Three-Phase Inverter Fed BLDC Motor Drive

Brush less dc motors have only decades of history. They have been gaining attention from various industrial and household appliance manufacturers because of its high efficiency, high power density and low maintenance cost, silent operation, compact form, and reliability. This paper describes the procedure of deriving a easy model for the brush less dc motor with 120-degree inverter system and its validation in the MATLAB/Simulink platform. In order to evaluate the model, various cases of simulation studies are carried out. Test results thus obtained show that, the model performance is satisfactory.
