Title: Erisha Hayashi and Machine-Tool Control Innovation.
Introduction
Erisha Hayashi is an inventor associated with Nagano, Japan. His patent work addresses machine-tool control, with a focus on managing servo-motor power consumption during machine operation.
Latest Patents
Hayashi is named on 1 patent: “Machine Tool and Control Device for Machine Tool.” The invention describes a machine tool with a main-spindle driver, a servo motor that drives a machining tool, a power source, a current detector, storage for a current limit, and a controller.
When the detected servo-motor current exceeds the stored upper limit immediately after the main spindle starts, the controller changes the acceleration/deceleration time constant from a first setting to a second setting designed to use less power. This control approach aims to manage power consumption while operating the tool.
Career Highlights
Hayashi is associated with Citizen Watch Co., Ltd. and Citizen Machinery Co., Ltd. His patent reflects work related to machine tools and their control systems.
Collaborations
The patent concerns components working together within a machine tool, including the spindle driver, servo motor, current detector, storage, and controller. The available information does not specify individual co-inventors or other collaborators.
Conclusion
Erisha Hayashi’s patent documents a machine-tool control approach that responds to elevated servo-motor current by adjusting the acceleration/deceleration time constant to reduce power consumption.
