Latest Patents

One of his latest patents is a motor control device. This device includes a controller that outputs a PWM control signal for managing a multiphase electric motor. It features a driving signal generator that produces a switching element driving signal, which is essential for operating the multiphase electric motor according to the PWM control signal. Additionally, a bridge circuit composed of multiple semiconductor switching elements is designed to switch the current flowing through the motor based on the generated driving signal. The controller is situated on a first board, while the driving signal generator and bridge circuit are located on a second board, interconnected by wiring. The controller effectively communicates with the driving signal generator through a predetermined inter-board connecting line.

Another significant patent by Yamanaka is a magnetic pole direction detection device. This device involves a detecting target magnet attached to the tip of a rotating shaft of the rotor. A magnetic detection unit outputs a detection signal that varies with changes in the magnetic field. The magnetic pole direction calculation unit then calculates the magnetic pole direction of the rotor based on this detection signal. Furthermore, a current detection unit monitors the current flowing through each multiphase coil, while a rotating magnetic field vector calculation unit computes the vector of the rotating magnetic field based on the detected current's magnitude. A direction correction amount calculation unit determines a correction amount based on the direction and magnitude of the rotating magnetic field, which is then used by a magnetic pole direction correction unit to adjust the calculated magnetic pole direction.
