Title: Takafumi Satou: Innovator in Rotation Angle Detection and Motor Control
Introduction
Takafumi Satou is a prominent inventor based in Okazaki, Japan. He has made significant contributions to the fields of rotation angle detection and motor control. With a total of 10 patents to his name, Satou's work has had a considerable impact on technology and engineering.
Latest Patents
One of Satou's latest inventions is a rotation angle detector. This device features a rotation angle sensor and a microcomputer. The sensor detects changes in the magnetic field of a magnet that rotates with a shaft. The microcomputer includes a first corrector that adjusts a pre-correction mechanical angle based on a first correction value. This value corrects errors arising from the assembly process of the magnet and sensor. Additionally, a second corrector adjusts the pre-correction mechanical angle based on a second correction value, which accounts for errors due to spill magnetic flux generated by electric current supplied to a winding wire. This innovative configuration allows for accurate detection of mechanical angles.
Another notable invention is a motor control apparatus. This apparatus operates a power conversion circuit that connects a direct current power source to a motor. It performs mutual conversion between power at the direct current source and power at the motor during powering and regenerative operations. The motor control apparatus includes a voltage command calculator that computes a voltage command for the power conversion circuit. It also features a suppression gain calculator that ensures the absolute value of the power source current does not exceed a target value. The voltage command suppressor then adjusts the voltage command by applying the suppression gain.
