Abstract: The working efficiency and effect of commutation ripple of BLDCM are directly determined by the installation position of hall sensor. This paper presented three general methods of hall sensor positioning method: short pulse positioning method, magnetic potential calculation method and phase compensation method. Via PWM control methods to validate these methods, and the experimental data show that three methods can achieve normal commutation, low commutation ripple and low installation errors. The engineering and technical personnel can refer to three methods
