Abstract :
Brushless motors, which finds diverse applications in industries and automation systems, combine high reliability with high efficiency at a lower cost in comparison with the conventional brushed motors. The reliability and efficiency can be further improved by incorporating a multiphase design which however increases the system cost and the inverter circuit complexity. This paper proposes a five phase brushless dc motor drive and describes how a AT89C51 microcontroller can be used to drive it. The design and the MATLAB/SIMULINK model of the proposed five phase BLDC motor and its driving circuit is discussed and the results are presented.
