Abstract

DC motor is a motor that converts electrical energy (input DC current/voltage) into mechanical energy (output torque). This paper presents the transient analysis of a separately excited DC motor which is fed from a variable DC source. It focuses on the simulation of the DC motor model using the MATLAB/SIMULINK application to realize and analyse its transient responses under controlled conditions. The simulated model was used to calculate the speed (N), torque (T), armature current (Ia) for the motor at transient no-load condition. Variation of selected DC parameters results to a consequent change in the output characteristics of the model. These parameters include the field current, armature voltage and armature circuit resistance.
