EP-EM1091 Single-Stage High-Speed Planetary Gearbox
Brevini Riduttori EM1091 Compatible Replacement | EVER POWER
The EM1-series is a single-stage planetary gearbox delivering the highest efficiency in the EC/EM family. With up to 98% efficiency per pass and input speed up to 6,000 rpm, it is the preferred choice for servo motor direct coupling, high-speed spindle drives, precision indexing and motion control applications where minimal energy loss and low backlash at high input speed are the primary requirements.
The EP-EM1091 replaces the Brevini riduttori EM1091 ?? a single-stage planetary gearbox delivering approximately 4,400 Nm output torque, ratio range 3:1 – 10:1, and IP rating IP65.

動作原理

A single planet stage receives motor input on the sun gear shaft. Planet gears orbit the sun and react against a fixed ring gear, multiplying torque at the planet carrier output. The single-stage architecture provides the lowest possible gear mesh losses ?? critical for servo-driven axes where heat generation in a compact housing would otherwise require motor de-rating. Angular contact output bearings handle combined axial and radial loads from cantilever-mounted drive elements.
主な利点
|
● 98% Efficiency
Single-stage ?? lowest gear mesh loss in the EC/EM range. |
● 6,000 rpm Input Speed
Servo motor compatible ?? no input speed de-rating required. |
|
● Minimal Backlash
Tight planet tolerance gives precise positioning response. |
● Compact Single-Stage Housing
Shortest axial length in size class ?? fits servo motor adaptor plates. |
|
● Direct Brevini EM1-Series Fit
Same flange and shaft dimensions ?? zero machine modification. |
構造と材料技術

Housing is precision-cast from GGG40 aluminium-alloy or GGG50 ductile iron depending on size. Planet gears use 20CrMnTi case-hardening steel, carburised and ground to ISO class 5 accuracy. Angular contact ball bearing pairs on the output shaft provide pre-loaded zero-play support for reversing servo loads. All seals are FKM fluoroelastomer rated for synthetic oil at up to 120 degC.

よくある質問
Q: Is the EM1-series compatible with servo motor feedback encoders?
A: Yes. The housing flange accepts standard servo motor adaptors with encoder feedback cable routing channels. Specify your motor make and model for confirmation.
Q: What is the rated backlash?
A: Standard backlash is <= 8 arcmin. A premium reduced-backlash option (<= 5 arcmin) is available for high-precision servo axes ?? specify at order.
