Nice to see progress being made in terms of energy efficiency. Beyond their so-called "green" aspects, does this new crop of linear motor technology offer any other advances compared to traditional offerings?

Beth: One of the big differences is the linear motor's positioining accuracy. The numbers vary pretty widely, but several of the linear motor makers I talked to said they could resolve their accuracy down to the low-micron level. Some even claim to get it into the nanometer level. That's a far cry from what we saw in linear motors a decade ago.

It can actually be traced to less than a decade ago.  This time frame though was the start of when the accuracy levels were starting to improve.  

 

I know that our company once looked at the possibility of implementing an automatic solution for one of our tests, the problem is there was nothing accurate enough to allow us to achieve the resolution we needed.  Now with the accuracy bar being lowered, pun intended, I think it might be time for us to revisit our initial designs.

The positional accuracy will really benefit biomedical applications.

This accuracy hitherto not seen in linear motors will make it an ideal candidate as a solution for some of the complex problems in surgical robots
