Vacuum problem

One of my vacuum timers did not have power so I checked it out and something had blown the breaker.  I checked the vacuum motors and one smelled like melting plastic and the other smelled fine.  So I replaced the stinky motor and everything worked great!

Motor Starter Meltdown

My motor starter looks like one of the legs fried? One wire melted (first picture) and the terminal in the contactor melted (second and third picture) and it also blew my three phase breaker. My question is: What do you think the problem is? Is it just the motor starter? Pump motor? Who knows what the problem is? I guess I will know after I check the voltages and replace the contactor like Greg suggested.
