No load just means that there is nothing attached to the rotor creating drag on the rotation of the shaft. The losses at no load are so miniscule that they really do not matter. The losses that really matter are shown in the comparison between the CC motor and the HK motor of the same size and spec. Those huge differences are what create the heat on a cheaper motor, where the CC motor will remain reasonable temp wise.
