I have been realatively happy with the TS3650 from the durability/accuracy/engineering standpoints but the saw is underpowered for a number of necessary cuts in woodworking. So, I decided to undertake the upgrade of the power system after seeing an article here about a cheap way to do so. Here are my product choices and the final result….

Sorry for the posting delay fellas… Got on my honeydo list!

Now the Motor is a 3hp I bought on ebay in a 56 frame style. It IS an open frame type so dust collection is a real concern to keep from cloging the brushes on the motor but this is highly doable. The starter (shown in these pictures in test wiring mode) is a WEG purchased from the same online vendor. I got the pair for under $300 and the installation and wiring was pretty much a breeze. (don’t forget to pray!)....

I did add a new belt. The stock belt on the 3650 is supposedly 41.7 inches. Mine must have streched because it got to the point that it would slip badly with the blade down under 1 inch. This was unnaceptabel so i found a belt supplier online who sold me a 40 inch (I bought 2 thinking I needed a spare then was worried that they may not fit, but did perfectly) and this belt does the job from 0 to full height. The belts were around $10 each.

Results: In a word… WOW! The difference is amazing. I’m ripping 1 inch red oak and the saw isn’t reacting at all. I even went to a full kurf blade and the motor just plows right through. If you do more than light work with your TS3650 and you really don’t want to spend a bundle on a new saw this is most decidedly the way to go…..

Post Note: I did some dado work with my new Infinity Dadanator (wonderful!) cutting 23/32” by 1/2” deep dados in red oak. The results were spectacular and the saw didn’t flinch or bog in the least. This motor is most decidedly a huge upgrade.

If you want specifics on vendors just drop me a note and I’ll be happy to provide.

I have the TS3650 and would be interested in reading more.

Nice upgrade, kinda like putting a V-8 in a gremlin!!!!

Right now I only have 110V set up in the basement but

the fit looks really easy. Something for me to think about!!!!

So is the three horse moter 110V or 220V?
If I’m correct, then you doubled the horsepower of your saw?
And yes, I would like to know what vendor you got everything from.
Also, when you say “starter”, what is that? Are you referring to the on and off switch? Or does this motor require something extra? I ask because the few 3HP motors I have had any dealings with only rquired a switch. What i called the “starter” (don’t know a lot of the terms) was the capacitor (again, not sure if I’m using the correct terminology) that it appears this motor has two of in the last photo.
If we are talking about a switch, the original TS3650 setup with the one and a hald horse motor is designs to be run on 110V or 220V simply by rewiring the motor. So will the original switch from the saw not work?

I think this is an induction motor so there are no brushes to wear out.
The main concern would be sawdust keeping the starter contacts from touching, thereby preventing you from starting.

Thanks Sarit… Electrical motor newbie here for sure! As for the starter William, it was a recomendation and I really don’t know for certain if it’s necessary for not. If not you can save $90 and do this for the cost of the motor ($189 on ebay)..... 3 of which are available in the current listing.

The link below is the vendor site and the next link is the motor I ordered.

Thank you. My current financial situation completely forbids even considering this upgrade. However, I am writing all this down in my idea book.

I just came across your posting here, and I was wondering how the saw is performing after this long. I was curious if there were any issues with the arbour or bearings using a bigger motor than the saw was designed for. I would love to upgrade mine too.
