An underwater linear transport system provided with a vehicle (1) running along a track (2) in the water. The vehicle (1), with its dead weight slightly different from its buoyancy, has a tightly sealed construction and is supported on and movable along the track (2). The primary side (4) of a linear induction motor is provided on the track (2) while facing the secondary side (6) of the linear induction motor provided on the vehicle (1). There are provided a propelling control means for controlling a propelling force produced by the linear induction motor formed of the primary side (4) and the secondary side (6), and wheels for supporting the difference between the dead weight and the buoyancy of the vehicle (1) on the track (2). In order to reduce the difference between the dead weight and the buoyancy, an electromagnetic force to offset the difference is applied, or, in order to keep constant the length of gap between the conductor on the secondary side and the track (2), an electric current command is issued. <IMAGE> |
