The armature controlled DC motor discussed in this chapter has an inherent “back emf” feedback loop present. Another control configuration is called field control. In this configuration the “back emf” feedback is absent. The circuit diagram for a field controlled DC motor is shown below.
The input to the motor is the field voltage, and the output is the electromagnetic torque,
The impedances are based on current (FV) and voltage (PV) on the electrical side and torque (FV) and angle (PV) on the mechanical side. K is the current-torque constant.
a. Construct the impedance diagram for the field controlled DC motor and label all signals.
b. Attach a load consisting of an inertia, J, plus friction, B, to the mechanical side and compute the transfer function,
