Abstract

Brushless DC Motor (BLDCM) usually has 3 hall position sensors, and they play a key role for motor control. In order to determine hall locations relative to the stator windings, the permanent magnet motor rotor flux-oriented method has been analyzed and it provides a theoretical basis for us. Thus, the exact locations of sensors can be found. Through the decode logic of 3 hall signals, 6 drive signals for the three-phase full-bridge can be got. In this paper, the experiments are achieved, and the motor ran stability. The current waveform is recorded and analyzed, and it shows the locations of hall sensors and the decode logic are correct.
