Motor kits enable compact size and better performance

design phase. That way working in close partnership, the main elements, of the ‘stator’ and ‘rotor’ will be selected to seamlessly integrate with the aim from the outset of reducing complexity. The ‘kit’ servo motor approach is said to offer many

advantages over traditional technologies, such as: - Maximum energy efficiency as all couplings and


arker, a global leader in motion and control technologies, has built up considerable first-

hand experience over many years about the complex topic of how to integrate servomotor kits into machines, especially when working in conjunction with demanding OEM’s. Now, Parker is looking to share this wealth experience with the machine building community, in particular those seeking unrivalled precision, reliability and robustness in comparison with conventional machine construction techniques. When it comes to selection of the right servo

motors, Parker has re-engineered the process to deliver high performance servo motor kits that can be skillfully be integrated directly into today’s sophisticated machines. This approach gives a variety of benefits to the customer, including improved ROI, increased design flexibility, end-user energy savings, compact dimensions, overall machine performance improvements and, not to be forgotten, more secure intellectual property. Usually design engineers have used standard servomotor solutions, which frequently need to be adapted to the machine’s mechanical configuration using couplings.

Traditionally the construction of the machine starts

with the functional definition of the system being specified by the mechanical design department. In turn this is followed by the search for standard motorisation, often which must be modified to the mechanical system with various couplings, gearboxes, flanges etc. Now Parker engineers like to get involved as early as possible in the machine

mechanical components (pulleys, belts, gearboxes etc.) usually necessary for the motor adaptation are not required.

- Reduced footprint and total weight. - Mechanical and electrical adaptation to the corresponding application requirements. - Reduced maintenance thanks to the mechanical

simplification of the machine. - Quiet operation especially when water-cooled solutions are used. The components for Parker’s kits come from its proven, high performance, standard motor platform that ensures quick availability. The parts are already used in global sectors such as energy, medical, machine tools and industrial machinery. A complete range of products is available to meet the design needs of many different mechanical systems. The NK kit series, for example, is available with a torque range up to 42 Nm, while for more demanding applications the NKW water-cooled series covers the range up to 72 Nm (for speeds up to 15,000 rpm). In addition, Parker’s K series is available for low voltage applications. Several sensor types can be used with the motor kits, depending on application requirements such as robustness, resolution and accuracy. Parker’s unequalled experience and know-how in the design, manufacture and integration of frameless servomotors means that the company can also offer other high speed solutions with its HKW and SKW series, as well as the high torque TKW series. In addition, Parker is also happy to develop highly customised solutions upon request.

Ensuring the interoperability of motion control T

o ensure that everything runs smoothly in drive technology, clean interfaces between all components involved are required. The long-established certification process of PI (PROFIBUS & PROFINET

International) ensures that users around the world can rely on uniform and interoperable communication and application interfaces. To further ensure the interoperability of drive and motion control applications, certification of products with the Encoder profile are now available. The Encoder profile belongs to the application profile class and, together with the PROFIdrive profile, defines uniform interoperable application interfaces for the different fields of use of drive technology and motion control based on PROFINET and PROFIBUS. For a fully-automatic sequence and an automatic evaluation of test cases, the proven PROFIdrive profile tester will be used for the encoder certification test. A special test script set was developed for encoder certification, which is available for the latest profile tester version and controls the test sequence and the test evaluation for encoder devices in the test system. This increases the quality, reduces the test effort, and keeps certification costs low. Like the PROFINET tester, the PROFIdrive profile tester with the encoder test scripts is also available to PI members as a free download. Encoder manufacturers thus have the opportunity to use the test system during development.
