Why Planetary Drives
Planetary gearing uses a central sun gear, multiple planets, a ring gear, and a carrier to distribute power through several meshes. That geometry can deliver high torque density in a concentric package while supporting a wide range of ratios and output arrangements.
- High torque density for constrained envelopes
- Coaxial, parallel, and right-angle architectures
- Scalable from precision motion to heavy process duty
- Dedicated travel, wheel, and slew support arrangements

Input
Power enters through a sun gear, ring gear, or carrier depending on the architecture.
Load Sharing
Multiple planet meshes distribute torque around the central axis.
Reaction
One member is fixed or controlled to establish the kinematic relationship.
Output
The remaining member delivers the required speed and torque.
Customization Options
Input Integration
IEC motor adaptors, hydraulic-motor interfaces, keyed inputs, and application-specific connections.
Output Geometry
Solid shafts, splines, hollow shafts, shrink-disc arrangements, flanges, and integral pinions where supported.
Duty Package
Brake, valve, lubrication, cooling, sealing, mounting, and inspection scope defined from the application.
Key Parameter Range
| Family | Published / Documented Envelope | Best Starting Point |
|---|---|---|
| EP300 | Reference torque classes 1,000–105,000 N·m | General modular industrial drives |
| EP400 | 1,000–220,000 N·m; i 5.3–365 | Tracked final drives |
| EP600 | 1,750–60,000 N·m; i 5.8–160 | Wheel and drum drives |
| EP700 | Family to 80,000 N·m; ratios into multi-stage range | Slewing and rotating structures |
| EPP | 0.4–12,934 kW; i 25–4,000; to 2,600 kN·m | Heavy industrial process drives |
| PAB/PABR/PPG | 9–2,000 N·m family ranges; published backlash classes | Servo and precision motion |
Ranges above come from connected Ever-Power catalogues and current official Ever-Power product pages. Each model and ratio has its own limits; final selection requires engineering review.
Selection Guide
- Define the motion: input speed/power, output speed/torque, peak events.
- Classify the duty: hours, starts, reversals, shock, holding, lifecycle.
- Freeze the interface: motor, shaft, spline, flange, mounting, external loads.
- Check the environment: temperature, dust, moisture, corrosion, washdown.
- Verify thermal and life margins: especially for continuous or high-speed duty.
- Approve the drawing: dimensions and configuration before production.
