Brushless servo motors – more control for valves with linear actuators

Reprint of blog posted by Ryan Klemetson of Tolomatic on Tue, Mar 24, 2015 @ 08:03 AM

Many process industry control engineers are looking to more sophisticated motion control solutions for valve automation. That’s because there’s an ever-growing need to improve productivity, increase efficiency and minimize downtime. It’s essential that engineers be able to control the valves that regulate the flow of materials throughout a facility.

Motors deliver higher power density for compact robots

Kuka’s compact robots in the KR Agilus series are precise, agile and fast.  As agile systems, these five-axis and six-axis handling units feature short cycle times and high repeatability, particularly for pick-and-place tasks.

Synchronous servomotors from Kollmorgen’s AKM series play a major role in achieving this precision. Using collaborative co-engineering, the two companies reduced the installation volume of the motors compared to standard models.  The performance of the robots within their rated load range sets new standards for speed, cycle times and energy supply.  They can even handle unusual tasks in base and cover installation positions. Kollmorgen developed the custom motors by adapting motors from the standard AKM servomotor series.

As fast all-rounders, the robots are suitable for general industrial applications.  With a dead weight of 51 kg, the basic model can support loads up to 6 kg.  The compact robots are suitable for process automation in the packaging, electronics, food and pharmaceutical industries.

“We made a significant contribution to short cycle times and high precision by adapting our servomotors from the AKM series to Kuka’s specific needs,” said Theo Loy, sales manager at Kollmorgen.

The co-engineering partner adapted the design of the synchronous servomotors to make them fit perfectly in the joints of the robots.  That also enabled the engineers to increase the already high power density.

The objective was to find ways to implement custom performance improvements and structural assembly adaptations without sacrificing the advantages of industrial series production.  The aim was to optimize standard motors by making controlled modifications.  With custom adaptations, such as cable strain reliefs, modified bearing shells, Kuka-specific connector configurations or special drilled holes in the output shaft, the motor manufacturer could reliably maintain the majority of its standardization.  But is that still possible when the entire design geometry is fundamentally changed?

Using the smallest servomotor in the AKM series, it had to be made even thinner to fit compactly into the wrist joint of the robot.  The co-engineering process started off with 3D models and outside contours, and in the end it involved working with detailed design data.

To make things easier for the customer in the Kuka project, Kollmorgen also incorporated the engineering expertise of its own suppliers, such as a specially adapted motor brake.

“It acts as both a holding brake and an emergency brake,” said Loy. The KR Agilus is the only robot in its class that features Kuka’s Safe Operation function, which drastically simplifies human-robot interaction.

The AKM series of high-acceleration, permanent-magnet servomotors are available in 28 housing and mounting combinations.  They also feature reduced energy consumption, high control accuracy and high availability, and they are compatible with all commonly used supply voltages thanks to specifically adapted stator windings.

On Demand Webinar- DC Motor Types and Usage in Typical Applications

Selecting DC Motors Webinar

Live Webinar: DC Motor Types and Usage in Typical Applications

February 03, 2015  11:00am EST

This webinar gives you guidelines for selecting the perfect DC motor type for your application.  For example, which motor type is used in the climate control system of the Boeing Dreamliner, and for what reasons?

  • Is a brushed or a brushless design more adapted?
  • Does a flat pancake type motor fit better or should it be an elongated cylindrical one?
  • Are motors with a slotted iron core winding design the right choice, or should it be a motor with a slotless winding?

For motor selection, it is important to know the particular requirements of each application.

  • How large are torque and speed?  Are there any gears involved?
  • How is the motor operated and controlled?  What is the required precision of control?
  • What are the restrictions on size and weight?
  • How about special ambient conditions such as temperature and pressure?

Before answering these questions, the webinar starts with having a look at the properties of all kind of small DC motors with permanent magnets.

  • Which motor designs are adapted for high speed or high torque?
  • How to select motors according to torque and speed requirements
  • What are the particular advantages of brushed or brushless motors?
  • How does a slotted or slotless winding design influence motor performance?
  • What is the role of gears?

The webinar illustrates the findings on a multitude of typical application examples.

Applimotion’s LARC Motors for Large Diameter Direct Drive projects

Applimotion routinely scales its LARC motors (Linear Arc) for large diameter applications greater than 1 meter diameter. The modular nature of these motors allows them to integrate with large assemblies for scanning, imaging, and metrology applications where size requirements take priority over high torque requirements.

LARC motors come in modular pieces and will bolt into any large diameter servo motor application. The motors operate from standard brushless motor amplifiers from 24 to 300 volts. They work nicely with encoders, resolvers, or the recently introduce magnetic encoders for direct drive applications.

The LARC motors also offer very low profile design to fit into tight spaces where traditional motors have limitations. Applimotion also offers hermetically sealed magnet tracks and coil assemblies for vacuum or special environments.
