and a thorough assessment of the complete gate system. This approach ensures each client receives the most reliable and cost-effective solution for their property.
