I’m looking for a bigger motor for my old craftsman 10” cast iron fence table saw.
Looking for budget options, I stumbled on Pool or hot tub jet motors.
They run same rpm and shaft size is 5/8 as well.
When the HP shows 3 but the SF (service factor) reads 1.15, what does that really mean?

Is it a true 3hp that can put out 15% more power when overloaded?

Thanks guys? This is all new to me and I googled it but I need it spelled out like a kindergartner.

I’d need Clockwise orientation as well, right? Pully spins toward the saw.

Service factor - SF - is a measure of periodically overload capacity at which a motor can operate without beeing damaged

higher grade motors tend to have higher service factors

Service factor means the motor is rated run at continuous 15% overload ( 3 HP x1.15 = 3.45 HP ). Operating current would be "about" 15% over rated FLA but its not exact due to temperature and power factor effects.

The temperature rise may exceed the rated temperature rise while operating as above, but should not exceed the temperature rating of the insulation system. Operating at elevated temperature can shorten the insulation life ( common rule of thumb is a 10 deg C increase cuts the expected insulation life in half).

While you might be able to adapt a spa motor to your TS, you can buy CM table saws all day long for less than what people get for the motor after they remove it and junk the saw. Plug and play bolt pattern and all.

I ended up rolling the dice on a Vevor tefc 1.5 hp for $156
It’s quiet and I was able to rip an oak 2x6 easily. Should work out well, if it holds up.

Good choice for tefc; this should avoid the sawdust problem and having to periodically blow it out.

And unless you're running some production jobs, the duty cycle on a table saw is really quite low. With mine, most of the time at the saw is setting up for a cut, not actually doing the cutting.

Thanks and yeah, it’s going to just be used for random projects around the house. It’s a nice upgrade from the little contractor saw I’ve been using.
