Less is More – That Applies to Drives for Winders, too

Ratingen, 12 May 2011 – With Kollmorgen’s Cartridge Direct Drive Rotary™ (CDDR) motors, Kollmorgen offers a rotary direct drive system solution that allows OEMS (Original Equipment Manufacturers) and end-users of packaging machines to achieve significant competitive advantages. Consistently, the system enables 20% higher machine uptime and 30% more throughput than motor-gear solutions. At the same time, it features 40% fewer components and on average, generates a 20% lower service cost. Significant improvements can also be achieved in acceleration and positioning accuracy, reliability, smooth running, servo drive properties, energy efficiency, and noise development. Over the entire life cycle, the Cartridge DDR motor can generate cost savings of up to 50%.

The Cartridge DDR motor offers numerous advantages, not only compared to motor-gear solutions, but also in comparison with other rotary direct drives with no housing. Since they represent a standard solution – which is also extremely variable and flexibly adaptable – no individual components have to be modified to each other and integrated in the development and production of the machine. In addition, no additional costs are incurred which are typical of other special solutions, given their significant time-consuming and labor-intensive assembly and more expensive test phase.. At the same time, the risk of technical incalculability is also lowered.

Combining Cartridge DDR motor with Kollmorgen’s versatile AKD™ servo drive can improve the machine performance even further. The motor data stored in the AKD as well as sophisticated control algorithms permit greater precision, optimized energy usage and more productivity. Due to preconfigured motor data and feedback device data, the installation and commissioning is further facilitated and accelerated.

A sophisticated modular system enables Kollmorgen to precisely tailor the Cartridge DDR to customer requirements. Five frame sizes (108 to 350 mm) , 17 different lengths and 52 standard windings are available, while the nominal torque values range from 4 to 510 Nm, reaching a peak torque of up to 1,090 Nm, and speeds of up to 1,500 RPM. Kollmorgen supports its customers with numerous analysis and design tools and comprehensive consultation through co-engineering, as needed, in building the perfect Cartridge DDR solution for the respective application.

Besides packaging machines, the Cartridge DDR motors are used in numerous other applications. Existing applications include material punching and forming, printing molding and sealing. Over a time period of five years, the use of Cartridge DDR motors can reduce operating costs by increasing uptime, reducing maintenance, reducing energy comsumption, increasing throughput by approximately 7,000 Euro.
