What kind of electric motor doesn't lose torque with increasing speed?
Doesn't a typical electric motor have an almost linear drop of torque with
increasing speed? Highest torque (stall torque) at (almost) 0 speed, 0
torque at the shaft at max. speed (when all the power is used to overcome
internal friction and other losses)?

The characteristics of a complete servo are of course also determined by
the controller, but the controller only can reduce the max. torque the
motor can deliver at any given speed, it can't increase it.
