Title: Takahito Ishino: Innovator in Motor Control Technology
Introduction
Takahito Ishino is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of motor control technology, holding 2 patents that showcase his innovative approach to improving motor systems.
Latest Patents
His latest patents include a "Motor Control Device and Motor System" aimed at enhancing the identification precision of a motor constant that controls a motor through vector control. This invention involves a parameter identifier that sets an offset voltage of a DC component as a first d-axis target voltage, detecting a d-axis current that flows accordingly as an offset current. The parameter identifier also sets a voltage obtained by superimposing an identification signal of a predetermined AC component on the first d-axis target voltage as a second d-axis target voltage, allowing for the detection of the d-axis current that flows accordingly. The motor constant is identified using a voltage obtained by subtracting the first d-axis target voltage from the second d-axis target voltage and a current obtained by subtracting the offset current from the d-axis current as inputs.
Another notable patent is the "Motor Driving Device, Method, and Program," which encompasses both an initial position determination process and a rotation driving process. This invention features a motor with a rotor that has a permanent magnet with multiple magnetic poles and a stator equipped with coils of various phases. A voltage signal generation part produces a voltage signal corresponding to the electric current flowing through each of the coils. The filter part includes a first filter and a second filter, with the voltage signal being inputted to a comparator through this filter part. The control part is designed to select the first filter with a larger filter constant during the initial position determination process of the rotor, while the second filter with a smaller filter constant is selected during the rotation driving process.
