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.
