Roger TORQUE vs TRADITIONAL VOLTAGE Motors
Why Roger Brushless Motors Represent a Different Engineering Class
A fundamentally different approach to motion control
Its brushless gate operators are built around a low-voltage (24 V / 36 V AC) three-phase permanent magnet synchronous motor (PMSM), driven by a fully digital inverter integrated in their control boards, using Field-Oriented Control (FOC).
This architecture allows the system to regulate current and torque directly, rather than passively depending on voltage. The result is not just higher performance and control, but longer lifespan, energy efficiency and an operator that remains reliable even under demanding conditions.
Torque control, not voltage dependence
In a conventional brushed DC motor, torque is largely a consequence of applied voltage and motor speed. As speed decreases, particularly during slowdown phases, available torque drops. This is why many standard operators feel weak near the end-of-travel or under load.
Roger’s brushless PMSM behaves differently. Thanks to FOC, the controller continuously adjusts phase currents to maintain essentially constant torque across the entire speed range. Acceleration, cruising, deceleration and holding phases are all managed with the same level of authority.
This constant-torque behaviour is the reason Roger motors are correctly referred to as TORQUE motors, not voltage motors.
Continuous operation by design
Another direct consequence of the brushless architecture is true continuous operation.
Without brushes, there is no frictional commutation heat. The stator-mounted windings dissipate heat efficiently through the motor body, and current draw remains extremely low even under load. Roger’s own testing and product ratings confirm 100% duty cycle capability.
In real installations, this means the motor can operate without interruption—no thermal shutdown, no forced rest, no drop in performance. This is a core advantage over brushed DC motors, which often require downtime between cycles.
Digital safety and immediate response
Because torque is always available and digitally regulated, safety reactions are immediate and smooth.
When an obstacle is encountered, the system instantly detects torque variation and can reverse direction without delay or braking. The motor doesn't need to build up torque—it's already under control. This responsiveness is only possible with fully digital brushless systems.
| Roger TORQUE Motor | Standard 24 V DC VOLTAGE Motor | |
|---|---|---|
| Motor type | Brushless 3-phase PMSM | Brushed DC |
| Control principle | Digital inverter with FOC (torque control) | Voltage / PWM-based |
| Torque behavior | Constant across all speeds | Drops at low speed |
| Duty cycle | True 100% continuous | Limited, requires cool-down |
| Position feedback | Sensorless via back-EMF + internal absolute | External encoders/limit switches |
| Obstacle Detection | Fast and responsive | Delayed |
| Thermal behavior | Cool operation even under load | Generates significant heat |
| Long-term stability | No wear components | Brushes and relays wear over time |
Why Installers Choose Roger
Roger's brushless platform offers tangible, real-world advantages for installers and automation professionals:
- Simplified wiring: Swing gate motors require only a single 3-core cable. Thanks to integrated digital control and sensorless + sensored absolute positioning, installers can achieve perfect positioning and smooth ramps.
- Fewer service calls: The absence of mechanical brushes and relays eliminates common failure points such as contact wear or inconsistent performance. Smooth, precise movement minimises strain on mechanical components, extending the life of both the motor and the gate.
- Long lifespan: Roger products are engineered and manufactured entirely in-house with uncompromising material selection and mechanical expertise. Each gear and motor is optimised for strength and longevity—making it a true “install and forget” solution.
- Industrial opportunities: In high-traffic and heavy-duty gate applications, Roger brushless operators consistently outperform conventional 24 V systems. This gives installers a competitive edge when targeting industrial or commercial projects—they’re fast and high torque.
- Low-voltage advantage: Even the most powerful Roger operators run at 24/36 V, eliminating the need for licensed electrician certification. Backup battery systems can be easily integrated, ensuring continued operation during power outages.
- Training and support: Edgesmith is committed to empowering automation professionals with technical training, responsive support, and industry-leading customer service. Whether it's project advice or troubleshooting, our experts are here to help you succeed.
Conclusion
Roger Technology’s brushless TORQUE motor is not a minor upgrade to existing 24 V DC motors; it’s an entirely different engineering solution. It combines industrial-grade motor control with low-voltage safety and digital intelligence.
Brushless architecture, constant torque, integrated absolute feedback, and seamless performance under continuous use: these are not marketing claims; they are factual consequences of the technology.
This is the difference between powering a gate with voltage and controlling motion with TORQUE.
