Tutti i componenti sono prodotti da Moog nel rispetto dei più severi standard di affidabilità e qualità. Presentati in fiera anche attuatori lineari e azionamenti In fiera Moog ha presentato anche gli attuatori lineari elettro-compatti multi-purpose MEMA (Multipurpose Electro-Mechanical linear Actuator), che nascono dalla sinergia tra i servomotori brushless, i servoazionamenti Moog e la tecnologia delle viti a ricircolo di sfere e rulli satelliti. Perfettamente integrabili con i Servodrive Moog, consentono un’ottimizzazione delle prestazioni delle macchine. Tra i principali benefici degli attuatori MEMA si evidenziano la massima precisione, per un più accurato controllo del moto, basse inerzie al fine di ottenere maggiori accelerazioni e silenziosità rispetto ai sistemi idraulici tradizionali. Infine, la notevole capacità di sovraccarico dei motori assicura elevate accelerazioni e decelerazioni, a garanzia di alte dinamiche e di un migliore tempo di ciclo. Sono stati inoltre presentati gli azionamenti a bordo motore e a bordo macchina DI2020 e DR2020, che completano la gamma degli ultracompatti DS2020 e DM2020 rispettivamente singolo e multiasse, così come le nuove taglie di servomotori Fastact serie H, progettati per applicazioni dove viene privilegiata l’erogazione di valori intermedi di coppia rispetto a valori di picco. l NEWS ARTICLE - mechanics New Generation Electrohydrostatic Actuation System Moog’s electrohydrostatic actuation system combines the benefits of both electromechanical and electrohydraulic actuation technologies in a compact design.

This technology enhances productivity thanks to the reduction of idle times and the increase in energy efficiency. Moog’s new generation Electrohydrostatic Actuation System (EAS) was among the novelties launched at SPS IPC Drives Italia: an innovative new approach to machine motion control because it combines the benefits of both electromechanical and electrohydraulic actuation technologies. The system offers the energy efficiency and low noise commonly found in electromechanical actuation and robust and reliable control ideal for high forces that is provided with electrohydraulic actuation. As a decentralized motion control system, the EAS eliminates the need for a hydraulic power unit (HPU) and complex piping providing a smaller overall machine input and reducing the total cost of ownership. The EAS has been developed to meet the needs of OEMs, system integrators and endusers, who seek cleaner and more energy efficient machines, easier installation and commissioning, smooth integration with existing The pump unit is at the heart of the actuation system The Moog EPU is at the heart of electrohydrostatic actuation and helps enable the deployment of a decentralized drive system.

on to a cylinder thereby minimizing the requirement of additional space on each axis. The Moog EPU has been developed to meet the needs of original equipment manufacturers (OEMs), system integrators and end-users, who increasingly seek cleaner and energy efficient products without compromising on the requirement for high forces. The EPU is designed for easy installation and commissioning and can be mounted directly on to a cylinder, thereby reducing the number of components required. The self-contained units have reduced chances of leakage and breakdown and help lower ongoing maintenance costs and the total cost of ownership (TCO). The new electrohydrostatic pump unit can be used for a wide range of applications such as metal-forming, heavy industry, injection molding and die-casting, gas and steam turbines and wind turbine pitch control. The electrohydrostatic pump unit is available either as a stand-alone product or as an entire system, called the Electro-hydrostatic Actuation System (EAS). The EAS combines the electrohydrostatic pump unit and any optional parts a customer might need, such as drives, controllers, manifolds, or cylinders. All components are Moog products that meet the highest standards of reliability and quality. Electromechanical linear actuators and drives were also on show Moog’s Electromechanical linear Actuators (EMA) were also showcased at SPS IPC Drives Italia. Designed with Moog’s permanent magnet synchronous servo motors and ball screws and planetary roller screws, these products are matched with Moog Servo Drives to ensure optimized machine performance. The main advantages of these actuators include: high precision for more accurate control of movements, low inertia to obtain superior acceleration, and reduced noise when compared to traditional hydraulic systems. Moog also introduced a decentralized electromechanical solution, the DI2020 and DR2020 servo motors with on-board electronics and decentralized servo drives. These products complete the range of the compact DS2020 and DM2020, single and multi-axis servo drives. On display were also the new sizes of the Fastact H Series servomotors which are designed for applications where the output of intermediate torque values is preferred to peak values. l InMotion www.altramotion.com
