Re: automation and analog.
So anything that would make setup of systems easier will be good. And any changes in the way the products are designed/circuit subsystems are implemented will probably (1) take some of the cost out and (2) lead to easier setup and programmability of the equipment.

automation and analog.
I use analog all over the shop floor in the metal stamping industry. in die running 40 plus strokes a min measuring Hieght, thickness of parts +-.005". plus in die force measurements,leaktesting, its get using Plc's to control and so the Hmi can have easy set ups for operators/toolmakers. Changes for me is making some dies work oversea's with different elect. controls. i have came up with some was to do it there with using different analog to digital controler but makes setup harder on the end user.

Re: Variable frequency drive
Certainly the induction motor is pretty much the same now as it was decades ago. There have been improvements in manufacturing techniques and materials, so that has helped.

But we're more concerned here about the use of new technology in the controllers for the motors, rather than the motors.

Yes, theoretically it seems to be a good idea. However, I do not know why that is not done in practice. Motor has not advanced for decades and it is time we find a way to change it.

Re: Variable frequency drive
I would agree. That's the sort of equipment Rockwell is working on (I used to work with them at my previous job) and they certainly know about VFDs for induction motors. So yes, since the circuitry takes up lots of board real estate and is not especially easy to design, anything done to integrate that functionality down into the ICs will surely help designers.

Variable frequency drive
Hi Brad. According to Wikipedia there are huge savings available by upgrading motor control to Variable Frequency Drives. This seems like a good area for analog integration. Any thoughts on this?
