What EVER-POWER Clients Say
Sourced industrial planetary gearbox units for our offshore winch upgrade. The engineering team at UK Ever-power understood the shock-load requirements immediately and recommended the right WinchDrive specification. Competitive pricing and flawless documentation for our certification audit.
We specified a bespoke planetary gearbox gear ratio of 250:1 for our new conveyor head drive. UK Ever-power turned around a full technical drawing in 36 hours and delivered in six weeks. Build quality is excellent and the unit has run without issue for eight months now.
The right angle planetary gearbox we ordered for our robotic welding cell fits perfectly within the tight envelope and gives us the servo compatibility we needed. UK Ever-power provided full CAD files on request — saves enormous time in integration. Would not hesitate to recommend to other engineers.

What is a planetary gearbox and how does it work?
A planetary gearbox is an epicyclic gear arrangement in which planet gears orbit a central sun gear within a fixed outer ring gear (annulus). Understanding what is a planetary gearbox and how a planetary gearbox works begins with this: load is shared simultaneously across three or more planet gears, producing exceptional torque density in a compact axial envelope. The result is a highly efficient, low-backlash drive train widely used in industrial machinery, mobile equipment, and renewable energy systems.
What planetary gearbox gear ratio range is achievable?
The achievable planetary gearbox gear ratio depends on the number of teeth on the sun, planet, and ring gears. A single epicyclic stage typically delivers ratios from 3:1 to 10:1. By cascading two or three stages, UK Ever-power engineers can achieve gearbox planetary ratios of up to 1000:1 or higher, enabling very high torque output from compact, high-speed motors. Custom intermediate ratios are available on request with full engineering documentation.
What are high speed planetary gearbox applications?
A high speed planetary gearbox is used where an electric motor or turbine running at 1,000–3,600 RPM must be stepped up or down with minimal losses. Typical applications include wind turbine nacelles, centrifugal compressors, high-cycle servo axes, and aerospace test rigs. UK Ever-power designs industrial planetary gearbox units for high-speed input — using precision-ground helical planet gears, needle roller planet bearings, and dynamic balancing to achieve quiet, vibration-free operation at elevated speeds.
When should I choose a right angle planetary gearbox?
A right angle planetary gearbox combines a bevel or hypoid input stage with a planetary reduction stage to redirect shaft rotation through 90°. This configuration is preferred when machine geometry requires a perpendicular drive — for example in robotic joints, conveyor corner drives, and axis-constrained automation. UK Ever-power’s right angle planetary gearbox range maintains the full torque rating and backlash performance of inline models, with optional hollow shaft output for direct shaft mounting.
How do I select the right transmission planetary gearbox for my application?
Selecting a transmission planetary gearbox requires defining input speed (RPM), required output torque (Nm), gear ratio, mounting configuration, and environmental conditions. UK Ever-power’s engineering team uses this data to size the correct gearbox planetary series, calculate thermal rating under duty cycle, and recommend sealing specification for your environment.
