What makes a bus based Motion Controller deterministic?   What are the three types of Step Motors?   What is the difference between an Absolute Encoder and a Resolver? These questions (and many more) are quickly answered Motion Control Technology Primer...

Maxon’s new IDX compact integrated servo gearmotor + drive. A powerful brushless EC-i motor & EPOS4 positioning controller.

Combines a powerful, brushless EC-i motor and an EPOS4 positioning controller.

The DMC-21x5 is the latest addition to the Econo family and is an easy upgrade path from the long running DMC-21x3 series.

Electronic gearing in motion control allows for a slave axis to follow a master axis with a programatically set gear ratio.  There are certain applications that obviously lend to an electronic gearing solution, but there are some challenging applications where the functionality of electronic gearing can greatly simplify a solution in a manner that may not seem obvious at first.  This series of three papers will discuss how electronic gearing can provide simple solutions to different motion control challenges...

There are many challenges when designing a motion control system. One challenge that can overwhelm many engineers is nonlinear mechanics. These mechanics can make tuning a motion control system difficult. At Galil, we pride ourselves in being able to provide intuitive solutions for these nonlinear or unorthodox mechanics. This webinar will discuss six examples of applications with nonlinear mechanics, their inherent challenges, and the tools/solutions to address these challenges.
Below are the six examples of applications with nonlinear mechanics:

1. High-friction axis
2. Mechanics with backlash
3. Servo axis involving a spring
4. Axis exposed to large and unpredictable outside forces
5. Mechanics where inertia varies with position
6. Hydraulic axis

Check out the latest publication from the maxon academy, Motion Control for Newbies, a practical introduction to motion control.  132 pages.
The basic approach of this textbook, like many, is a practical and experimental one; however, it is reversed from most.  Instead of first explaining the theory of motion control and then applying it to specific examples, here we will start with hands-on experimenting on a real maxon EPOS2 P positioning control system by means of the EPOS Studio ...

In case you missed the May 13th Galil Motion Control Webinar -The Evolution of Ethernet in Motion and I/O Control, a recorded version can be viewed at the following link-

This webinar focuses on the evolution of Ethernet-based motion control and why Ethernet is the protocol of choice for industrial and automation applications.  The webinar discusses the differences of Ethernet in a distributed vs centralized architecture as well as the trade off in performance.  Topics include deterministic and non-deterministic Ethernet communication protocols and what applications they are best suited for.

Achieve precise positioning and high torque at slow speeds without investing in a servo motor, thanks to Galil's integrated high-power (8 Amps continuous), 2-phase drive for closed-loop step motor control. This innovative solution blends the economic advantages of step motors with the accuracy typically associated with servo motors, presenting a viable option for both mechanical and electrical engineers in a range of applications.

Traditionally, automation applications have utilized either step motors, known for open-loop operation, cost-effectiveness, and suitability for high torque, slow-speed applications with moderate positional accuracy, or servo motors, which offer precision control and smooth motion at both high and low speeds through incremental or absolute feedback systems. Servo motors usually require more sophisticated control systems incorporating features like PID filters, making them pricier and more complex to stabilize compared to step motors.
