abstract
Various reduced parts convertors were proposed for the two-phase brushless DC (BLDC) motor and a generalized design methodology was established for the multi-phase motor. As the examples of multi-phase BLDC motors, the four-phase and five-phase were considered in the study. It was found that a four-phase BLDC motor could be operated as two of a two-phase BLDC motor with modification of winding connection. This meant that only four switches were enough to drive a four-phase BLDC motor.
