The MELSERVO-J5 portfolio of servomotors and amplifiers has been expanded to include two new servo types, additional “high-speed” motor models, and a number of new features and functions for enhanced capabilities and unparalleled performance compared to previous generations.

ABB is set to feature high-efficiency motor solutions during WEFTEC in Chicago, Illinois, USA, on October 2-4. Attendees are invited to visit Booth 2348 to learn from ABB experts about the company’s innovative products and services and the essential solutions they provide for water management and wastewater treatment. ABB’s Global Segment Manager Todd Huston and Global Product Marketing Manager Stefanie Casimir welcome visitors at the booth to discuss these products and their benefits to customers.

ABB will be featuring its high-efficiency NEMA motors solutions at Turbomachinery & Pump Symposia on September 25 – 28 in Houston. Attendees are invited to visit Booth #2835 to learn from experts how ABB’s innovative products and services provide essential solutions for energy saving, facility comfort, productivity and more. ABB’s Global Segment Manager Todd Huston and Account Manager Kirk Franz will be available at the booth to discuss the products and the product benefits.

ZF has developed an electric motor which does not require magnets. In contrast to the magnet-free concepts of so-called separately excited synchronous motors (SESM) already available today, ZF’s I2SM (In-Rotor Inductive-Excited Synchronous Motor) transmits the energy for the magnetic field via an inductive exciter inside the rotor shaft. This makes the motor uniquely compact with maximum power and torque density.

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.

Kollmorgen recently announced the launch of Kollmorgen Express Delivery. This new designation identifies highly popular motion products — including some of the most requested configurations and options — that Kollmorgen is ready to deliver within an accelerated timeframe. Machine builders have always benefited from Kollmorgen’s wide range of standard product configurations, features and options. This broad portfolio serves the unique needs of many diverse industries and applications but can create challenges for rapid delivery, especially when material supplies are constrained.

The 2023 EASA Convention, June 25-27, at the Gaylord National Resort & Convention Center in National Harbor, MD. EASA (https://easa.com/convention) supports companies involved in the service and sale of electric motors, pumps, drives, controls, gearboxes and other rotating machinery. Highlights include synchronous motors, machine reliability, leadership, sustainability, EASA's 90th birthday bash, motor maintenance, pump repair, supply chain issues and more.

Visitors to EASA in June will get a chance to see some of the highest efficiency electric motors available on the market when they stop by the Nidec Motor Corporation Booth (#613). Nidec’s “Super Premium” and above variable frequency drive (VFD) motors and all-in-one, integrated motors and controls are leading the industry with efficiency ratings of IE 4 and IE 5 for remarkable energy savings compared to traditional single speed motors.  

SEW-Eurodrive is expanding its comprehensive portfolio to include new motors for purely inverter operation. The synchronous motors of the DR2C.. series satisfy the highest standard-based efficiency class IE5 for adjustable-speed electric motors. This makes them yet another sustainable and energy-saving motor variant. 

ABB recently announced it has completed its acquisition of the Siemens low voltage NEMA motor business. The transaction was originally announced August 11, 2022, and financial terms of the transaction were not disclosed. The business employs around 600 people and generated revenues of approximately $63 million in 2021.
