Delta buying motors from Sears

I just picked up a late model Delta Unisaw at a local auction. The motor is rated 3 HP and the cord has a molded 15 amp, 110V plug. Since I had to buy some heaters for a 2 HP Baldor motor last week and they were rated for 18.5 amps at 110V, I wonder how Delta gets 3 HP from 15 amps or less. My only explaination is that they buy there motors from Sears. Sears and now Ridgid are the only manufacturers that I knew could make 550 watts equal a full horsepower. I guess they can make their motors operate at 130% efficiency. Leigh@MarMachine

most unisaws are 220, that should be a 15a 240v plug

Somewhere there is a matching 120 volt 15A outlet wired to 240 volts :-)

As for Sears, the catalog that yesterday's mail brought shows some new Craftsman "light industrial" table saws, they don't even bother stating a horsepower rating in the description. That's a new twist.

Haven't you heard? That is a major invention that came from the Sears Marketing Research Labs. It was first applied to air compressors. They are getting 5 HP from an ordinary 115V wall socket. That must be 300% efficiency. This is truly astounding. Who needs cold fusion?

Now Sears is applying this new technology to table saws. Today they are only able to get 130% efficiency. With their top marketing researchers on the project, they should be able to push it up to 300%. From there only the sky is the limit! ;-)

^^^^^^^^^^^^^^^^ This is known as "virtual power." But, tell me, is the ever-present risk of kick-back on table saws consistent with the actual power or the virtual power? Seems their advertising people may have another gimick they haven't used.

They have much smaller horses than the rest of industry. Shetland ponies, I think. 10,000 foot-pounds per minute instead of the normal 33,000. Kept on a secret Sears horse farm somewhere.

That would explain why my new Kenmore fridge makes ice, even though I forgot to plug it in.

I'll bet you're right. My 3HP single phase Uni-saw has a

230V only (not restrappable for 120V) motor made for Rockwell by Baldor.
