How big a motor for a tablesaw ?

I have a big old cast-iron Wadkin 10" cabinet saw. It's more like a
PM66 than a Unisaw, but a fair chunk of iron whatever.

Sadly though, it was built as 3 phase and converted to single phase by
swapping the motor. And the motor that went on is a pathetic little
thing.

So, if I swap for a new and suitably sized (still single phase) motor,
what size should I go for ? What's a reasonable rating for a saw of
this ilk ? The mounts are pretty standard, so I should have a fairly
free hand in what I go for.

1.5HP used to be the standard for 10" saws, 3HP is better. Anything in there
should be all right.

Basic PM 66 and Unisaw (and General 350 and most others) have 3 HP motors. For
heavy duty use, there's a 5 HP option. Either should be fine.

1 phase or 3 phase?
5 hp is about the largest 240 volt 1 phase

I have 3HP single phase on my 10" cabinet saw.
Has never talked back to me once :) Has handled everything I have thrown at
it so far.

my powermatic has 3 HP. I haven't felt a need for more. 10" cabinet
saws come with IIRC up to 5HP motors on them
