Abstract

The invention designs a new type of motor controller. The motor controller adopts modular structure design. The whole structure of the motor controller is divided into three parts: a shell, a control module, and a current conversion module. The motor controller has the advantages that the structure is compact, and the assembly is simple and the like.

Description

technical field [0001] The invention relates to the technical field of motor control, in particular to a motor controller for electric vehicles. Background technique [0002] As one of the three core components of an electric vehicle, the design technology of the motor controller plays a decisive role in the operation performance of the entire electric vehicle. At present, there are many motor controller products on the market, many of which are automotive-grade motor controllers, but the following problems generally exist: [0003] 1. Unreasonable structural design, large space occupation and low power density; [0004] 2. The structural modularity of the components inside the controller is low, and the assembly process is relatively complicated, which is not conducive to problem research or maintenance. Contents of the invention [0005] The purpose of the present invention is to design a motor controller to solve the problems of poor structure compactness, low degree ...
