A separately excited dc motor has an armature resistance Ra=0.05 Ω. The field excitation is kept constant. At an armature voltage of 100 V, the motor produces a torque of 500 Nm at zero speed. Neglecting all mechanical losses, the no-load speed of the motor (in radian/s) for an armature voltage of 150 V is ________ (up to 2 decimal places).
Correct : 600
