Abstract

The invention discloses a synchronization control method and device for driving motors. The method comprises the steps of determining the current state of an injection molding machine as a glue injection state, and controlling a sensor to acquire the current position data of each driving motor in a plurality of driving motors; determining a control strategy for controlling the plurality of drivingmotors according to the current position data of each driving motor in the plurality of driving motors; and carrying out synchronization control on each driving motor in the plurality of driving motors according to the control strategy. According to the invention, the technical problem of low reliability of the injection molding machine caused by asynochronization of two motors of a motor multi-drive system in the prior art is solved.

Description

technical field [0001] The invention relates to the technical field of motor control, in particular to a synchronous control method and device for driving a motor. Background technique [0002] In traditional injection molding machine control, the injection movement process is a very important content. Because the injection movement is frequent and often requires a lot of power. However, the current high-power motors are huge and expensive, and cannot meet the design requirements. Therefore, it is often necessary to use two motors for multi-drive system control to solve this problem. However, in general multi-drive systems, it is difficult to achieve synchronous rotation of multiple motors, which will lead to position deviation, motor overload alarm, and more serious damage to the mechanical structure. [0003] Aiming at the problem that the two motors in the motor multi-drive system in the related art are likely to be out of sync, resulting in low reliability of the injec...
