Pool pump duty motor

[SteveM]

Someone locally is selling a "pool pump duty" motor.

Would this be suitable for running a machine like a mill or lathe?

Probably not, mainly for mechanical reasons.

What would be "mechanical" reasons?

The motor is a standard mount (looks like a 56 face mount)

Pool pump would imply continuous duty and a constant load near max. Worth a try, depending on the price.

I am using a similar motor for a home-made grinding station; admittedly intermittent duty and light loads.

you would also need to be careful of the output RPM of the motor....

3450/1725 two speed.

That's one of the reasons I'm interested.

There you go...just what the doctor ordered.

May be a problem with the milk since it appears to be a horizontal mount motor, which is ok if you have a horiz lathe or mill, but may be a problem with a vertical lathe or mill

I do not see any problem, other than the turning direction, can't be reversed. The flange looks like it can come out.

I was given what they called a 5hp version of one, it was rated like a compressor motor. It had a tapered output shaft, check this one. I built it up and turned it down to fit a pressure washer pump. It wouldn't start the pump against the unloader valve. Used it for a couple of years till the magic smoke leaked out. Replaced it with a cheap Chinese 3 hp one. It now starts against the unloader valve.
Note at low speed the one listed is only 0.1 Hp meant to circulate the hot tub.

Ah, that's going to be a problem.

Was looking at it for a lathe and/or small horizontal mill, but 0.1hp isn''t going to do it.

Thanks for spotting that and thanks everyone for your comments.

A lot of those pump motors have oddball shafts that are designed to directly mate with an impeller. You may not be able to mount a sheave on the motor with doing some rework.

Note that the label on the motor specifies:
"Mount horizontal with vents down."
'Could be a limiting factor too.
