Drive solutions with explosion protection from Nord The company, Nord drive systems, a developer and manufacturer of drive technology supplies explosion-proof motors worldwide. Drawing on an extensive SAP-managed modular product range, the German manufacturer is able to quickly and comfortably configure drives for hazardous areas with absolute safety. Depending on the zone – whether 1 or 2 for gas, or 21 or 22 for dust atmospheres – optional external fans, backstops, and brakes are fitted as required to suit the application. Vector controlled operation with a frequency inverter is also possible on request. The motors are suitable for operation at ambient temperatures up to +60 °C. In addition, the drive manufacturer supplies gas and dust-explosion-proof gear units. These comply with EN 13463 and feature ignition protection type Ex-c (constructional safety). The motor can often be mounted directly on the gear unit. NORD, a certified manufacturer since 2003, has immense experience in explosion protection for drive technology. The current products meet the 2014/34/EU Directive, which came into effect on 20 th April, 2016, and the provisions of IECEx. www.nord.com Linear brakes for vertical axes Mayr power transmission, the specialist in braking technology has designed a fluid-free electromagnetic version of the Roba-linearstop brakes. In case of power failure or emergency stop, these brakes hold the axes reliably in any position, protecting both people and machines from injury or damage. For applications, in which no compressors or compressed air/oil hydraulics are wanted, for example in the medical technology, food or pharmaceutical processing, mayr’s electromagnetic version of roba-linearstop offers a clean braking solution. For the electromagnetic version, expensive components of the braking system such as direction control valves and quick release valves are no longer required. The brake designs in this series work in accordance with the fail-safe principle; this means, they are closed in de-energised condition and the braking force is generated through the pressure springs. Before a brake leaves the company’s factory in Mauerstetten, the required force is adjusted to an appropriately safe setting. This value is checked, recorded and assigned to every serial number. The electronic database, in which the measurement values are archived together with the associated product serial numbers, guarantees 100 % traceability. www.mayr.com Online platform for customizing high-end drives within minutes Choosing the right DC motor has become more crucial than ever especially in situations with time constraint. With Maxon motor’s online configurator the process of selecting the drives and evaluating various possibilities becomes quick and convenient. The online platform has thousands of drive options to choose from. Brushed and brushless DC motors with diameters from 8 to 35 mm form the basis of the offering. Maxon has recently expanded significantly its range of ECX drives, as a result ECX Speed drives are now available in a variety of sizes, including the high-power versions. Apart from ECX drives also on offer are the suitable planetary gearheads (GPX Speed). All of the drive’s interfaces can be adapted at will in the online configurator: shafts, flanges, electrical connections, etc. This gives users a whole new range of possibilities to put together a customized high-end drive including the gearheads and encoder in only a few minutes. The electronic data goes directly to Maxon motor’s production facilities, where the drives are put together in automated processes. No later than 11 days after placing the order, will the drive leave Maxon’s factory in Switzerland. www.maxonmotor.com Smart actuators for intelligent positioning PRODUCT NEWS The latest Siko Ethernet and fieldbus equipped actuators AG25 and AG26 offer a systematic answer for positioning machine axes smartly and automatically. Despite their high functionality and performance, Siko’s actuators require space not more than a 0.33 liter beverage can (AG25). Thus, the actuators are ideally suited for machines that have space limitations. The AG26 is built slightly larger but also has more power – up to 13 Nm – despite its ultracompact frame size. The drives have a hollow shaft with a clamping ring for easy installation. High-precision multi-turn absolute encoder that detects the position of the drive shaft and the rotation of the shaft in the de-energized state of the actuator is integrated in the actuator. In addition to the Profibus and CAN data interfaces, Siko has also implemented the most common industrial Ethernet fieldbus interfaces into the actuators: Profinet, EthernetIP, EtherCAT and Powerlink. The actuators AG25 and AG26 can be configured and parameters can be set directly via the master PLC. 4 The actuators are available up to protection class IP65, which is also guaranteed during the traverse operation. www.siko-global.com MDA Technologies 5/2016

Magnetic direct drive for high velocity industrial scanning applications Magnetic direct drives offer less friction, play, and therefore more precision over the classical motorized, spindle-based drives. For high-velocity industrial scanning applications, the company Physik Instrumente, a global player for precision positioning technology supplies the drive and positioning systems which make use of magnetic direct drives. With its friction-free magnetic drives PIMag series offers linear travels ranging from 5 to 20 mm, which reach the highest velocities up to 250 mm/s and scanning frequencies of some 10 Hz. These drives are particularly suitable for applications that require 24/7 operation, for example, in metrology, photonics, for image stabilization systems, in semiconductor and flatscreen inspection. Due to its crossed roller guides, the linear stage attains a travel accuracy of 1 µm. Its optical linear encoder allows a reliable position control and repeatability of ±500 nm. The sensor resolution is less than 10 nm; the minimum incremental motion is 20 nm. This direct drive series is also only 80 mm in width and 26 mm in height. www.pi.ws Optical encoder with high precision Hengstler’s ‘Acuro-AX73’ series of optical encoders carries international certification for gas and dust explo sion protection which makes it suitable for use in hazardous environments. Apart from safety, precision is another beneficial characteristic of the Acuro AX73. The optical scanning system provides a highly accurate, 22-bit resolution sensor signal for areas wherever precision or smooth speed regulation is necessary. However, despite its accuracy, the encoder is of robust design, with impressive resistance to shock, vibration and external magnetic fields. In addition, the unit provides users with IP67 protection class rating for the stainless steel housing, with an ambient temperature range of -40 to +70 °C. AX73 has a housing diameter of 76 mm, which proves valuable to system designers seeking space-saving solutions. Available immediately, the AX73 can be ordered with SSI, BiSS-B, BiSS-C and Profibus interfaces. This advanced optical encoder offers significant cost and time savings during installation. The introduction of the AX73 completes the company’s comprehensive family of ATEX-rated absolute rotary encoders, both optical and magnetic.
