Introduction

Kazushi Usui is an inventor associated with Fukui, Japan, and Matsushita Electric Industrial Co., Ltd. His patent work includes an innovation in motor stator construction designed to reduce deformation during assembly.

Latest Patents

Usui is credited with 1 patent, titled “Two-piece motor stator.” The invention describes an inner iron stator core with outward-extending teeth and an outer iron stator core with slots that receive the teeth. Coils are placed around the teeth before the two cores are joined by press fitting.

Channels along the slots absorb stress created during press fitting, helping reduce deformation of the stator cores. The patent also describes placing channels in the teeth instead, and optionally filling the channels with a deformable, magnetically soft material.

Career Highlights

Usui’s listed patent reflects work on motor components and manufacturing design. Its focus is on managing assembly stress while maintaining the structure of the stator cores.

Collaborations

Usui’s listed coworker is Genki Kondo. The available information identifies both inventors in connection with the motor stator patent and Matsushita Electric Industrial Co., Ltd.

Conclusion

Kazushi Usui’s “Two-piece motor stator” patent presents a practical approach to reducing deformation during motor stator assembly through stress-absorbing channels.
