Modular devices and systems are a trend that's going to continue to grow.

Thanks for this real-world perspective, btwolfe. I think this will be important given the trend of motor and motion control in the automation environment.

Thanks for the link, Al. I will take a look at that article.

Elizabeth, Here is link to article I worked on earlier this year on this same topic. Interesting technology.

Several suppliers do offer IP67 rated motor-drives, which is often the level of protection used in packaging.  Obviously the specifics of the application are vital but many of these units are finding their way into packaging capitalizing on their ability to provide distributed control.

Protecting the drive electronics is no harder than protecting the motors. Properly designed motor controls can withstand the same harsh enviroments as the motors they control, perhaps even more so given that the electronics can be fully sealed since they have no moving parts. I would argue that the modular motor/control set is easier to replace since it has fewer connections with only power and comm, whereas a separate controller must also route sensor wiring. I have been designing and using modular motor control electronics for years and am always pleased with how clean the connectivity is in the final product.

That's an interesting perspective, TJ, I suppose you are right. Is there a solution to protecting the drives?

Charles, if you're talking about packaging machinery, at the least on a food packaging floor, I would never touch these.

Palletizers, cartoners, maybe.  But not applications that would expose them to wash-down, water, etc.

I agree, TJ. I would guess that packaging has a lot to do with this trend.

Drive-on-motor has been tried several times, and is making a resurgence again.  Depending on how the drive and motor are integrated, failure of one can be twice as costly as when the drive and motor are more traditionally separated.

Putting the drive out in a production environment invites this sort of failure.  The production environment may be extremely hot, or extremely dirty, or extremely wet.  Any of these may lead to that more costly failure.

Finally, there's the amount of space needed for the drive when piggy-backed to the motor.  Many times the space inside a machine is sufficient for the motor only (and sometimes, not even then).
