Problems solved by technology

[0003] In the existing technology, the control method for multi-motor clusters is relatively simple, and the multi-motor system is controlled by relying on the load self-balancing method, that is, the intervention of the source of motor control is less, and the common belt conveyor equipment relies on the soft connection of the belt Autonomous power balance and speed difference coordination of multiple motors
In recent years, with the emergence of hydraulic couplings and magnetic couplings, the control level of multi-motor fleets has been improved, but the intervention is still through the transmission, and the source of the non-driving force—the motor end.

Abstract

The invention discloses a multi-motor cluster system driving control device, method and system. The multi-motor cluster system driving control device comprises a multi-motor comprehensive control unit, a plurality of motor control units and variable frequency drivers corresponding to the motor control units, wherein in the plurality of motor control units, one motor control unit is set as a main motor control unit, and the rest motor control units are set as slave motor control units; wherein the multi-motor comprehensive control unit is connected with the plurality of motor control units in series through two groups of optical fibers, the plurality of motor control units are connected with the variable-frequency driver, and the variable-frequency driver outputs signals to the motors. Themulti-motor group system is managed in a unified mode through the multi-motor comprehensive control unit, and the automatic control level of the multi-motor group system is improved.

Description

technical field [0001] The present application relates to the technical field of drive control, in particular to a drive control device, method and system for a multi-motor cluster system. Background technique [0002] Multi-motor cluster variable frequency drive devices are widely used in industrial occasions, such as steel long rolling production lines, coal mine belt transportation equipment, high-power lifting equipment, etc. Due to the large number of equipment in the multi-motor fleet, strict application requirements are put forward for the safety, reliability and automation level of multi-motor drive control. [0003] In the existing technology, the control method for multi-motor clusters is relatively simple, and the multi-motor system is controlled by relying on the load self-balancing method, that is, the intervention of the source of motor control is less, and the common belt conveyor equipment relies on the soft connection of the belt The independent power balan...
