The problem with putting a sensor on the outside of a traction motor is that it is already too hot by the time it is picked up by the sensor. The things that burn out internally are probably already gone by the time the heat goes out the case. It is probably better to keep air flow through the motor(via a fan if necessary), and watch the current to establish a "norm" for your system rather than rely on a temperature reading.
