Brushless DC (BLDC) Technology and its Application in Articulation of Weapon System Launching Platform using Electromechanical Servo Drive is presented. The angular position or linear position of a system can be controlled by rotation or articulation in elevation and azimuth plane. In linear position control angular rotation of the BLDC motor is converted into linear motion by using Electromechanical Actuator to articulate in desired direction. For articulation of a weapon system launching platform, Electromechanical Servo Drives are used. Due to inherent properties of BLDC Technology BLDC Motors and Drives are profoundly used in military and strategic weapon system applications.
