A look at several Two-Phase Hybrid Step Motors and their dominant error sources, and comment on how the errors are overcome by true servo operation of these motors.

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.

This is the first of a series of articles on permanent magnet transverse magnetic flux motors - AKA step motors. These articles will be covering the development history and the various drive technologies used with these motors - both open and closed loop.

Lower-cost motor technologies exist that can be an attractive alternative to neo-based BL PM motors - and are not subject to unpredictable supply chains

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.

How would you compare the efficiency and capabilities of hybrid stepper motor actuators vs. can stack stepper motor actuators?

Enhancing production with — and for — less is the standing order in today’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.
