The built dynamic model of matlab programming DC motor was validated via simulations and experiments. The performance of matlab programming controller was also proven via experiment. Abstract: BLDC Brushless DC motors have found matlab wide range of functions in commercial automation, automobile, aerospace, instrumentation on account of their long working life, compact form, reliability and occasional maintenance, high efficiency and better speed torque features. This Paper is an exercise in opposition t developing matlab simulink model with matlab programming parameters of matlab real trapezoidal back emf type of BLDC motor. The model is then analyzed under aiding and opposing loads. The diversifications in motor speed torque characteristics, back emf and latest drawn by matlab programming motor for both no load and loaded aiding and opposing loads situations is analyzed.
