iFIT Series
The iFIT Series features helical inline, bevel helical, and parallel shaft helical gearmotors. Key attributes include full interchangeability with market standards, robust cast iron housing, and high-quality sealing solutions. Benefits include energy savings, low noise levels, and up to 12% higher torque than market standards.

E Series
The E Series offers coaxial gear reducers and gearmotors with universal mounting options and a wide range of sizes, suitable for heavy-duty applications due to their long life, minimal maintenance, and high performance.

AS Series
The AS Series focuses on worm gear reducers and gearmotors, featuring rigid cast iron housing and nickel bronze worm wheels for high load capacity and reliability, offering long running life and reduced power consumption.

G Series
The G Series includes helical and bevel helical gear reducers and gearmotors, designed for extruder applications with high structural stiffness and a wide range of sizes, suitable for heavy-duty applications.

GX Series
Similar to the G Series, the GX Series is designed for extruder applications, offering additional support for heavy applications.

H Series
The H Series provides helical and bevel helical gear reducers with a wide torque range and customizable solutions for heavy industry applications.

EP Series
The EP Series includes planetary gear reducers and gearmotors, offering modular design and high torque transmission, suitable for both coaxial and right-angle units.

SR Series
The SR Series features worm and helical servo gear reducers, designed for high torsional stiffness and low angular backlash, suitable for various servo motors.

Additional Features and Benefits
Rossi emphasizes features such as universal mounting, robust housing, high efficiency, and a wide range of accessories across its product lines. Benefits include easy installation, high performance, reliability, and energy efficiency, catering to a broad spectrum of industrial applications.

Shaft Mounting and Torque Specifications
The document outlines specifications for shaft mounting solutions dedicated to conveyors, available in seven sizes ranging from 80 to 320, with nominal torque reaching up to 6,000 Nm and a transmission ratio of 1 to 6.25. Another set of sizes, from 85 to 250, offers nominal torque up to 11,200 Nm with a transmission ratio of 10 to 25.

Motor Series
TX Series: Asynchronous three-phase standard and brake motors with frame sizes from 63 to 180, offering nominal power from 0.12 to 22 kW.
HB Motors: Feature asynchronous three-phase motors with squirrel cage rotors, TEFC, and IE3 efficiency class, suitable for inverter duty with large thermal reserves and lightweight diecast aluminum housing.
HE Motors: Offer asynchronous three-phase motors with frame sizes from 160 to 315, available in IE3 and IE4 efficiency classes, suitable for multiple voltage and frequency ratings.
S Series: Heavy-duty roller table motors designed for high resistance to mechanical shocks and inverter feeding electrical stress, with frame sizes from 112 to 250.

Motion Control and Inverters
The document describes the dDrive Inverter Series, which includes decentralized frequency inverters designed for Rossi IE2 and IE3 electric motors. These inverters feature sensorless vector control, Safe Torque Off (STO), and a configurable I/O board, suitable for harsh environmental conditions and offering high safety performance levels.
