I was going to pester the group for exactly the table I found below--aww by
myself, iffin you can imagine dat... Armaggeddon must be near....

http://www.electricmotorwarehouse.co...frame_info.htm

Anyways, I think this might remove *some* of the mystery of motor
replacement, and expand one's options, at least dimension-wise, which in one
of my cases is pretty important.

Yeah, I outdid myself!!

What a handy thing to have! You'll proly find the Baldor pdf more useful
than the table that comes up below--you'll see it. If you can stand
pdf's.... In this case, it is worth it.

For example, did you know that the *shaft diameter* is in fact part of the
"frame specification"??? As are keyway dims, etc.!

In my VFD query, someone mentioned that I might could do with a 145T frame
(143T is oem).
They were exactly correct, and in fact it is the ONLY substitutable frame
possible, in this case, unless I want to bush up/down shafts, etc.

Not clear, tho, whether the "cast iron-finned" spec is a part of this, or
internal/external cooling/totally enclosed, etc. I think these might be
add'l specs, but I'm not sure.
Anyone know?

Anyway, for anyone replacing motors, this should be a big help.

The motor construction, materials, etc., are not part of
the NEMA frame spec. It only insures that, for example, any
143T motor will bolt up in place of another 143T. In other
words, it's a dimensional spec, not a guarantee that the
motors are functionally compatible.

Interesting , thanks for the link although it seems to refer to
'regular' motors and doesn't cover the NEMA 23 and 34 stepper motor
standards which I am currently interested in.

Thanks anyway ;-).

Add those specs to what I googled on: electric motors frame guide
no quotes; or put in various quotes to narrow things down.
The above link was 3rd on the list.

Oh yeah, the new Graingers catalog also has such a chart. Proly older cats
as well, in the beginning of the motors section. Also some other info.
