Abstract

The invention relates to a rotor rotation angle deviation adjusting method, a gate control method and an electronic device.The rotor rotation angle deviation adjusting method comprises the steps that when a Hall sensor is in a rotating state, a Hall rotating state signal is received, the reference electrical angle of a rotor is determined according to the Hall rotating state signal, and the actual electrical angle of the rotor is determined; according to the reference electrical angle and the actual electrical angle, a deviation electrical angle of the rotor is determined, the number of pulse width modulation interruptions corresponding to a first preset electrical angle is determined, and the first preset electrical angle is a correction parameter corresponding to the deviation electrical angle; according to the pulse width modulation interruption times corresponding to the first preset electrical angle and the deviation electrical angle, a correction electrical angle is determined, the correction angle is the electrical angle needing to be corrected in one-time pulse width modulation interruption, and the actual electrical angle is adjusted according to the correction electrical angle. And more stable operation of the motor is realized.

Description

technical field [0001] The present application relates to the technical field of motor control, in particular to a rotor rotation angle deviation adjustment method, a gate control method and an electronic device. Background technique [0002] At present, the gate control system includes: power supply, driver, servo motor and three Hall sensors. The hall sensor can detect the high and low levels corresponding to the change output of the rotating magnetic field of the servo motor, and the servo motor is provided with a rotor. Usually, the difference between the reference electrical angle and the actual angle of the rotor when the Hall transition signal is generated is compared, and based on the electrical angle of the rotor when the Hall transition signal is generated, the actual angle is corrected to be the same as the actual angle when the Hall transition signal is generated. The correction angle is the same as the electrical angle of the rotor when the Hall transition si...
