On 220 you allow the motor to draw its’ power through 2 lines and 2 breakers. That allows for a cooler running motor which improves its’ life and the breakers run cooler. It still uses the same amount of power but it can draw it through 2 lines which allows for a more efficient running motor. This comes into play upon startup and under a heavy load.

Some of my tools that came with a 110/220 option were run on 110 until I dropped a new line in for them. They would take longer on startup, which is hard on the motor, and they would dim all the lights in the shop. Everything is running good on 220 though.

Buying the bigger motor is a better way to go for sure.
