Epicyclic gears get their name from their earliest program, that was the modelling of the actions of the planets in the heavens. Believing the planets, as everything in the heavens, to end up being perfect, they could only travel in ideal circles, but their motions as seen from Earth cannot end up being reconciled with circular motion. At around 500 BC, the Greeks invented the thought of epicycles, of circles venturing on the circular orbits. With this theory Claudius Ptolemy in the Almagest in 148 AD was able to predict planetary orbital paths. The Antikythera System, circa 80 BC, acquired gearing which was able to approximate the moon’s elliptical route through the heavens, and actually to correct for the nine-yr precession of that path.[3] (The Greeks could have seen it not as elliptical, but rather as epicyclic motion.)
EP, a versatile and multi-use option, is not simply another simple planetary gearbox. EP high-tech planetary reducer is definitely a true integrated concept, including more than a few functions combined jointly to give you a complete sub-assembly to the most demanding machines.
EP is the best high-tech servo-reducer, specially dedicated to designs requiring:
Superior output torsional stiffness
Ultra-huge output radial stiffness and Tilting moment
Patented output bearing design
A high-tech planetary equipment train, predicated on REDEX’s differential know-how
ISO 9409-1 result drive flange for installation pinions, pulleys, couplings, etc.
High input speeds
Superior acceleration and good torque density
Minimum backlash (1 – 3 arc-minutes)
In-Line or correct angle arrangements
This versatile design helps it be possible for design engineers to find specific answers to the most demanding applications.
Parallel shaft Gearmotors
Helical Planetary Reducer Gearbox Single-Stage
The S Series design causes this gearmotor particularly effective for blower applications, fan and pump. To meet up the needs of customers in these sectors, the S Series can be available in the foot or flange editions and can be completed with a wide selection of electric motors entirely created by EP. Asynchronous motors both IEC and small (B-BE-BX/M-ME-MX), servomotors (BMD) and reluctance motors (BSR) can be coupled with the S Series: with the breadth of its portfolio, EP provides consumers with a superb balance of dynamics, cost effectiveness and efficiency.

The mixture of epicycle gear trains with a planet engaging both a sun gear and a ring gear is called a planetary gear train.[1][2] In cases like this, the ring gear is generally fixed and sunlight gear is driven.
