Do We Want Integrated Motors?

Posted March 20, 2008 8:03 AM

Integrated motors — where the motor, encoder, and controller are all combined in a single unit — appear to offer an attractive package that is easy to install and maintain. The market for such devices, at least in the lower power ranges, is definitely growing. But in the long term, are they stable motors, unaffected by temperature? And if one part of the combination fails, will maintenance engineers have to scrap the whole motor?

Maybe it is true that the reporter sees a growing market for these devices in the small power range of motors but there is a serious short coming to them as well.

As we design, build and test as well as service motorised stages for the laboratories microscopes and metallurgical equipment, I can easily come up with drive combination systems build from 10 or 15 different motors, 5 or 10 different encoders and at least the same amount of controllers. This is not done for just any old reason, it is done because the application requires the flexibility. What does this mean for integrated motors? I don't think they will take an important role in the drives market any day soon, too rigid, plain and simple.

I must agree with case 491 regarding the inflexibility of fully integrated motors.

The idea is a good one but it would probably not be economically feasible for one company to try to cover the market place with all of the many combinations necessary.

Perhaps a niche market or two will be found for certain combinations that may catch on and possibly offer smaller companies a more economic or smaller-package means to solve a creative drive problem.
