Sensorless control of the BLDC motors from near-zero to high speeds

  title={Sensorless control of the BLDC motors from near-zero to high speeds},
  author={Tae-Hyung Kim and Mehrdad Mark Ehsani},
  journal={IEEE Transactions on Power Electronics},
This work presents the theory and implementation of a novel sensorless control technique for the brushless DC (BLDC) motor. The proposed new sensorless drive method solves the problem of the sensorless BLDC motor drives at very low speeds. It provides a highly accurate and robust sensorless operation from near zero to high speeds. For this purpose, an approach, a new flux linkage function is defined, that is speed-independent. The validity of the proposed method is verified through both… CONTINUE READING
