Title: Minoru Hamamura: Innovator in Servo Motor Control Technology
Introduction
Minoru Hamamura is a distinguished inventor based in Shizuoka-ken, Japan. He has made significant contributions to the field of servo motor control, holding a total of 15 patents. His innovative approaches have advanced the technology used in various industrial applications.
Latest Patents
One of Hamamura's latest patents is a servo motor controlling method. This method involves detecting the position of a moving body that performs a circular-arc interpolation feeding motion by a servo motor. It includes feedback control to ensure the moving body's position aligns with a position command. Additionally, during quadrant changes, torque correction is applied to the torque command value based on the distance from the position where the direction changes. This method effectively corrects quadrant protrusion and torque changes caused by friction during the reversion of a ball screw. By implementing a first torque correction for static friction and a second for moving friction, the method achieves more precise control.
Another notable patent is a numerical control device that features a parameter memory section. This section stores discrete optimum parameters for various operational modes. The device allows users to select operational modes through a setting switch and includes a defect content setting means for registering defect contents of machined results. The optimum parameter suited for the selected operational mode is retrieved for parameter setting, enhancing the device's functionality.
