This paper exhibits a simplified way of controlling of the Permanent Magnet Brushless DC Motor (BLDC) using PI Controller with the comparative study & detailed performance analysis for different load applications in MATLAB environment using Sim Power System (SPS) toolboxes and Simulink in Discrete timespan. A various industrial application such as conveyors, pump load, elevators, lift, etc., in different operating condition like staring mode dynamics, braking mode dynamics, the step change in speed command, etc., have been tested. The choice of BLDC Motor has many advantages over brushed DC motors and induction motors which is of higher speed ranges, long life span, good speed versus torque characteristics, high dynamic response, long operating life, high efficiency, and noiseless operation.
