14 Motors and Mechatronics - Moving to a Higher Plane (September 2017)

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.

15 Transverse Magnet Flux AKA Hybrid Step Motor Driver Techniques (June 2020)

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.

16 Centralized vs. Decentralized: Choosing the Right Type of Motor Control System (August 2020)

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.

17 Closing the Loop around a Transverse Flux Hybrid Step Motor (August 2020)

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.

18 Keeping Drives Electrically Quiet: Ferrites, Shielding and Grounding (October 2020)

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.

19 Motor Sizing Unusual Loads (February 2020)

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."

20 Step vs. Servo - Selecting the Best (October 2018)

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.

22 The Gizmo Society (June 2018)

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.

45 Graco Pump Technology Solves Long-Term Pump Leaking, Dosing Issues (September 2016)

When trying to find a new bonding material dispense system, one manufacturer tested a series of pumps — all of which leaked due to the abrasiveness of the bonding material. The manufacturer also had been attempting to manage shot size manually with their previous system, and was not able to keep dispense consistent. The company searched for a system that could accurately dispense programmed shot sizes while also eliminating the leaking issues they had experienced with previous pumps. Graco provided a Check-Mate pump with SmartWare software, and the manufacturer is now able to automatically dispense shots of bonding material as small as one ounce without leaks.
