Epicyclic gears obtain name from their earliest app, which was the modelling of the motions of the planets in the heavens. Believing the planets, as everything in the heavens, to become perfect, they could just travel in ideal circles, but their motions as seen from Earth could not end up being reconciled with circular motion. At around 500 BC, the Greeks developed the thought of epicycles, of circles venturing on the circular orbits. With this theory Claudius Ptolemy in the Almagest in 148 AD could predict planetary orbital paths. The Antikythera Mechanism, circa 80 BC, experienced gearing which was able to approximate the moon’s elliptical path through the heavens, and actually to correct for the nine-calendar year precession of that path. (The Greeks could have seen it much less elliptical, but instead as epicyclic motion.)
EP, a versatile and multi-use answer, is not only another simple planetary gearbox. EP high-tech planetary reducer is definitely a true integrated concept, including different functions combined alongside one another to give a complete sub-assembly to the virtually all demanding machines.
EP is the ultimate high-tech servo-reducer, specially dedicated to designs requiring:
Superior output torsional stiffness
Ultra-excessive output radial stiffness and Tilting moment
Patented output bearing design
A high-tech planetary gear train, based on REDEX’s differential know-how
ISO 9409-1 end result drive flange for installation pinions, pulleys, couplings, etc.
High input speeds
Superior acceleration and excellent torque density
Minimum backlash (1 – 3 arc-minutes)
In-Line or correct angle arrangements
This versatile design makes it possible for design engineers to find precise answers to the most demanding applications.

The S Series style causes this gearmotor particularly effective for pump, fan and blower applications. To meet the needs of customers in these sectors, the S Series is also available in the feet or flange versions and may be completed with an array of electric motors entirely made by EP. Asynchronous motors both IEC and small (B-BE-BX/M-ME-MX), servomotors (BMD) and reluctance motors (BSR) could be coupled with the S Series: with the breadth of its portfolio, EP provides buyers with a superb balance of cost efficiency, efficiency and dynamics.
The combination of epicycle gear trains with a planet engaging both a sun gear and a ring gear is named a planetary gear train. In this case, the ring equipment is usually fixed and the sun gear is driven.
