Document Type and Number:
WIPO Patent Application WO/2023/163153
Kind Code:
A1
Abstract:
This maglev electric motor 10 comprises: a fixed permanent magnet part 20 provided to a casing 11; and a rotating permanent magnet part 30 provided on a rotating shaft 12 so as to face the fixed permanent magnet part 20, the rotating permanent magnet part 30 contactlessly supporting the rotating shaft 12 in a radial direction orthogonal to an axis C using repellent force with respect to the fixed permanent magnet part 20. The fixed permanent magnet part 20 has a pair of first fixed permanent magnets 21 that are radially magnetized, and a pair of second fixed permanent magnets 22 that are radially magnetized in the opposite direction from the first fixed permanent magnets 21. The rotating permanent magnet part 30 has a pair of first rotating permanent magnets 31 that are radially magnetized in the opposite direction from the first fixed permanent magnets 21, and a pair of second rotating permanent magnets 32 that are radially magnetized in the opposite direction from the second fixed permanent magnets 22.
