To control the speed of DC shunt motor using field control method. As we are neglecting the change in the flux , we can say that torque is proportional to armature current. Reverse the motor terminal. SPEED CONTROL OF DC SHUNT MOTOR Date : AIM: To study the speed control of the given dc shunt motor by field control method and armature control method. Depending on the connections of the field to the power supply, the speed and torque characteristics of a brushed motor can be altered to provide steady speed or speed inversely proportional to the mechanical load. Though at heavy loads, decreases in a small amount due to increased armature reaction. Characteristics of DC shunt motors Torque vs. armature current (Ta-Ia) In case of DC shunt motors, we can assume the field flux to be constant. External characteristics of shunt ... brush and produces electromagnetic torque to rotate the rotor at a speed!. Plugging speed torque curves DC separately excited motor .
