One problem I can see, from the tecnicians point of view - this puts more pieces in places that may be very inaccessable. I have built, installed and serviced industrial machines, and while it may make assembly and install a bit faster, it makes servicing the machine that much harder. It also means that the motor (withthe drive attached) also gets more expensive. Most cabinet mounted drives can detect problems and shut down to potect the drive and other components. Perhaps a motor has a bad bearing or other failure. Replace just a motor. Integrated motor and drive means that the whole package - more expensive - must be replaced.

 

You still need to run cables - raw power and control signals, so you still have to deal with cables and connections.

One limiting factor with integrated drive-motors is the availability of higher power solutions.

One significant stumbling block to single-package servo/drives is the environment in which they would be used.

In packaging machinery especially, such a combined servo/drive could be subjected to sanitary washdowns that routinely destroy components.

The IP69K standard of environmental rating was developed to describe what happens in such a washdown.  1000 psi directed jets of water at 180 degrees F is not to be brushed off.

Putting the servo drive in this environment means the cost of component includes the drive, not just the motor.

Very few servo motor manufacturers are willing to rate their motors for such extremes, let alone the drive.

Great post, Jim. I'm curious, though: The advantages of on-machine seem so obvious, it makes me wonder why we're even having the discussion. Has on-machine not been the norm up to now? If not, why not?

Excellent post.  It's easy to see that the combination of integrated drive motors, distributed controllers and I/O plus new wiring options arechanging the architecture of machines. It will be interesting to see how this plays out. I would think that more and more companies will be looking to eliminate the larger control cabinets that have been a necessary part of machinery design for a long time.  Thanks.

Rob, Thanks for your interest.  Yes, on-machine solutions are becoming more prevelent as OEMs and end users become more aware of the value of the solution. We see this technology being deployed in both new machines and plants, and also in existing installations as well.  The value in existing plants comes from that ability to add to existing machine easliy, without increasing cabinet space requirements.

Hey, Jim. Interesting article. Are the on-machine solutions getting much traction in plants yet? The customization possibilities alone seem like they would justify going in this direction. Is this development mostly applicable to greenfield installations, or, are you also seeing on-machine showing up in existing plants?

Iterative design — the cycle of prototyping, testing, analyzing, and refining a product — existed long before additive manufacturing, but it has never been as efficient and approachable as it is today with 3D printing.
People usually think of a time constant as the time it takes a first order system to change 63% of the way to the steady state value in response to a step change in the input -- it’s basically a measure of the responsiveness of the system. This is true, but in reality, time constants are often not constant. They can change just like system gains change as the environment or the geometry of the system changes.
At its core, sound is a relatively simple natural phenomenon caused by pressure pulsations or vibrations propagating through various mediums in the world around us. Studies have shown that the complete absence of sound can drive a person insane, causing them to experience hallucinations. Likewise, loud and overwhelming sound can have the same effect. This especially holds true in manufacturing and plant environments where loud noises are the norm.
The tech industry is no stranger to crowdsourcing funding for new projects, and the team at element14 are no strangers to crowdsourcing ideas for new projects through its design competitions. But what about crowdsourcing new components?
It has been common wisdom of late that anything you needed to manufacture could be made more cost-effectively on foreign shores. Following World War II, the label “Made in Japan” was as ubiquitous as is the “Made in China” version today and often had very similar -- not always positive -- connotations. Along the way, Korea, Indonesia, Malaysia, and other Pacific-rim nations have each had their turn at being the preferred low-cost alternative to manufacturing here in the US.
