Ridgid Table Saw Motor Upgrade-unbelievable!

I really like my Ridgid tabel saw. I have the accuracy to within .002” but it is severely underpowered :-(
I have the knowledge and resources to help the underpower problem :-)
These saws come with a 1.5hp motor. I got a 3hp, 230vac motor and the power improvement is 5 times what it used to be! I ripped through an 8/4 red oak scrap without issue and hesitation. I was afraid that with this power, burning would be an issue but its quite the opposite. With the power, the blade doesnt slow down so burning doesnt happen. THe power is unbelievable. It doesnt hesitate or bogg down. The cut is way smoother and there are NO splinters or tearout. I ripped this 8/4 oak with a 90 tooth blade. This is capable of smoking up the shop, but no! Went through it like nothing. Slick as snot!
This upgrade isnt something you can do just on whim. I spec’d this motor out for weeks. I had to find what type of motor was the original base, which is a 145t. 3400 rpm. I also had to go to a starter from the original switch. None of this is a big deal if you know how to do this. If you dont, dont try this at home kids, you could get hurt or burn up your new motor or worse, your shop. If i had to pay for this full out, its about a $500 upgrade. With my resources, I’m out about $45! Heck for $600 more i would sell the saw and go for the PM2000. I am rambling now, but only because I am so satisfied with this project! I have a whole new saw!
Once again, this is the result of giving a redneck too much time, money, and resources!
Todd!

When you say “Starter” I’m assuming you are referring to a motor starter?

I envy people that can do this kind of stuff for themselves. My electrical engineering abilities begin and end with drawing stick figures. Yup, I’m THAT bad that I have to compare it to a completely irrelevant field.

I’ve got one of the old school Ridgid table saws. It has 2.5 HP. I’ve never had a problem with its power. OK. So maybe I’m gloating. Sorry. P.S. I’m a redneck too so I fully understand where you’re coming from.

very cool!

curious though – are you using the original belt and pulleys? isn’t there a risk of the higher torque motor ripping the belt apart? usually the 3HP TS use a much shorter and more rigid belt – from what I’ve seen, most use a 3 belt system to accommodate the higher HP motor.

Makes me think of Tim “The Tool Man” Taylor. Ooh! Ooh! More Power! Aaaah!

Of course, Tim would wind up in the emergency room somehow.

For all of us who have the same saw but not the knowledge, please share the details. I would love to do this!

I hope you put better bearings in the arbor!! The extra torque with that motor will shred the factory cheap tiawanese bearings. When then do go they will fry the arbor. Its an expensive fix and I hope you arent stnading in front of the saw when it happens

Interesting….I have to admit that I too had the Tim “The Toolman” Tayler moment here. I am just curious as to what you did to the motor mounts and arbor assembly to beef it up for the extra RPM’s? $45 bucks…wow…

Last of all…being a safety fanatic….are you going to use a splitter or rive knife on that saw now….that 3hp motor can really kick back like the proverbial mule….I was curious as the pics show the saw without spitter or blade guard?
