Motion control systems often combine high power drive signals in close proximity (or even within the same cable) with lower level signals, like encoders. You will often see ferrite beads added around cables; their effectiveness in minimizing noise is greatly affected by how they are deployed. This involves which signals are grouped, what are the drive characteristics, and how shielding and grounding are handled in the system.
Are you looking for one simple formula to help you choose between centralized and decentralized motor control? Unfortunately, such a formula does not exist. However, evaluating the overall size of the system, comparing labor and material costs, and maintaining flexibility can help guide engineers in the right direction.
Transverse magnetic flux motors -- also known as step motors -- become Hybrid Servos when you operate them closed loop. This is the same transformation that happens between running a 3-phase synchronous motor from line voltage as opposed to running it closed loop as a brushless servo. In the case of hybrid motors, there are many degrees of what is advertised as "closed loop," and thus significant differences in the performance improvements seen.
The transverse flux permanent magnet motor -- also known as a hybrid step motor or hybrid servo motor -- has a wide range of performances, depending upon how you drive these motors, and whether you operate them in open loop or one of the many variants of closed loop methods you use. In this third installment we will cover some of the many ways to drive these motors, as well as how these choices affect the performance of these motors.
One of the fun parts of the motion industry is involvement in popular movies! Motor specifications can be a bit rough: "I need to spin a 120-pound actor (and chair) 180 degrees in one-half second. He will be sitting up-right."
Industrial mainstay adapts to remain relevant in a 4.0 world

Over the many years, there have been many technical papers and articles about which motor is the best. The short and sweet answer is - let's talk about the application. More recently a number of papers and articles have appeared that compared each motor's advantages and disadvantages in generic or specific terms. Many times, the methods used to drive and control these motors are not completely described due to the many control schemes available for use. A few articles focus on just the open loop step motor and the closed loop servo motor advantages and disadvantages in a laundry list format. This article is attempting to "drill down" into the reasons why and to describe how it is done.
It is hard these days to find any device that is not IoT-compatible or WiFi-connected. I recently had a new well pump installed that requires an iPhone for setup, which makes it hard for me to check or change the setup since I do not own an iPhone. In Olden Times, you had potentiometers or RS-232 connections - and that was fine.
This is an article about motors - preventive motor maintenance, actually. And something else - mechatronics. In today's high-tech manufacturing and industrial use environments, it is near impossible to talk about equally complex motor maintenance and repair-or-replace protocols without it.

For a 5-megawatt wind turbine prototype, aerodyn employs the latest control and software technologies, including a comprehensive PC-based control solution and the new modular TwinCAT Wind Framework. The TwinCAT Wind Framework features the latest software engineering and Big Data applications to extend current Industry 4.0 concepts to the wind energy industry. The modular software supports, for example, the direct provision of sensor data to the operatorâ™s database, and in general enables the easy adaption of the wind turbine operation management to future requirements.
With advances in modern technology reducing demand for envelopes, manufacturers are finding it increasingly hard to justify investment.

Enhancing production with â” and for â” less is the standing order in todayâ™s manufacturing world. Speeding up production while at the same time looking for ways, to cut, for example, energy costs, is a tricky equation with no single answer; where and how management goes about achieving that can take several paths.
What was once targeted specifically toward the machine tool and metalworking industries, IMTS 2014 in Chicago spent a great deal of time and resources on automation, controls, mechanical components, self-diagnostics and an increase in productivity on the shop floor.

In the past decade, electrohydraulic braking systems--including ABS and traction control--have grown increasingly popular, due largely to the vehicle design flexibility and performance advantages they offer. The industry has seen several other instances of intelligent machine controls, unrelated to braking, over the years as well. But what all of these technologies have typically had in common is that theyâ™ve existed as standalone, point-to-point functions that have not been integrated together. The present and future of braking is all about taking the next logical step--getting fully connected and finding ways to embed intelligence throughout a machine.

Maximizing packaging machine productivity and performance is imperative to success and is driving OEMs to adopt and invest in the latest technologies that can meet their customersâ™ challenges. At the forefront of these performance-driven technologies is an integrated control system—or programmable automation controller (PAC)—and latest-generation motion solutions.
This paper introduces the basic fundamentals of proportional-integral-derivative (PID) control theory and the characteristics of each of the PID control loops.
One of the driving forces behind the industrial revolution was the inventionâ”more than a century agoâ”of the electric motor. Its widespread use for all kinds of mechanical motion has made life simpler and has ultimately aided the advancement of humankind. And the advent of the inverter that facilitated speed and torque control of AC motors has propelled the use of electric motors to new realms that were inconceivable just a mere 30 years ago. Advances in power semiconductorsâ”along with digital controlsâ”have enabled realization of motor drives that are robust and can control position and speed to a high degree of precision. The use of AC motor drives has also resulted in energy savings and improved system efficiency. This paper reviews the development and application of inverter technology to AC motor drives and presents a vision for motor drive technology.
