What is the current rating of the motor, and what is it set at? What's the voltage rating? How fast are you trying to cut?
When you say very, very hot. Can you hold it? Heat is usually from either too much voltage, or too high of current.
A bigger motor may not help, because larger motors usually have a lower top speed.
A higher lead ballscrew may be a better answer.
