  • Publication number: 20250125754
    Abstract: An intelligent control system for a circular high-power vibration motor is provided. The control system controls a plurality of operating parameters of a plurality of vibration motors by a control module so as to cooperate in a process of generating vibration. The plurality of vibration motors are mounted on a motor frame and distributed evenly at equal angles. Eccentric members are respectively provided at two ends of a central shaft of each vibration motor. A detection module detects rotation phases of the eccentric members, and the control module is configured to adjust one or more vibration motors to accelerate or decelerate rotation based on phases of the eccentric members, so that vibration parameters generated by the plurality of vibration motors are the same or tend to be the same. The detection module includes a plurality of photoelectric sensors.
