| Abstract: | This paper puts forward the method of LMS adaptive noise counteraction to detect commutating signals of BLDCM which uses the voltage to detect the communtating position signals thus the moter work effectively in low rotate speed.Then finishing computer simulation and the scheme by using DSP.The results demonstrate that the adaptive noise counteraction method can be used effectively in BEMF detecting.The method provides more simplicity and validity than traditional method. |
