ULTRAHIGH SPEED MOTOR-GENERATOR

摘要

PURPOSE:To enable the generation of a power with high efficiency through endurance with a high speed, by a method wherein an alternating magnetic field of high frequency from the permanent magnet of a rotor coupled directly with an exhaust turbine is converted into a power by means of a rotor winding having a ferrite core serving as a magnetic core. CONSTITUTION:A turbine impeller 9 is rotated at a high speed by energy of exhaust gas fed to a scroll 10 to rotate a shaft 6, and a rotor 13 and a compressor impeller 8 are rotated. In which case, the compressor impeller 8 converts air, introduced through a suction pipe 11, into a pressure with the aid of a diffuser 12, and the air is fed with a pressure to a cylinder to increase an engine output. Meanwhile, rotation of the rotor 13 produces rotation of a permanent magnet having three or more pairs of N - S magnetic poles, and lines of magnetic force are interlinked to a stator winding 16 formed to a stator core 15 to generate an electromotive force. In this case, since the magnetic core of the stator core 15 is formed with a ferrite core excellent in high frequency properties, an alternating magnetic field can be converted into a power with high efficiency.
