The Service Interval That Disappeared.
What Roger Engineered Out of the System.
A component-by-component breakdown of what conventionally wears in a gate operator's working life — and how the Roger brushless architecture eliminates each one by design rather than by improvement.
Most engineering improvements iterate on existing components — better brushes, longer-life capacitors, more robust relays. Roger's brushless platform takes a different approach: the components themselves are removed from the design wherever possible. The service items that define the maintenance schedule of a conventional gate operator are not engineered to last longer on a Roger — they're engineered out entirely.
Wear Items on a Schedule
The traditional gate operator has a predictable wear profile, built into its architecture. Its primary service consumables define the maintenance schedule.
Carbon brushes
Brushed DC operators carry current to the rotor through carbon brushes pressed against a rotating commutator. Each brush wears with use, generates carbon dust that contaminates the commutator and surrounding components, and arcs every time the commutator segments switch. Brushes are routine consumables — replacement is part of the planned service schedule.
Motor capacitors
230V AC capacitor-start operators rely on a starting capacitor to create the phase shift needed to spin a single-phase motor, and, on capacitor-start-capacitor-run designs, a run capacitor for ongoing operation. Electrolytic capacitors age — capacitance declines, equivalent series resistance rises — and eventually fail. Starting capacitors fail more frequently because they're exposed to high inrush conditions on every cycle. Capacitor failure is the single most common cause of “gate won't start” service calls on 230V AC operators.
“None of these consumables is a design failure. They're the unavoidable wear items of the architecture, and the trade has built service schedules around them for decades.”
No Failure Mode in the First Place
The Roger brushless architecture replaces each conventional consumable with a design that doesn't have the failure mode in the first place.
The motor is a three-phase permanent-magnet synchronous machine. The rotor is pulled by a rotating magnetic field generated electronically by the stator windings — there is no mechanical contact carrying current to the rotor. Brushes don't wear because there are no brushes. Carbon dust doesn't accumulate because nothing produces it. Commutator arcing doesn't occur because there is no commutator.
The three-phase waveform is synthesised by the four-quadrant MOSFET inverter from the DC bus. Starting torque is produced by software-controlled current shaping at the moment of startup — no capacitor mechanism is involved. There is no motor-side starting capacitor and no motor-side run capacitor in the power chain. The single largest electrolytic failure mode in 230V AC gate automation is removed entirely.
Direction is reversed in solid-state silicon by reversing the phase sequence the inverter generates. There are no mechanical contacts to wear, no contactor to weld, no relay arcing. The same MOSFET inverter that drives the motor handles reversal at PWM frequencies far above audible.
A Different Conversation at Quote Time
A Roger installation has a fundamentally lower planned maintenance burden, which lets the installer offer longer warranty backing without service-call exposure. The Edgesmith Platinum Partner Program is structured around this — manufacturer warranty plus a one-year Edgesmith-backed extension.
The build quality starts inside the motor: the components and the way they’re put together let a Roger operator handle heavy daily use without losing performance. For the installer, that means fewer callbacks and gates that keep running reliably.
Roger is priced to compete, but the real difference shows over the life of the installation. Very few parts are subject to wear, so servicing is quick and simple. Add a longer service life and a product your clients can count on, and it pays for itself. You’re not just selling a motor, you’re selling a long-term solution.
Installations that don't generate maintenance callbacks build referral business that does. Customers who have a Roger for ten years without seeing the installer come back tell their neighbours.
Engineered Out, Not Improved Within
Conventional gate operators wear out on a predictable schedule because their architecture has predictable wear items. Roger's brushless platform doesn't have those wear items — they're engineered out of the design rather than improved within it.
This is the architectural foundation of the long warranty cover Roger and Edgesmith offer on the brushless range. It isn't marketing optimism. It's a function of removing the components whose failures define the warranty exposure in the first place.
Selling the Decade, Not the Day.
Price is the easiest number to compare on a quote, and the least informative. Two operators can sit close together on commissioning day and a long way apart years later, once every service visit in between has been counted.
That is a harder conversation than price, and it's one this architecture lets an installer have honestly — because the components that set a conventional maintenance schedule aren't there to fail.
We don't simply resell a brand. We choose components we can stand behind technically, and we explain them properly so installers and specifiers can make informed decisions. We distribute engineering, not motors.
