is this good enough for 5 lbs plate weight?

for diy tt
is this have enough energy?

I’m sure it’ll get 5# spinning but guessing it’s not going to get up to speed quickly. What was it used with previously?
These days, I like turntables with torque. That motor may not be the one.

the person dont talk to much,,maybe he got from the junk yard
what is 5#?

5# means 5 pounds. If you use that to belt drive a platter it should be more than strong enough. I would take the motor apart and clean the bearings well and relube them. After that, plug it in and try and stop the shaft, that will give you an idea of it's torque.
If you are serious about getting a TT I would be looking for a used TT that just needs a good cleaning and lubrication and probably a stylus.

2-pole dual voltage motor. Multi-pole motors are generally preferred for turntables above basic level build.

Once you get the platter spinning it takes very little power to maintain that. Only time motor torque really factors in is with startup speed.

I only agree with your first sentence above - but I think torque also matters for “PRaT” - which I know is a concept some don’t recognize.

Just keeping a platter spinning at about 33-1/3 with no load isn’t the same as keeping it spinning with a load - even if the playing load is seemingly light. I used to think “PRaT” was nonsense; now I don’t.

Aren’t two-pole motors contraindicated for use with magnetic cartridges?

Pretty much, location, location, location.

in an external pod mounted well away from the pickup its fine. Underneath directly below the arm it will cause you issues.

Looks exactly like the motor from a furnace condensation pump. I've been playing with one recently for a different project. Not very much torque for the power it uses. Bearings are probably not up to the task for TT usage, either. It might work, though. As others have said, it might take a while to get the platter up to speed.
