Latest Patents

Inoue holds a patent for a rotating electric machine drive system. This system includes a rotating electric machine equipped with a rotor that has one magnetic pole configured by permanent magnets. The rotor also features a salient pole portion that is magnetically convex in a radial direction. Additionally, the system comprises a stator wound with a multiphase stator winding, an inverter for supplying electric power to the stator winding, and a control unit for managing the energization current of the inverters. The control unit is designed to perform energization control of the stator winding, ensuring that a fundamental wave current at a frequency synchronized with the rotor's rotational speed, along with a harmonic current that is triple the fundamental frequency, flows in the stator winding. This innovative approach generates a stator magnetic field with a specified lead or delay phase concerning the rotor's third-order magnetic field.
