英文摘要The utility model relates to a brushless DC motor speed measurement device based on a hall element, which comprises a hall signal processing unit, a singlechip processing unit and an external interface unit, wherein the hall signal processing unit receives a hall signal input by the hall element of a brushless DC motor, and the hall signal is output to the singlechip processing unit after filtering and shaping the singlechip processing unit carries out core algorithm processing of the signal input by the hall signal processing unit, and then outputs speed information through the external interface unit and the external interface unit is provided with 5V and 3.3V logic level external output serial interfaces. The utility model utilizes the speed measuring function of the hall element, designs a special speed measuring module, transfers information through a serial port, and thereby facilitating the system integration, better solving the problem of speed measurement fluctuation, and having a failure report mechanism and better generality.
