I get my ME from the local newsagent in Sydney, so always a bit late.
The referenced article was eagerly read as I spent my career in heavy variable speed drives, initially servicing thyristor drives and finishing with applying and using VFDs.
But, the referenced article is either: - a spoof initiated by the editor on the reader, - a spoof initiated by an author on the editor, and thus also on the reader, - or an abominably written document mauled beyond recognition by the editorial and style conformance systems.
Where can I find a discussion on this article ? - there must be something out there by now.
I checked the date, but it is not April the 1st. A puzzled John.
Why not ask on the Model Engineer forum, the editor may well see it as well as the author and I'm sure others will comment if it has not already been discussed in which case you may get pointet towards the relevant thread.
