Title: Tatsuya Tonari: Innovator in Electric Machine Control
Introduction
Tatsuya Tonari is a notable inventor based in Kariya, Japan. He has made significant contributions to the field of electric machine control, holding a total of 3 patents. His work focuses on enhancing the efficiency and performance of electric motors through innovative control devices.
Latest Patents
One of Tonari's latest patents is a control device for rotating electric machines. This device is designed to suppress the electromagnetic force applied to a motor. It features a harmonic current calculation section that calculates the amplitude and phase of harmonic currents to be superimposed over a fundamental current. This calculation is based on conditions relating to load changes of the motor. The operation section then generates and transmits instruction signals to an inverter, ensuring that the calculated harmonic currents flow in the phase windings of the stator.
Another significant patent is a control apparatus for motors. In this apparatus, a fundamental voltage generator creates a fundamental voltage command based on a target rotational speed. A property storage component retains the natural vibration properties of the rotor while it is rotating. Additionally, a rotating state detector monitors the rotating position and speed of the rotor. Based on this information, a harmonic voltage generator produces a harmonic voltage command to be superimposed on the fundamental voltage command.
