EP-EC3030 3-Stage Compact Planetary Gearbox
Brevini Riduttori EC3030 Compatible Replacement | EVER POWER
The EC3-series extends the compact housing concept to three stages, providing reduction ratios up to 150:1 in a housing diameter typically 12-18% smaller than an equivalent ET3-series unit. It is ideal for compact industrial drives, small tracked equipment, tight-envelope hoists, narrow conveyor drives and space-constrained machine tool axes where the 3-stage ratio range is needed but the machine frame cannot accommodate a full-size 3-stage housing.
The EP-EC3030 replaces the Brevini riduttori EC3030 ?? a 3-stage compact planetary gearbox delivering approximately 2,450 Nm output torque, ratio range 15:1 – 150:1, and IP rating IP65.

Working Principle
Three stages are nested coaxially in a reduced-diameter housing. The inter-stage floating sun shaft self-aligns between stages, eliminating any bending moment that would otherwise distort the sun gear teeth under offset loading in the compact housing. A precision output flange register ?? machined to 0.015 mm TIR ?? ensures accurate sprocket and coupling mounting without eccentricity in the narrower housing.
Core Advantages
|
► 12-18% Smaller OD vs ET3
Same ratio range in a narrower housing ?? fits more machine designs. |
► Floating Sun Shaft
Eliminates bending moment in compact inter-stage bore. |
|
► 0.015 mm Output Register TIR
Precise sprocket mounting without eccentricity. |
► Up to 150:1 Ratio
3-stage compact covers full reduction range for tight spaces. |
|
► Direct EC3-Series Replacement
Identical flange dimensions as Brevini original. |
Structure and Material Technology
Housing is cast from GGG50 ductile iron and bore-ground to minimise material thickness in ring gear zones. Planet gears use 17CrNiMo6 carburised steel, ground to DIN 5. Sealed-for-life angular contact bearings on input and output shafts eliminate external lube points in compact installations. External paint is two-coat industrial epoxy, 400h salt spray.
Typical Application Scenarios
| Industry | Application | Key Benefit |
|---|---|---|
| Food | Portioning conveyor drive | IP65 sealing for food-grade wash-down compliance. |
| Packaging | Carton erector drive | Reliable high-cycle servo drive for carton forming. |
| Textile | Yarn winding tension drive | Precise speed regulation for consistent winding tension. |
| Automation | Guided vehicle wheel drive | Compact housing for narrow-profile AGV wheel assemblies. |
Selection Guide
- Required Output Torque (Nm) ?? Confirm peak and continuous with safety factor (1.3-2.0 typical).

Frequently Asked Questions
Q: What is the advantage of the EC3 over the EC2 in the same size class?
A: The EC3 provides up to 150:1 ratio versus 40:1 for the EC2. Choose EC2 when speed is more important; EC3 when higher reduction is needed in the same compact housing.
Q: Are sealed-for-life bearings standard?
A: Yes on input and output shafts. No external lubrication points on these bearings. Internal gear oil still requires periodic change as per standard schedule.
