Description

Technical Field

[0001] This invention relates to the field of motor control equipment technology, and in particular to a high-strength integrated motor control box. Background Technology

[0002] With the rapid development of industrial automation, new energy vehicles, and intelligent manufacturing, the requirements for the operational stability, control precision, and integration of motors, as core power components, are increasing. As a key supporting device for motor systems, motor control boxes must simultaneously meet four core requirements: structural protection, integrated installation, lightweight design, and high strength. The shortcomings of existing technologies: Traditional motor control boxes mostly adopt a single box structure with a lack of targeted reinforcement design inside. In industrial vibration, impact or complex outdoor environments, problems such as box deformation and loosening of components are prone to occur, affecting the stability of motor control. The integration level is low, and the power interface, control interface, installation components and other components are scattered, resulting in messy internal wiring, low assembly efficiency, and large space occupation, making it difficult to adapt to the installation requirements of miniaturized and compact equipment.

[0013] Preferably, the wiring rod is in a cylindrical structure, is fixed transversely between the two side walls in the main box, and the number of the wiring rod is at least one, and is distributed in the height direction of the main box.

[0014] Through the above scheme: the cylindrical wiring rod is transversely and interval arranged, which provides an orderly bundling and fixing for the cables, avoids the cables from being wound and worn, does not hinder the utilization of the internal space, and improves the wiring specification and equipment reliability.

[0015] Preferably, a plurality of mounting holes are formed in the installation plate assembly, the mounting holes are distributed in an array, and the hole diameter of the mounting holes is adapted to the fixing bolts of the motor control component.
