The FP motors are really pretty strong motors but like any of the motors we use there are some flaws. FP's need to be run at the RPM they were designed for. Low RPM on these motors spells disaster as the fan that pulls colling air through the frame is very inefficient. At low speeds the heat from the motor will melt the fan (which is just pressed on the armature shaft) and it will stop working altogether. Remember that this motor is designed to power a drive around kids car in almost continuous duty until the batery dies, without failure. Keep the RPM up, and the motor ends unobstructed to allow cooling air to flow through and you should have no problems. Stall current is above 90 amps, so more than 100 watts can be dissipated in that little package.
