Title: Syuzou Iwaasa and His Submerged Motor Stator Patent.
Introduction
Syuzou Iwaasa is an inventor associated with Hitachi, Ltd. in Hitachi, Japan. His patent work includes an invention concerning the design and construction of a submerged motor stator.
Latest Patents
Iwaasa is credited with 1 patent: “Stator of Submerged Motor.” The invention describes a stator using highly precise cylinders made from carbon fiber reinforced plastics. To strengthen the joints between the inner cylinder and the end covers, the design increases the inner cylinder’s wall thickness near both axial ends. One thicker portion is on the outer surface, while the other is on the inner surface. The central section remains thinner, helping reduce eddy current loss, while the reinforced ends improve mechanical strength and support reliable joining.
Career Highlights
Iwaasa’s documented patent contribution focuses on balancing electrical efficiency with structural strength in submerged motor stators. The design addresses both eddy current loss and the practical challenge of joining composite cylinders to end covers.
Collaborations
The provided information identifies Kenzo Kadotani and Yutaka Higashimura as Iwaasa’s coworkers. Their names are associated with his professional context at Hitachi, Ltd.
Conclusion
Syuzou Iwaasa’s patent presents a targeted stator design that combines a thinner central cylinder with reinforced ends to support efficiency, strength, and dependable assembly.
