Abstract: Disclosed is a radial-axial air gap three-phase disc-type transverse flux permanent magnet motor. Each phase includes a stator consisting of shoe-shaped stator cores and shoe-shaped permanent magnets, and a radial-axial rotor. The permanent magnets are magnetized in the circumferential direction, and the magnetization directions of the two adjacent permanent magnets are opposite to each other. Armature windings are wound in the grooves formed by the alternately arranged stator cores and the permanent magnets. The radial-axial rotor includes radial teeth, axial teeth, and right-angled yokes. The radial teeth are connected to the axial teeth through the right-angled yokes. Adjacent radial/or axial teeth are spaced at a mechanical angle of 360/n degrees. Radial teeth and the adjacent axial teeth under the same pole pairs are spaced at a mechanical angle of 180/n degrees, where n is the number of pole pairs of the radial-axial air gap three-phase disc-type transverse flux permanent magnet motor.

Abstract: A buoy-type high-frequency ground wave radar system. A buoy platform is used as an offshore carrier of a ground wave radar. A sky wave emission subsystem is disposed on a shore base and emits a high-frequency electromagnet wave. After the high-frequency electromagnet wave is refracted by the ionosphere and is reflected by the sea surface, a sky wave signal is formed. An attitude measurement subsystem measures and acquires attitude data of the buoy platform in real time. A ground wave radar subsystem receives a ground wave signal by using the ground wave radar, and processes the signal to form a ground wave doppler spectrum. Simultaneously, the sky wave signal is received, ionosphere disturbance compensation is performed on the sky wave signal in a frequency domain and then the sky wave signal is processed to form a sky wave doppler spectrum.
