Introduction

Makoto Akama is a notable inventor based in Kitakyushu, Japan. He has made significant contributions to the field of motor control technology. With a total of 3 patents to his name, Akama's work has advanced the efficiency and functionality of motor control devices.

Latest Patents

One of Akama's latest patents is a motor control device that includes a main circuit, a voltage detector, and a controller. The controller features both a position controller and a speed controller. The position controller generates a speed command, while the speed controller generates a torque command and controls an inverter based on that command. Additionally, the controller incorporates a torque limiter that initiates torque limiting to a predetermined torque or less. It also includes a speed matching instruction part that aligns the speed command with a first position command speed after the torque limiting is canceled.

Another significant patent is a motor control apparatus that also includes a controller with a position controller and a speed controller. This controller is designed to manage the inverter based on the torque command. It features a torque limiter that starts first torque limitation when the voltage detector identifies that the DC voltage falls below a predetermined level. The torque limitation is canceled when the voltage exceeds this threshold. Furthermore, the controller includes a speed limiter that restricts the commanded speed based on the speed command.
