Abstract :
This paper suggests the drive mode of Brushless DC (BLDC) applying the operation mechanism of Permanent Magnetic Synchronous Motor (PMSM). The BLDC operation method which operates like PMSM in the existing paper uses a complex formula. In this paper, however, the time of controller operation and count of controller execution are multiplied to the current speed to execute theta estimation. Also, the compensation for the occurrence of acceleration and deceleration is proposed. The proposed estimation theta method was confirmed through simulation and verified through experiment.
