Title: Takeo Tsukamoto: Innovator in Motor Control Technology

Introduction

Takeo Tsukamoto is a notable inventor based in Isesaki, Japan. He has made significant contributions to the field of motor control technology, holding three patents that showcase his innovative approach to enhancing motor performance and efficiency.

Latest Patents

One of Tsukamoto's latest patents is a motor control device designed to determine rotor position with high accuracy. This device operates effectively in both normal control and flux-weakening control scenarios. It features a first rotor position determining unit that utilizes a rotor position calculation formula based on current electrical angle or induced voltage electrical angle. Additionally, it incorporates a second rotor position determining unit that also employs a rotor position calculation formula, but with different parameters. A selecting unit is included to choose between the first or second rotor position determining unit based on the operational requirements.

Another significant patent by Tsukamoto is a motor control device capable of executing a start mode that considers both the start performance concerning a residual load and the longevity of the drive circuit. This device stores a current value at the moment a stop command is issued to a synchronous motor. When a start command is later given, it determines a target current value based on the previously stored current value, ensuring optimal performance during the start mode.
