In the vast universe of electric motors, there are a number of ways to categorize different motor types; by their power source (ac or dc), how they are constructed or assembled, or by their magnetic circuit properties. For instance, most electric motors are characterized as being either radial flux or axial flux machines, which refers […]

NanoOne 3D printer uses FAULHABER drives for alignment
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 […]
Minimizing outgassing from cleanroom equipment
Cleanrooms require minimization of friction-related particle generation. Now let’s consider another source of contamination — outgassing — and how to minimize it. Especially in cleanroom applications involving the manufacture of LEDs, optics, or glass, or the processing of silicon wafers, outgassing can damage end product. Outgassing is the desorption of vapors or gasses, either from […]
Update on designing for cleanrooms
Considering all the moving and static sources that contribute to particle generation, it’s no wonder that many designers cringe when they find out that a motion system will be operating in a cleanroom. But motion doesn’t have to be the enemy of the cleanroom. With an understanding of the particle sources and corresponding design adaptations, […]
Peripheral motion systems that complement robotics
In a previous article, we detailed example integrations of motion control and robotics. So, what about the workcells and systems surrounding the robotics in their workcells? Various automated systems can serve, move, and enhance a robot to maximize its usefulness. There are various complexity levels with these peripheral motion systems. The act of machine tending […]
Example integrations of motion control and robotics
Garnering much attention these days are industrial robotics and their integration of motion components and incorporation into workcells with other motion-based automated equipment. Such robotic workcells also feature conveyors, vision systems, and machines to automate specific tasks. So, what makes a motion system a robot or machine? In other words, what’s the distinction between motion […]
What does Safe Torque Off (STO) functionality do for servo applications?
Today’s motor drives and controls feature a bevy of safety functions. These include protecting the motor from overloads of power or current, short circuits and ground faults, and monitoring for over current conditions and over and under voltage conditions as well, and even over temperature protection to protect from excessive heat that a servo motor […]
What does today’s software for motion controllers look like?
It’s no secret that software is at the heart of motion control systems, making possible all the basic motion control functions as well as new features and functions that enhance system design and operation. Fundamentally, motion control is about positioning in three-dimensional space, which is executed by mechanical components such as motors and drives with […]
Choosing between chassis-mount and PCB-mount motion controls
Motion controllers come in many shapes and sizes to fit unique and specific application needs. From small embedded controllers that can be integrated into a servo motor along with a drive and feedback, to large stand-alone controllers attached to machines, there’s a controller to match every application need. The type of controller can usually dictate […]
How does IO-Link compare to competitive offerings for connectivity?
IO-Link is an open standard, point-to-point communication link for sensors and actuators. It’s defined by the IEC 61131-9 international standard which specifies a single-drop digital communication interface technology (SDCI, commonly referred to as IO-Link) for sensors and actuators. A typical IO-Link configuration includes an IO-Link master, which is the interface between the devices and a […]
