| 摘要 |
The present invention relates to an underwater thruster of a small-sized unmanned underwater vehicle, which makes waterproofing physically simple and easy and makes maintenance and repair unnecessary for a long period of time. The present invention comprises a motor having a first magnetic body electrically connected to a battery equipped within a hull of the small-sized unmanned underwater vehicle and coupled to an end of a first power shaft to which generated power is transmitted; a motor case accommodating a motor and including a shielding film spaced from the magnetic body at a regular interval for shielding the motor from the outside; and a duct arranged coaxially with the first power shaft, having a rear end equipped with a second magnetic body receiving the rotational force of the first power shaft via the first magnetic body and having a front end accommodating a second power shaft where a propeller rotating by the rotational force transmitted from the first power shaft is installed. |
