Title: Kota Fukuda: Innovator in Magnetostrictive Sensors
Introduction
Kota Fukuda, an accomplished inventor based in Shizuoka, Japan, has made significant contributions to the field of magnetostrictive technology. With a total of nine patents to his name, Fukuda has demonstrated expertise in the development of advanced sensor systems, particularly in torque sensors.
Latest Patents
Among his latest inventions is a method of manufacturing a magnetostrictive torque sensor shaft. This innovative method involves several key steps, including a heat treatment process that subjects an iron-based shaft member to carburizing, quenching, and tempering. A notable aspect of his method is the shot peening procedure, which employs boron-free zirconia shot media. This ensures that the shaft member, after heat treatment, achieves a total error of no more than 3%, incorporating both hysteresis error and angle error.
Additionally, Fukuda developed a magnetostrictive torque sensor that features detection coils formed around a magnetostrictive material, which may be constructed from chrome steel or chrome molybdenum steel. This sensor design also includes a magnetic ring that covers the detection coils and a drive unit that provides alternating current excitation at specific frequencies. The thickness of the magnetic ring is fundamentally critical, being 1.455 times or more the skin effect thickness of the magnetostrictive material, but not exceeding 1.000 mm.
