MAGNETIC FLOATING TYPE DYNAMO-ELECTRIC MOTOR AND MAGNETIC FLOATING TYPE PUMP

Japanese Patent JP2023125645

A

To provide a magnetic floating type dynamo-electric motor that actively controls a one shaft to a thrust direction, capable of securing a supporting force to a radial direction, and enhancing the support force of the thrust direction.SOLUTION: A magnetic floating type dynamo-electric motor 10 comprises: a fixing permanent magnet part 20 that is provided to a casing 11; and a rotational permanent magnet part 30 that supports a rotational shaft 12 in non-contact to a radial direction orthogonal to a shaft line C by a repulsive power with the fixing permanent magnet part 20 so as to be oppositely provided to the fixing permanent magnet part 20 in the rotational shaft 12. The fixing permanent magnet part 20 includes: a pair of first fixing permanent magnets 21 that is magnetized to the radial direction; and a pair of second fixing permanent magnets 22 that is magnetized in the opposite direction to the first fixing permanent magnets 21 in the radial direction. The rotational permanent magnet part 30 includes: a pair of first rotational permanent magnets 31 that is magnetized to an inverse direction with the first fixing permanent magnets 21 to the radial direction; and a pair of second rotational permanent magnets 32 that is magnetized to an inverse direction with the second fixing permanent magnets 22 to the radial direction.SELECTED DRAWING: Figure 2
