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.
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.
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.
New Opportunities and Technologies Allow AC Motors to Enhance Motion Control Applications.
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.
Health monitoring or condition monitoring has been used for many years on machines and in plants where the cost of an outage is high. It allows failures to be anticipated and maintenance or repairs to be scheduled for the least loss of production, as well as avoiding unnecessary periodic maintenance.
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.

If there are two things that are in tight supply in the industry, it's time and talent. Manufacturers are always pressured to do more faster, and the industry is producing fewer experts to help them do it, so the industry's had to get crafty and find what time-cutting procedures they can.
A machine called Sub1 Reloaded solved a Rubik's Cube in 637 thousandths of a second in Munich.
Mechanical guiding systems, such as crossedroller bearings, work well for most motion control applications; however, when precision, angular repeatability, and geometric performance (runout, straightness) are critical or where submicron bearing rumble is problematic, air bearings are recommended. An air-bearing stage is a rotary or linear positioner that floats on a cushion of air, using one of several preload mechanisms, nearly eliminating mechanical contact and thus wear, friction, and hysteresis effects. Here are eight reasons why an air-bearing stage might be the right choice for your application:
