What CERTAINLY must have been called out by now is the complete disconnect between "Electrical code issues" and the IEEE. Having been a member of the IEEE, the IAEI, the IBEW, and eng-tips for what I would consider various long times, I can say and will defend (if need be) that the the IEEE is...
I've been running into projects recently that are using a very poor, but "name brand" strut. I'll not mention the manufacturers name, but my post is intended to warn others of making similar poor selections.
Because a manufacturer makes some excellent products in one realm, they should not be...
I'd like to encourage / beg some of our regulars and MVPs to post some whitepapers!
Electricpete has some good stuff as links in some replies on threads. I know there are plenty others out there.
If we don't get a bit of a collection going here we're all stuck with having to join various...
I stumbled across the Wiki on "Lynch motor". I won't attach or quote it, but I'm wondering what it really is that puts it in it's own classification. At least other than the unique claims to be the next, greatest thing and is wonderful for E-vehicles.....

I believe it could...
Oh-boy, What exactly IS CC-Link (and I don't mean what their website attempts to say)?
Isn't it really just a pseudo-standard for Mitsubishi's communication link between a melsec PLC CPU and a remote I/O rack?
Is it very close to any other networks?
Almost any insights would be helpful.
Bodine's E-Torq motor documentation speaks of "Faraday motors", but this motor being a Lorentz based design. My brief study of H.A. Lorentz's work essentially leads me to believe that Bodine is in effect claiming their design defies our understanding of electicity and magnetism, and essentially...
coming over from the thread about 600v PM motor,,, I'm looking for material - on the web primarily, about brushless PM motors being used as variable speed motors.
I'm fighting a couple brakemotors, made in an eastern asia/pacific rim country, and with little documentation available,,, none in any language I can understand. I've worked with/on quite a few motor brakes in the past on NEMA motors, but my memory of the details is poor. Anyone have any good...
A follow-up on thread242-141768.
I did in fact leave the facility and company I worked at, where unsafe machine controls were a concern of mine, and just in time.
A man fell into one of these machines on a night shift a few months ago (about 6 mo after I left). He was killed, and most of his...
Particularly regarding NFPA 70E, NFPA 79, inspectors.
This is actually a cross-post, but I know there's plenty of expertise in this forum. There are several regulars here in particular that I hold in high regard. Any insights would be appreciated.

Please let us all know how this works out for you! and don't forget faq731-376
There are a few archived threads regarding some NFPA 70E stuff, but I'm looking for more insight(s).
I have an instance where a 1 VERY dangerous machine, and 3 more not quite as man-eating machines are being used. NFPA 70 (NEC) is being violated by no in-sight or readily accessible or labeled...
