| Abstract: | In comparison with the use of position sensors, the applicaion of sensorless Brushless DC Motor is more reliable and economiacal. At present, and the principle of zero-crossing detection of the back-EMF is one of the most successful technology used for detection of the rotor-position. This paper analyzes the rotor-position error caused by the zerocrossing detection and a compensation method is proposed. |
