Servo motors with new

Servo motors with new multi-turn encoder B&R has now made available its 8LV compact servo motors in multiple sizes with an optional multi-turn encoder without battery backup. The multi-turn position is retained even if the connection between the drive and motor is interrupted. This option removes the need for a buffer battery. The new inductive digital EnDat 2.2 encoders offer a wide variety of safety functions. These also guarantee a very high level of control accuracy and are resistant to disturbances. The motors are available with a 40, 60 or 80 mm flange and cover a power range of 0.1 to 1.3 kW. Their compact dimensions make them the perfect choice for tight enclosures. www.br-automation.com Igus splits slewing ring bearing The known iglidur PRTs from igus are slewing ring bearings that have a lubrication-free liner between the inner and outer rings made of aluminium, which minimises friction between the two rings. A ‘split’ PRT originated from the customer’s request. In this new development, the iglidur PRT has been constructed in such a way that it can be placed, for example, around a pipe or a shaft and then closed again in its ring shape. Unlike the usual iglidur PRTs in the igus range, the sliding elements could not be used, since they would not have remained in their positions while splitting the housing. In this case the lubricant-free tribo-tape made from iglidur A160 is used instead. www.igus.com Couplings designed to API Standards R+W’s LPA series disc pack couplings are designed to meet every requirement set forth by the American Petroleum Institute (API). The double disc spacer design with keyway connection is specifically designed for API 610 centrifugal pump packages. Due to its pre-assembled, laterally removable spacer, the LPA couplings offer a safe and easy installation. The special safety catch is included to ensure that the spacer tube is not thrown from the assembly in the event of a disc pack rupture. LPA Series disc pack couplings are available in six different body sizes for torques ranging from 400 to 12,000 Nm and depending on the size, bore diameters from 23 to 140 mm. www.rw-couplings.com Compact drive now in plug-in module concept Drive technology from Beckhoff is now also available as a plug-in module concept. In combination with a broad portfolio of Beckhoff motors and planetary gear units, three new EJ7xxx EtherCAT plug-in modules enable especially compact and cost-effective drive solutions. EJ-series EtherCAT plug-in modules provide an efficient wiring solution for machines built in large and medium-sized production runs. With new motion modules, compact drive technology from Beckhoff is seamlessly integrated into a plug-in module concept, enabling extremely compact I/O and motion solutions that perfectly match customer requirements. www.beckhoff.com Noiseless water cooled torque motors Among the rotary axis drives, water cooled torque motors of the Hiwin TMRW series are extremely efficient. Synchronous servo motors are designed to operate without gears, so they achieve the highest efficiencies characterized by constant torques, maximized dynamic response, and fast speed changes. Hiwin has developed its zero-play torque motors specifically for use in machine tools. Due to its zero-contact torque transfer, they operate noiselessly and are absolutely maintenance free. In addition, the direct load coupling safeguards the high rigidity in a very compact design. www.hiwin.com New rotational speed sensors Most of the times, the standard-use rotational speed measurement device doesn’t exactly fit to the demands of end users. At this point, hydraulics suppliers need to find a customized solution. These customizations come with additional costs and some disadvantages. Having faced this situation all too often, Germany based Rheintacho’s development team came up with the new sensor range ‘the FE series’. It offers 3 different electronic versions (1-channel, 2-channel, PWM), 2 different immersion depths (18.4 mm and 32 mm) and built to protection classes IP6K9K and IP67. www.rheintacho.com MDA Technologies 3/2016

Hannover Messe abuzz with Industry 4.0 and Partner Country USA Five action-packed days and with a significant upswing in attendance: With its keynote theme of “Integrated Industry – Discover Solutions” and the USA as its official Partner Country, the 2016 edition of the world’s leading trade fair for industrial technology Hannover Messe reverberated around the world. NEWS AND MARKETS Wearing virtual reality glasses, German Chancellor Angela Merkel reached out to shake a hand in digital space, and U.S. President Barack Obama responded by shaking hers in reality. This will no doubt go down as one of the most memorable images from Hannover Messe 2016, and it also aptly portrays the close partnership shared between the two nations as they move down the road towards Industrie 4.0. “Hannover Messe 2016 has shown that the United States and Germany are equal partners in the pursuit of digitalized manufacturing and energy,” remarked Dr. Jochen Köckler, member of the Managing Board at Deutsche Messe. “In order to connect products, machines, industrial enterprises and people across countries and continents, we need to arrive at universally applicable technologies and standards. Here at this fair, the USA and Germany – along with other leading industrial nations – have sparked the dialogue needed to make that happen.” And even a quick look into the lively, jam-packed exhibition halls at Hannover Messe clearly revealed this was exactly the right place at which to be pursuing such goals. No other trade fair has ever featured so many real-world application scenarios with smart technology for the world of manufacturing, thus making Industrie 4.0 a tangible experience. The solutions on display ranged from retrofits of individual machines right on up to full production-line integration, complete with data capture and analysis in the cloud. “This marks the breakthrough for Industrie 4.0,” said Köckler. “Next on the agenda is the commercialization phase. The technology is ready to roll, and about to make its way onto the factory floor.” z MDA Technologies 3/2016
