Universal motor controller assembly, parallel single-motor controller and dual-motor controller

Abstract

The embodiment of the invention discloses a universal motor controller assembly, a parallel single-motor controller and a double-motor controller, and the controller assembly comprises a box body, and a shielding plate, a bus capacitor, a bus copper bar, a DC wire holder and a PCB assembly which are integrated in the box body, and also comprises two groups of IGBT module assemblies and an AC output wire holder which are arranged in the box body, the IGBT module assembly is composed of three IGBT modules, two sets of alternating-current wire holder grooves are formed in the box body, and one alternating-current output wire holder is arranged in one set of alternating-current wire holder grooves. The single-motor controller and the double-motor controller are connected in parallel, can be developed as a product, share molds and materials, and can be applied as two independent products at the same time, so that the material types are greatly reduced, the inventory pressure is reduced, and the flexibility of production operation is improved; and the competitiveness of various indexes such as the cost, the power density, the capability, the service life and the reliability of the product is not influenced.

Description

technical field [0001] The invention relates to the technical field of new energy vehicles, in particular to a general motor controller assembly, a parallel single motor controller and a dual motor controller. Background technique [0002] With the rapid development of new energy vehicles, the demand for high-power motor controllers and dual-motor controllers is also increasing. The IGBT module is the core power device of the motor controller. When the power of the general IGBT module on the market cannot meet the demand, it is necessary to use two sets of IGBT modules in parallel to achieve the required power. The dual-motor controller, that is, the controller has two sets of power outputs to control two motors, so two sets of IGBTs are needed to form two inverter modules. Dual-motor controllers are mostly used in power schemes such as wheel rims and hybrids. [0003] The current common motor controllers have the following two problems: [0004] 1) The single-motor contr...

AI Technical Summary

Problems solved by technology

[0004] 1) The single-motor controller and the dual-motor controller are two independent products, and corresponding development resources for the two products need to be invested

[0005] 2) The single-motor controller and the dual-motor controller are two independent products, which need to invest in the cost of two product molds, and the amount of each part is not large, and the batch cost of parts is difficult to control

[0006] 3) The single-motor controller and the dual-motor controller are two independent products, and the corresponding management costs of material coding and products are relatively large
