Title: Ryunosuke Akimatsu: Innovator in Electric Machine Control
Introduction
Ryunosuke Akimatsu 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 rotating electric machines.
Latest Patents
Akimatsu's latest patents include a "Control Apparatus for Rotating Electric Machine" and a "Control Device for Rotating Electric Machine." The control apparatus features a magnetic flux information acquiring unit that gathers magnetic flux data from the machine's magnetic poles. It also includes a fundamental setting unit that establishes a command value for supplying a fundamental current to the machine's winding. Additionally, a harmonic setting unit sets a harmonic command value to reduce variations in the radial electromagnetic force acting on the rotor. The operating unit then uses these command values to supply the winding with a drive current.
The control device is designed to suppress electromagnetic forces applied to a motor. It consists of a harmonic current calculation section that determines the amplitude and phase of harmonic currents based on load changes. The operation section generates instruction signals for an inverter to ensure that the calculated harmonic currents flow in the motor's phase windings.
