Product Overview
In power transmission, no mechanical system is 100% perfect; energy is always lost to heat and friction. However, in an era where energy costs dictate factory profitability, minimizing that power loss is critical. Engineers must ask: When my servo motor outputs 100 watts of power, how much actually reaches the conveyor belt? SIEMPRE PODER, a leading mechanical innovator based in the Netherlands, engineers planetary gearboxes designed specifically to mitigate friction. Through meticulous gear grinding, advanced synthetic lubrication, and superior bearing architecture, our transmission units achieve class-leading efficiency, ensuring your motors run cooler and your energy bills stay lower.

Working Principle: Where Does the Power Go?
Power loss in a gearbox primarily comes from three sources: Gear Mesh Friction, Bearing Drag, and Lubricant Churning. In older technologies like worm gears, the gear teeth physically slide violently against one another, generating massive heat and losing up to 30% of motor power. Epicyclic gear systems solve this. As the sun gear drives the planet gears around the ring gear, the teeth engage with a pure rolling motion rather than a sliding motion. This rolling action drastically minimizes friction. EVER POWER further optimizes this by precisely grinding the gear teeth to eliminate microscopic surface bumps, allowing the gears to glide effortlessly and transmitting up to 97% of the motor’s true power directly to the load.
How EVER POWER Maximizes Efficiency (Core Advantages)
1. ISO Class 5 Gear Grinding
Rough gears waste energy. Our post-heat treatment grinding process ensures a glass-smooth finish on every gear tooth, reducing friction and the heat it generates.
2. Synthetic Nyogel Lubrication
Standard heavy oil drags against fast-moving gears (churning loss). We use an advanced, low-viscosity synthetic grease that lubricates perfectly without bogging down the mechanism.
3. Low-Friction Rotary Seals
Tight seals keep oil in, but they squeeze the shaft and cause drag. EVER POWER utilizes specialized FKM lip seals designed to maintain a perfect barrier with minimal rotational friction.
4. Full-Complement Needle Bearings
By using cage-less needle bearings inside our planet gears, the rollers are densely packed, distributing weight perfectly and allowing frictionless rotation even under heavy loads.
5. Motor Downsizing Capability
Because you lose less power in the transmission, you can often specify a smaller, cheaper, and less power-hungry servo motor to do the exact same job, saving long-term energy costs.
Structure & Material Craftsmanship
Efficiency relies entirely on structural alignment. If the planet carrier twists under heavy torque, the gears become misaligned, immediately causing binding and power loss. To prevent this, our engineers in the Netherlands design the planet carrier out of a single, solid piece of CNC-machined steel. This extreme rigidity ensures the planet gears stay perfectly parallel to the sun gear, regardless of the load, preserving that 97% power transfer efficiency through the entire life of the gearbox.
Typical Application Scenarios
- Continuous Logistics Conveyors: S1 continuous running motors draw massive power over a year. A highly efficient planetary gearbox significantly cuts the electrical bill compared to a cheap worm drive.
- Mobile Automated Guided Vehicles (AGVs): AGVs run on batteries. Any power lost in the gearbox reduces the robot’s driving range. High efficiency extends battery life and reduces charging downtime.
- Wind Energy Generators: When acting as a step-up drive, any friction in the gearbox directly reduces the amount of electricity fed back into the commercial power grid.
Selection Guide: Calculating Output Torque
Do not be fooled by simple gear ratio math. To size your system properly, you must calculate efficiency.
- The Formula: Output Torque = Motor Torque × Gear Ratio × Gearbox Efficiency.
- Example: If your motor provides 10 Nm of torque into a 10:1 EVER POWER single-stage gearbox, the output is not 100 Nm. It is (10 × 10 × 0.97) = 97 Nm. Account for this 3% loss during design to avoid stalling your machine.

Case Studies (Engineer’s Field Notes)
Solicitud: Continuous ore belt drives.
Review: “We were using massive, inefficient worm gears that generated so much heat they became a fire hazard. We retrofitted the drives with EVER POWER planetary units. The efficiency jump allowed us to downsize the motors by 20%, saving huge amounts of electricity while running completely cool.” – David W., Mining Engineer.
Solicitud: Battery-powered robotic wheel drives.
Review: “Battery life is our bottleneck. Any friction in the drive wheels means the robot goes back to the charger sooner. EVER POWER’s precision grinding and synthetic grease dramatically reduced the rolling resistance. We extended our robot up-time by almost 45 minutes per shift.” – Sarah Jenkins, Fleet Manager.
Solicitud: High-speed servo indexers.
Review: “The low inertia and high power transfer of the EVER POWER series meant our servos didn’t have to work as hard during rapid acceleration profiles. Our motor thermal alarms stopped going off entirely, and the machines run flawlessly.” – Klaus M., OEM Integrator.

Preguntas frecuentes (FAQ)
Q: Why is a 2-stage gearbox less efficient than a 1-stage?
A: Every time gear teeth mesh, there is a tiny amount of friction. A 2-stage gearbox essentially stacks two gearsets together. The power must pass through two sets of sun and planet gears, compounding the minor frictional losses and dropping efficiency from ~97% to ~94%.
Q: Does adding a higher viscosity oil make the gearbox more efficient?
A: Actually, no. Thick, heavy oil causes ‘churning loss’—the gears have to work harder just to push the thick fluid out of the way when spinning at high speeds. This creates heat and lowers efficiency. EVER POWER uses optimized, specific synthetic grease to balance protection and low drag.
Q: How do worm gearboxes compare in efficiency?
A: Worm gearboxes rely heavily on the gears violently sliding against each other rather than rolling. This sliding creates massive heat. A standard worm gear might operate at 60% to 85% efficiency depending on the ratio, vastly underperforming compared to planetary designs.
Q: Does operating temperature affect the efficiency?
A: Yes. During a cold start, the internal grease is slightly thicker, which may temporarily reduce efficiency. However, within a few minutes of operation, the grease warms up to its optimal operating viscosity, restoring peak power transfer.
Q: Can I increase efficiency by reducing the sealing pressure?
A: While removing seals would reduce drag, it would allow contaminants in and grease out, destroying the gearbox. EVER POWER utilizes advanced FKM rotary seals that are chemically engineered to provide maximum protection while maintaining an incredibly low friction coefficient on the rotating shaft.
