| Abstract: | As one of the three components of a brushless DC motor(BLDCM),Hall position sensors were used to detect rotor position which provided commutation signals for electrical switches,so its performance directly affects the motor's running.This paper investigated the influence on BLDCM due to failure and postion error of Hall sensors,and established simulation model of the BLDCM with Matlab to carry out the simulation.At last,the phase currents and torque waveforms of the motor in the two states above were given. |
