Dual-motor synchronization method and system based on Hall sensor

The invention relates to a dual-motor synchronization method and system based on Hall sensors, and the method comprises the steps: S1, recording the time difference between two adjacent times of passing of each motor through a corresponding Hall sensor in a dual-motor operation process in real time; s2, calculating a difference value of timestamps when the two motors pass through the corresponding Hall sensors, judging whether the difference value is greater than a set difference value threshold value or not, and if so, entering S3; otherwise, entering S5; s3, the rotating speed of one of the two motors is adjusted to be the reciprocal of the difference between the time difference of the other motor passing through the corresponding Hall sensor for two adjacent times and the time stamp difference value of the two motors; s4, returning to S1 after the two motors operate for one circle; and S5, adjusting the rotating speed of one of the two motors to be the reciprocal of the time difference of the time when the
