Answer to Question #264396 in Engineering for naz

Question

A 500V, DC shunt motor has armature and field resistance of 2.5Ω and 500Ω respectively.

When the motor run unloaded, the line current is 3A and the speed is 1200rpm. Calculate

torque Developed at full load armature current of 50A, the motor speed if the load is

constant-torque type when 3Ω resistance is added to the armature circuit and the motor

speed if the field is reduced by 15%.
