Rigid-flexible coupling multi-motor system

Abstract

The invention discloses a rigid-flexible coupling multi-motor system. The rigid-flexible coupling multi-motor system comprises an upper computer, a main controller, a first motor driver, a first torque sensor, a first motor, a first encoder, a second motor, a second encoder, a second torque sensor, a second motor driver, a second driving roller, a tension sensor, a belt, a first driving roller, arigid coupling, a third torque sensor, a third motor, a third encoder, a third motor driver, a connecting shaft and a signal wire, wherein the two motors are rigidly and coaxially connected to achieverigid coupling between the two motors; the two motors are connected by adopting belts at two ends, so that the rigid-flexible coupling connection between the two motors is achieved; and the physicalexperiment research of the coaxial connection of the belt conveyor and the double motors driven at two ends is achieved at the same time.

Description

technical field

[0001] The invention relates to a rigid-flexible coupling multi-motor experiment system, which belongs to the field of electromechanical control. Background technique

[0002] In industry, for some large inertia loads driven by motors, such as cement kilns, paper machines, belt conveyors, etc., in order to increase the flexibility of the system structure, reduce the size of the motor, and reduce energy consumption, two or more sets are often used The motors are driven in concert. In a multi-motor system with coupling relationship, whether each motor unit can run safely and reliably directly affects the production efficiency and product quality of the entire moving body, and even affects production safety. Therefore, the study of multi-motor systems has important academic value and extensive application background.

[0003] At present, multi-motor systems can be divided into no physical connection, rigid physical connection, flexible physical connection and ...
