This work mainly focuses on Matlab Simulink model for electronic commutation of BLDC motor and co simulation of the model by using Xilinx System generator tool. The BLDC motors (AKM21E) are available in small size with good speed/torque characteristics. Since, the efficiency and dynamic response is high compared to brushed DC motor, they have widely used in various applications. We are using BLDC motor for adjusting the focus in radio telescope. The efficient electronic commutation is designed and tested by using modelling in Matlab Simulink. The Co verification of the model is done by using Xilinx system generator.
