With advances in modern technology reducing demand for envelopes, manufacturers are finding it increasingly hard to justify investment.
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.
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.
Enhancing production with âÂ€” and for âÂ€” less is the standing order in todayâÂ€™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.
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."
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.

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 operatorâÂ€™s database, and in general enables the easy adaption of the wind turbine operation management to future requirements.
rotary-type blowers? Examples: for motor KW; RPM; temperature; pressure production; lifetime; etc. In other words, how do I choose between belts or couplings?
While the basic design of iron and coke blast furnaces is centuries old, today's steel makers are looking for innovative ways to produce molten iron with increased production and efficiency
This paper introduces the basic fundamentals of proportional-integral-derivative (PID) control theory and the characteristics of each of the PID control loops.
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 customersâÂ€™ challenges. At the forefront of these performance-driven technologies is an integrated control system—or programmable automation controller (PAC)—and latest-generation motion solutions.
a custom hydraulic brake system from Mico Inc. aid in the development of specialized material handling equipment.
The latest tools and techologies in power transmission, motion control and related components.
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.
Filtering is needed in various control and communication Applications.
Let's start with why field weakening is useful: it produces a wider speed range for a motor - with a constant torque at lower speeds and an almost constant power capability at higher speeds.

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.
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.

JBT Corporation benefits from Kollmorgen Hygienic motor design in food and beverage application.
Approximately one quarter of all servo motors around the world require some type of gear reduction in their applications. From large satellite dishes to precision medical devices, gearboxes boost torque and reduce speed for servos in order for them to be sized more efficiently. While gearbox fundamentals haven't changed much over the past 20 years, their effectiveness has improved significantly, driven mostly by the need to accommodate advancements in servo technology.
TodayâÂ€™s newspaper advertisers demand vibrant, attractive color printing, and newspaper printers are constantly looking for methods to improve printing processes to meet these demands. When it comes to improving the printing process, the key component is to choose the right printing press.
