Here’s a metaphor for you.


Imagine a 5 gal bucket. You fill it with the garden hose and it takes 1 min. Now image that you take your hose and a hose from the neighbor’s house and use them both to fill the bucket. Of course, it takes half the time.


The windings of your motor are just like that bucket. They have to fill up with electricity to turn the motor. 220v allows them to fill faster, thus improving performance. In almost every situation it will help.


Also, most table saws draw enough current that using a 100ft cord is not recommended. Unless that cord is 10 gauge or bigger.
