A 220 V shunt DC motor rotates with speed of 1800 rev/min at no load condition when the current is 8 A. It has a field resistance of 6 , an armature resistance of 3 2 and a brush drop of 3 V. Assume the flux does not vary with load. (a) Find the speed of the motor in rev/min when the motor current is 46 A. (b) From the result in (a), find the mechanical torque and power generated by the motor.
