  • Patent number: 10384753
    Abstract: The present invention is to provide a launcher for an underwater vehicle by which thrust force of a mover arranged movably in a water conducting tube can efficiently be obtained. The mover forms a plurality of magnetic circuits in which magnetic flux generated by a plurality of permanent magnets flows, and the plurality of magnetic circuits includes a first magnetic circuit in which the magnetic flux flows through one of a pair of circumferential magnets, a second magnetic circuit in which the magnetic flux flows through one of a pair of axial magnets, the second magnetic circuit being formed in parallel to the first magnetic circuit, and a third magnetic circuit in which the magnetic flux flows through a radial magnet, the third magnetic circuit being formed in parallel to the first magnetic circuit and the second magnetic circuit, respectively.

  • Patent number: 10381890
    Abstract: An axial gap type dynamo-electric machine (1) comprises: a stator (2) provided with a magnetic core (21) and an exciting coil (22); a rotor (3) provided with a plurality of permanent magnets (4) circumferentially arranged around a rotation center axis (AX), the rotor (3) being also provided with a disk-shaped base material (31) for supporting the permanent magnets, the rotor (3) being disposed at an axial distance from the stator (2); and affixation members (5) for affixing the permanent magnets (4) to the base material (31). The permanent magnets (4) are provided with front surfaces facing the stator (2), rear surfaces facing the base material, and engagement-receiving sections (412, 422, 432) formed at peripheral edges of the permanent magnets (4). The affixation members (5) include: engagement sections (512) engaging the engagement-receiving sections; and affixation sections (511) forming mechanical affixation structures relative to the base material.
