Hall sensor magnetic field position information detection method based on three-phase equilibrium condition

The invention provides a Hall sensor magnetic field position information detection method based on a three-phase equilibrium condition. The Hall sensor magnetic field position information detection method comprises the steps that 1, an experimental instrument is assembled, and the position relation of two sets of Hall sensors is determined; step 2, the X-axis Hall sensing unit group (5) comprises two Hall sensors, the phase difference of the two Hall sensors is 120 degrees, and X-axis three-phase signals are generated by using a three-phase equilibrium condition; 3, based on the X-axis three-phase signal generated in the step 2, converting the X-axis three-phase signal into an X-axis two-phase signal by using a three-phase to two-phase sensor; step 4, on the basis of the X-axis two-phase signal in the step 3, using an arc tangent function to realize position information of an X-axis magnetic field; and 5, repeating the steps 2-4 in the Y-axis Hall sensing unit group (4) to obtain the position information of t
