A shunt-connected DC motor operates at its rated terminal voltage. Its no-load speed is 200 radian/second. At its rated torque of 500 Nm, its speed is 180 radian/second. The motor is used to directly drive a load whose load torque TL depends on its rotational speed ωr (in radian/second), such that TL = 2.78 x ωr. Neglecting rotational losses, the steady-state speed (in radian/second) of the motor, when it drives this load, is ________.
Correct : 180
