Permanent magnet Brushless DC (BLDC) motors are gaining popularity mainly because of their better characteristics and performance in comparison to other electrical motors. BLDC motors are generally controlled using a three phase power semiconductor bridge. For starting and providing proper commutation sequence to turn on the power devices in the inverter bridge, the rotor position sensors are required. Based on the rotor position, the power devices are commutated sequentially every 60 degrees. This paper presents MATLAB/SIMULINK based simulation of BLDC motor drives. BLDC motor drive operates in six modes for one complete revolution of the rotor. The complete analysis of six modes of operation with position of rotor has been presented in this paper. The switching of the IGBT switches and corresponding phase currents and line voltages are shown here for each sequence. The presented BLDC motor drive is based on hysteresis band PWM current controller for generating modulated switching signals.
