Is it tripping the breaker instantly or after a short period of time (and which one… house circuit breaker or the one on the saw)? That machine has a universal screamer motor (no capacitor btw) with a plastic housing. The brushes could be the culprit, which are easy to check, but usually won’t cause the breaker to trip. If it’s tripping instantly, then you have a short somewhere that needs to be tracked down. If it’s tripping after a short period of time, I’d check for binding somewhere.

Unfortunately, if you did heat the machine up by pushing it too far, it is entirely possible that you have warped the plastic housing on the motor – which houses the rear bearing. If that is the case, you might as well toss the machine, as a replacement motor is more expensive than the saw itself. Here is an example of what a trashed rear bearing housing looks like on one of those motors:
