Question: A 2 4 0 V , 2 hp , 1 2 0 0 rpm de shunt motor drives a load whose torque varies directly as

A 240 V,2 hp,1200 rpm de shunt motor drives a load whose torque varies directly as the speed. The armature resistance of the motor is 0.75 ohms. With If =1 A, the motor draws a line current of 7 A and rotates at 1200 rpm. Assume magnetic linearity and neglect armature reaction effect.
