. . . . In this paper, a novel sensorless drive for brushless DC (BLDC) motor using the fuzzy back-EMF observer is proposed to improve the performance of conventional sensorless drive methods. Existing sensorless drive methods of the BLDC motor have low performance at transients or low speed ...
Due to the switching noise of the field effect transistor (MOSFET) when the drive signal of the brushless DC motor is switched between high level and low level, its waveform often has large fluctuations which can cause inaccurate sampling of back-EMF and the motor fails to work optimally. The...
