Abstract(E) | The main issue is deterioration of motor N/V performance caused by supply current distortion in sensorless brushless DC motor start. Therefore the main purpose in this study is to reduce supply current distortion and to achieve reduction, estimation of rotor initial position is examined without adding additional hardware such as sensors. The conclusion is that estimation of rotor initial position within four quadrant range is succeeded by changing software only and supply current distortion and convergent time are reduced by changing direction of single phase excitation according to initial position. |
