237 degrees (that's fahrenheit I hope
) is (too) hot for a motor. Always try to keep the temperature underneath 200/210. The bent rings and rust give me an indication that the motor was already malfunctioning before it overheated, and the the motor getting this hot is not the reason for the problems but a result.
Best thing you can do is to buy a new motor, since this one just isn't good anymore. If you ever want to use the rotor or some others parts of this motor, you should measure and check if everything is still straight en good. There is a good chance that the rotor for example is bent too, and using it in another motor might just cause damage to the new motor too.
So if it fits your budget throw it away and buy a new one. My advice with motors is to always buy a new motor, and when you buy one second hand, always get it apart and check if everything is still ok, and even than there still might be problems that are hard to check, like the magnetic power of a rotor.
When you want to buy a new motor, check for either a X11 (they are not that expensive anymore even new) or otherwise the new X12. Or check your local club to check what they are using (both speedo and motor), and try to do the same. That way you can help each other out.
