[ 1 ] - Sensorless Commutation of BLDC Motor without Low Pass Filter and Phase Shifter
In this paper, a novel sensorless commutation method for BLDC motors is presented to simultaneously eliminate phase shifter and low-pass filter. An analytical model of the motor is presented and ripples resulted from the current commutation are investigated in detail. By detecting the zero crossing points of the unfiltered voltages of the motor terminals referred to the ground and DC link, the...
