In everyday life and in the technical fields we often discover that certain decisions are based on “scientific data” when, in fact, they are often founded on historic conclusions that have not been challenged or re-evaluated in a long time. One such common myth is that for a stable and well-tuned drive you should match the motor’s inertia to the load inertia, which is typically done using a gearbox. Two factors lead to that conclusion: a. there is an optimization formula using the time constant of the motor and the load torque that shows that the best acceleration will be achieved if the reflected load inertia matches the rotor inertia; and b. a PID controller, which was commonly used when electric servos entered the marketplace, tend to perform best and appear to be most stable when the inertia are close or matched.
AMETEK Dynamic Fluid Solutions (AMETEK DFS) and the former Bison Gear and Engineering Corp. have combined to create a more robust, customer-centric business named Bison. The newly created Bison, a business of AMETEK, Inc., will provide a broader range of high-quality products, unparalleled customization and integration support, accelerated time to production, and global manufacturing flexibility.
Kollmorgen has announced the new AKD2G 24A drive. Designed for applications in precision multi-axis servo systems, the new single-cable optimized drive builds upon the strengths of the AKD2G portfolio including upgraded safety features, SD card backup and a graphical display with higher amperage to support more applications with higher power requirements such as conveyors and vertical lifting applications.
Allied Motion Technologies Inc., a global designer and manufacturer of precision and specialty motion, controls and power products and solutions for targeted industries and applications, announced that shareholders approved its corporate name change to Allient Inc. at a special meeting of shareholders held on August 11, 2023. The new name will be effective August 23, 2023, and at the opening of the markets that day, the company’s shares will commence trading under the new ticker ALNT on the Nasdaq.
With the introduction of their first IE5+ permanent magnet synchronous motor in 2021, Nord Drivesystems delivered a new standard of energy efficiency, variant reduction, and reduced operating costs. This Size 71 TENV smooth surface design has paved the way for additions to the IE5+ product family including ventilated designs and larger frame sizes to expand performance and versatility even further. These motors are UL/CSA certified and can be utilized across a wide range of industries and applications.
The Electrical Apparatus Service Association (EASA) honored Dennis Franklin, an Essex Brownell retiree, for the EASA Exceptional Achievement Service Award.
Almost 200 people from AD member and service provider companies across various industries and multiple countries gathered in St. Louis at the 2023 AD Finance, HR & IT Summit from July 19 to 21 for three days of cross-functional collaboration and best practice sharing.
TPS, still organized by the Turbomachinery Laboratory at Texas A&M University, will gather for the 52nd Turbomachinery and 39th Turbo annual event from September 26–28, at the George R. Brown Convention Center in Houston.
Technical sales personnel use intelligent features to select suitable motor-gearbox combinations and run calculations based on customer-specific operating data. This provides obvious added value for the customer. Service lives, safeties, and expected loads can all be determined in a short time. Maintenance of the underlying database and the use of simulation tools make it possible to quickly and easily perform technical calculations without having to rely on a central calculation department. In less than a minute, the customer is provided with a data sheet which includes reliable statements about the gearbox based on these technical calculations.
The MAXOLUTION process by SEW-Eurodrive modules in the large-scale model are intelligently networked via mobile transport and assistance systems and offer a clear insight into what tomorrow's world of adaptable production could look like. Outstanding performance can be achieved with the aid of supporting automation and future-proof material flow and logistics concepts.
