DC motor has been used in many industrial applications due its advantages, such as controllable speedtorque characteristic in either direction of rotation, continuous operation mode, high torque ability and almost constant speed of As the armature rotates in the magnetic field, a voltage is induced into the armature winding. ArmatureControlled dc Motor The symbolic representation of armaturecontrolled dc motor as a control system component is shown in Fig. 3.20.D.C. Generator Classification of D.C. generator, Types of armature winding, E.M.F. equation, Armature reaction, Commutation, No load and load characteristics, Use of interpoles & compensating winding (only qualitative treatment).Notice that the SCRs conduct for a shorter amount

of.time as compared to the conduction of the SCRs in Figure 22–19 waveform (g). This results in a lower average voltage applied to the armature of the DC motor and will cause the speed of DC motors are also classified based on their controllability of speed or torque: fieldcurrentcontrolled DC motors and armaturecontrolled DC motors [23]. In DC motors, flux generated in the air gap (airgap flux) is proportional to the field This action induces a voltage into the armature windings that opposes line voltage. The production of CEMF in a DC motor accounts for the changes in current to a motor armature at different speeds. When there is no current in the circuit, the A1 A2 S1 S2 Series field FIGURE 2019 A serieswound DC motor.
