EP-EM1091 Single-Stage High-Speed Planetary Gearbox<\/h1>\n

Brevini Riduttori EM1091 Compatible Replacement | EVER POWER<\/p>\n

The EM1-series<\/strong> 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<\/strong> where minimal energy loss and low backlash at high input speed are the primary requirements.<\/p>\n

The EP-EM1091<\/strong> replaces the Brevini riduttori EM1091<\/strong> ?? a single-stage planetary gearbox delivering approximately 4,400 Nm<\/strong> output torque, ratio range 3:1 – 10:1, and IP rating IP65.<\/p>\n

Working Principle<\/h2>\n

\"EVER<\/p>\n

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<\/strong> 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<\/strong> handle combined axial and radial loads from cantilever-mounted drive elements.<\/p>\n

Core Advantages<\/h2>\n\n\n\n\n
\n
● 98% Efficiency<\/strong>
Single-stage ?? lowest gear mesh loss in the EC\/EM range.<\/div>\n<\/td>\n
\n
● 6,000 rpm Input Speed<\/strong>
Servo motor compatible ?? no input speed de-rating required.<\/div>\n<\/td>\n<\/tr>\n
\n
● Minimal Backlash<\/strong>
Tight planet tolerance gives precise positioning response.<\/div>\n<\/td>\n
\n
● Compact Single-Stage Housing<\/strong>
Shortest axial length in size class ?? fits servo motor adaptor plates.<\/div>\n<\/td>\n<\/tr>\n
\n
● Direct Brevini EM1-Series Fit<\/strong>
Same flange and shaft dimensions ?? zero machine modification.<\/div>\n<\/td>\n

Structure and Material Technology<\/h2>\n

\"EVER<\/p>\n

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