I am not an electrical engineer, but...
the controller is like a water valve that you can open and close or leave someplace in the middle. A 1/2 inch water valve can supply between 0 and 20 gallons of water per minute. a 3/4 inch water valve can supply between 0 and 40 gallons of water per minute.
Similarly, a controller can be small or big. A small one might provide between 0 and 100 amps, while a large one might provide between 0 and 200 amps (made up numbers).
A 'too powerful' motor cannot draw more power than the controller is designed to supply. If you have the same old small controller, a new 'more powerful' motor will only run as fast as the old one because it is only getting the juice that the old one got.
If your controller is getting hot, it is possible that it is dying or that the connections are indeed corroded or loose or something. All the juice from the batteries to the motor goes thru the controller.
