A 230 V, 250 rpm, 100 A separately excited DC motor has an armature resistance of 0.5 Ω. The motor is connected to 230 V DC-supply and rated DC voltage applied to the field winding. It is driving a load whose torque – speed characteristic is given by TL = 500 – 10ω, where ω is the rotational speed expressed in rad/sec and TL is the load torque in Nm. The steady state speed at which the motor will drive the load is ________ (in rpm)
