Highly integrated motor control system

Abstract

The invention discloses a highly integrated motor control system and belongs to the TIGBT field. The system comprises a control and drive integrated circuit board, an IGBT module, a capacitor, a three-phase output busbar, a shielding case for a sensor, a three-phase copper bar injection molded part and a radiator for an IGBT; direct connection and interconnection welding processes of different modes are adopted. Compared with a scheme in the market, the system has higher reliability and consistency. The system has the advantages of compact structure, high integration level, light weight, flexible platform expansion and the like; meanwhile, traditional bolt connection and wiring harness connection are omitted in design, and assembling is easier and more convenient; and the system is suitable for automatic batch manufacturing, and provides a technological basis for assembling with a higher automation degree.

Description

technical field [0001] The invention relates to the field of IGBTs, in particular to a highly integrated motor control system. Background technique [0002] The traditional motor control system is generally large in structure and loose in the interior. Usually, it is connected by bolts, wire harnesses, etc., and thermal conductive silicone grease needs to be filled between components, which not only results in large volume and heavy weight, but also generally has a relatively high thermal resistance of the system. Large, reliability is not very ideal. [0003] Moreover, the components are generally small in size, and the assembly of each one, whether it is wiring harness connection or bolting, requires manual operation, and the production efficiency is relatively low, which is not suitable for automated mass production. Contents of the invention [0004] The purpose of the present invention is to provide a highly integrated motor control system, which adopts different met...
