Thermal overload protection is active only when using the motor with a Novak controller designed with the TOP sensor activated---Havoc 1S, 2S, 3S, etc. We removed the TOP from our GTBs (for example) years ago, because racers did not want their systems to stop because the motor was overheating.
Our racing escs have not included this circuitry for years. The blue sensor wire
senses the motor temp, but the circuitry must be built-into both components for it to work.
Dynamic timing escs have created a horrible issue with burning up stators; this was an important reason why we designed the Ballistics to be completely rebuildable; racers can replace their stators and weakened magnets without returning the motors for service.
We added this Motor Warning(PDF / sixth on list) to our web site front page a couple of years ago:
Technical Updates
Our upcoming Havoc Pro SC, with 8 levels of built-in timing, features circuitry that will turn off the timing when the
controller starts to overheat; this allows the racer to complete the race with no timing, but protects the esc from damage.
