UpNano’s NanoOne 3D printer uses two-photon lithography to produce micro- and nanoscale structures for applications such as microfluidics and medical research. Because printing accuracy depends on precise substrate alignment, the system uses three compact FAULHABER motors to position the substrate during fabrication. The printed structures are not visible to the naked eye and require scanning […]
DC Motors
What’s really the difference between a dc servo and an ac servo system?
This article provides a history and general guidance on the capabilities of different ac and dc servo technologies. By Hurley Gill • Senior applications and systems engineer | Kollmorgen Many of today’s industrial and commercial applications — whether controlling a specific operation or just some specific motion — require electric motors. These ac and dc […]
New brushless slotless motor for industrial power tools from Portescap
Portescap’s latest innovation for the industrial power tools market is the 40EC-Pro PowerTool (PT) brushless slotless motor. This motor comes in two lengths, the 40EC-Pro PT 44 at 44 mm and the 40EC-Pro PT 55 at 55 mm. Notably, the 40EC-Pro PT 55 is Portescap’s first motor to feature an integrated fan, which actively cools […]

New flat brushless dc motor features integrated encoder
The new DF45 brushless dc motors from Nanotec are now available with an integrated encoder. The new flat motors have a diameter of only 45 mm and, owing to their extremely compact design, are suitable for applications that require precise positioning in confined spaces. The 2-channel encoder has a resolution of 1,024 CPR and provides […]
AMETEK Haydon Kerk Pittman introduces new 57-mm size in IDEA Motor series
AMETEK Haydon Kerk Pittman (HKP), a business unit of AMETEK, has released a new size in its IDEA Motor series of brushless dc motors: 57 mm. This EC057B joins the 42-mm EC042B product introduced in 2019 and enhances a line of motors with integrated, programmable drives. The IDEA Motor combines a precision brushless servo motor […]
Which types of DC motors can be used as servo motors? (And a refresher on DC motor technologies)
Servo motors are used in applications where precise control of position, speed, or torque is required. But many different types of motors can be considered servo motors — the defining feature of a servo motor is that it incorporates or reads feedback in a closed-loop system. In fact, although many servo applications use synchronous AC motors, […]
