Exercise 2: Self Excited DC Shunt Motor^11
Aim: To Simulate the dynamic modal of a Self Excited DC Shunt Motor and plot various Characteristics curves and analyzes the results Software Requirement: MATLAB Circuit details and input parameters Ra = 0.6 ; Armature resistance in ohms La = 0.012; Armature Inductance in Henry Lf = 120; Field Inductance in Henry Rf = 240; Field Resistance in ohms J = 1; Moment of Inertia B = 0; Friction Coefficient Laf = 1.8; Mutual Inductance between field and armature Va = 240; Supply voltage W ; Speed of the DC Motor P = 2.5; Power
Procedure:
- (^) Step1-Initialize the input parameters and write coding for the as per
requirement of plots in m file and save it
- (^) Step 2-open new Simulink and make mathematical modelling as per
circuit diagram and save it
- (^) Step3-Run the m file first ,Armature inductance after that run Simulink file
- (^) Step4-View the result in Scope
- (^) Step5- Again run m file and view the plots
- (^) Step6-Make various plots and write the Results
Open M file and save it
Run the M file (input parameters file)
Run the Simulink file & view the results scope
