Latest Patents

Mori's latest patents include a magnetic pole direction detection device and a polyphase electric motor control device. The magnetic pole direction detection device features a detecting target magnet attached to the tip of a rotating shaft of the rotor. A magnetic detection unit outputs a detection signal that changes according to variations in the magnetic field. This device includes a magnetic pole direction calculation unit that determines the magnetic pole direction of the rotor based on the detection signal. Additionally, it has a current detection unit that monitors the current flowing through each multiphase coil. A rotating magnetic field vector calculation unit computes a vector of the rotating magnetic field based on the magnitude of the detected current. Finally, a direction correction amount calculation unit and a magnetic pole direction correction unit work together to refine the calculated magnetic pole direction.

The polyphase electric motor control device is designed to enhance the efficiency of electric motors. It stores a first threshold as a duty cycle at which noise from a high potential-side switching element begins to overlap a measurement period. It also establishes a second threshold for when a low potential-side switching element transitions from on to off. The device makes judgments by comparing target duty cycles with these thresholds and measures current during specific periods based on these comparisons.
