Cicily Antony T, Beena M Varghese, Anish Gopinath

The permanent magnet brushless DC motor found more popularity in industrial, residential and aerospace applications because of their inherent advantages over conventional brushed DC motor. To impact rotation to this motor electronics are nece=ssary. The paper mainly concentrated on multiphase machines and developed the ten step commutation logic for five phase BLDC motor. The four quadrant operation and fault tolerant capability of five phase BLDC was evaluated with ten step commutation logic and the results are presented. The simulation of presented commutation logic was carried out in MATLAB/SIMULINK and the results are validated with the experimental results. The hardware implementation of ten step commutation was done in an AT89C51 microcontroller platform and the results are presented.
