New research by market intelligence firm Interact Analysis shows that the ultra-low voltage motors market is experiencing a period of growth. By 2027 the market will be worth almost $6.5bn driven by demand from battery driven applications and a need for greater flexibility in manufacturing and logistics processes. The increased use of mobile robots is having a huge impact on the market for ultra-low voltage motors and, as a result of this, the supplier landscape will change significantly.
With the SINAMICS S210 next generation servo drive system, comprising a digitally native drive with wide range of corresponding motors and gearboxes, Siemens brings a new level of high-dynamic, motion control in mid-range operation to stand-alone and multi-axis machines. This next generation servo drive system introduces a new level of safety and security to discontinuous motion control in the mid-range segment, as well as moving, processing and positioning functions on a wide assortment of packaging, printing, labeling, pick-and-place, stacking, assembly, chip sorting and filling machines, with a special emphasis on food-and-beverage and pharmaceutical applications, owing to the availability of stainless-steel motor and planetary gearbox options.

Electric drives often need to operate under high voltages up to 800 V to provide more power and higher speeds. However, the risk of partial discharges increases at these voltages. In combination with high operating temperatures, these can locally damage the insulation and lead to machine failure. However, a good impregnation ensures not only electric insulation but also copper bonding, to mechanically strengthen the electric motor, and air gap filling, to allow a better heat transfer.
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.
