Abstract

This paper decribes multi-phase BLDC motor with a minimum torque pulsation among BLDC motor used for electric propulsion system. Multi-phase BLDC motor has characteristic that phase of stator has more than 3-phase. This paper is modeling two type of BLDC motor, one has 3-phase and the other has 7- phase , and it shows simulation of them comparing its characteristics. As a result of simulation, the 7-phase BLDC motor shows better performance in terms of torque pulsation. It is also found that the torque pulsation is reduced further by increasing the number of phase.
