The motor should have the wires it needs for normal operation, since the motor manufacturer knows what the motor requires. They generally do go on the light side because wire is expensive, so hot-rodders often increase the wire. But for normal use it should be adequate.
The controller vendor needs to put wire on that will handle the max current the controller can put out. Again they tend to use lighter gauge wire, but it is not necessarily matching the motor.
If the motor wire is getting hot this indicates the motor is being operated at currents higher than was intended, or perhaps that it has a problem like a shorted turn.
Interesting that the old 600W controller is operating sensorless.
