free 7.5hp motor - probable weight? ball bearing or bushings? (fourpix)
 

I've been offered a free electric motor, "brooks" brand, apparently made
in England. I later intend to use it in a rotary converter project.
though it's here IN my town, making contact with the guy is "pretty near
impossible". presently await his call, or reply, which could be a few
more weeks (with luck).

meanwhile, here's the -only- four photos i have of it, the guy provided
these

meanwhile, guys, hopefully YOU can tell me:

how much this thing MIGHT weight, roughly? or, alternately, your best
guess would be 'more than I know now. question has mostly do do with
loading considerations - what I'd need to bring when I go get it. I
found two 'similar-looking' motors on ebay (or somewhere), one at 185
lbs, another at 196 lbs. that sound about right?

also, do the two grease fittings indicate this particular motor has
bushings 'instead of' ball bearings?

OR do the grease fittings near the endbells indicate -nothing-, other
than "this motor has grease fittings"?

thanks guys :-)

Probably weight 120-170 lbs, go run and get it. You can always alide
it on a 2x12 if you cannot lift it. Twi guys should be able to lift it
without problems.

Those heavy things (170 lbs), if I need to lift alone by hand, I do in
two stages.

Stage 1, lift it off the ground and put on a plastic bucket standing
upside down

Stage 2, lift it off the bucket and put on your tailgate.

Now, of course, I have a crane in my pickup and such puny things are a
non-issue to load.

By the way, I find it weird that a 7.5 HP 1730 RPM motor was made in
254 frame.

As for your bearing question, look closer at the name plate. It says
Front Bearing 307, shaft end bearing 309(?)

According to the tag, it was made in Over There by a company from
Chicago, Illinoisy. It's good for 60Hz, though.

It'll likely weigh only "about as much as a small horse." You'll
soitenly need a hoist for it.

Good question. Look up "307" and "309" bushings. (Hornady?!?)

Baldors with 254U frames use 6307/6309 ball bearings. shrug

hey mark

did you forget to add

"Mr Ernest Brook Started producing motors in Huddersfield, Yorkshire in
1904 and made this particular motor within the first year after that."

I sit corrected. (too lazy to stand)

I believe that Uncle Ben had sold that particular kite company shortly
after the 1752 demonstration, long before 1904, sir. ;) A printer by
trade, he was still busy printing anti-Queen stuff and the Poor
Richard's Almanack between those dates, though.
