Abstract –
Permanent Magnet Brushless DC (PMBLDC) machines are more popular due to its simple structure and low cost. Improvements in permanent magnetic materials and power electronic devices have resulted in reliable, cost effective PMBLDC drives, for many applications. PMBL motors find applications in diverse fields such as domestic appliances and automobiles due to its low cost and performance. Modelling, simulation and experimentation of drives with new converter configuration and control schemes are essential for making this drive competitive. In this paper, a comparative study between sensor and sensor less control of four-switch Inverter fed PMBLDC is discussed and Simulation model using transfer function of BLDC motor is presented. Hardware implementation is done with DSP processor TMS 320LF2407.
