Description

Technical Field

[0001] This utility model relates to the technical field of six-phase motor controller housings, and in particular to a one-piece cast dual six-phase motor controller housing. Background Technology

[0002] The main function of a six-phase motor controller is to control and manage the operation of a six-phase motor. It utilizes power electronics, microcontroller, and sensor technologies to achieve precise motor control, ensuring efficient operation and stable output.

[0003] Currently, the mounting feet on dual six-phase motor controllers are fastened to the housing by bolts. This method not only involves many installation steps but also has poor reliability. The stress point is limited to the bolts, reducing the stress range of the housing. Dual six-phase motor controllers are much larger and heavier than ordinary three-phase controllers, and have higher requirements for reliability and stability. The bolt-locking method is difficult to meet the requirements of existing dual six-phase motor controller housings.

[0004] Based on the above background, a one-piece cast dual six-phase motor controller housing is proposed to solve the problem. Utility Model Content

[0014] In some embodiments, grounding points are provided on both sides of the shell body.

[0015] In some embodiments, capacitor heat dissipation surface protrusions are installed on the module partition.
