Closing the Loop around a Transverse Flux Hybrid Step Motor - August 2020

The article "Closing the Loop around a Transverse Flux Hybrid Step Motor" appeared in the August 2020 issue of Power Transmission Engineering.

Summary
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.
