Example Embodiment
[0036] Attached below Figure 1-Figure 7 And specific examples further illustrate the present invention.
[0037] The steps to realize the correction method of the Hall sensor installation position deviation are as follows:
[0038] (1). Such as figure 1 As shown, the control signal 11 is input into the MCU module 12, the power supply 16 provides power for the system, and the signal output by the MCU module realizes the control of the motor 14 through the inversion of the inverter unit; set the output duty of the PWM module in the MCU module 12 Ratio D=10%, execution time Ti=100ms;
[0039] (2). Set the relative installation electrical angle α of the three Hall sensors HA, HB, HC in the Hall sensor group 15, α=60° (or 120°), and determine the number of pole pairs of the controlled object motor N = 5;
[0040] (3). Fix the three Hall sensors HA, HB, HC according to the mechanical angle of α / N=60° / 5=12°, and then fix the three fixed Hall sensors on the circumference of the motor stato...
