Epicyclic gears get their name from their earliest program, that was the modelling of the movements of the planets in the heavens. Believing the planets, as everything in the heavens, to be perfect, they could just travel in ideal circles, but their motions as viewed from Earth could not be reconciled with circular movement. At around 500 BC, the Greeks created 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 System, circa 80 BC, got gearing which was in a position to approximate the moon’s elliptical path through the heavens, and also to improve for the nine-calendar year precession of that route.[3] (The Greeks could have seen it much less elliptical, but rather as epicyclic motion.)
EP, a versatile and multi-use alternative, is not only another simple planetary gearbox. EP high-tech planetary reducer is usually a genuine integrated concept, including different functions combined together 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-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 outcome drive flange for mounting pinions, pulleys, couplings, etc.
High input speeds
Superior acceleration and superb torque density
Minimum backlash (1 – 3 arc-minutes)
In-Line or correct angle arrangements
This versatile Planetary Reducer Gearbox design makes it easy for design engineers to find exact answers to the most demanding applications.
Parallel shaft Gearmotors
Helical Single-Stage
The S Series style makes this gearmotor particularly effective for blower applications, pump and fan. To meet up the needs of consumers in these sectors, the S Series is also available in the foot or flange types and can be completed with an array of electric motors entirely produced by EP. Asynchronous motors both IEC and compact (B-BE-BX/M-ME-MX), servomotors (BMD) and reluctance motors (BSR) could be in conjunction with the S Series: with the breadth of its portfolio, EP provides buyers with an outstanding balance of efficiency, dynamics and cost effectiveness.

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 this case, the ring gear is usually fixed and the sun gear is driven.
