This paper presents the simulation of sensorless operation of permanent magnet brushless direct current (BLDC) motor. The position sensorless BLDC drive simulated, in this paper, is based on detection of zero crossing from the terminal voltages differences. This method relies on a difference of line voltages measured at the terminals of the motor. It is shown, in the paper, that this difference of line voltages provides an amplified version of an appropriate back EMF at its zero crossings. The… Expand
