PROPULSION SYSTEM WITH ANNULAR ELECTRIC MOTOR FOR UNDERWATER VEHICLES OF LARGE AUTONOMY Russian patent published in 2020 - IPC B63H1/16 B63H5/00 

FIELD: shipbuilding.

SUBSTANCE: invention relates to ship building, namely, to propulsion devices. Propulsion complex with annular electric motor for underwater vehicles of large autonomy comprises attachment, which is attached to stern cowl by means of pylons and straightening apparatus. In the nozzle there is a synchronous multi-pole motor stator. Monolithic stator filled with rigid compound with inverter power switches integrated therein. Stator has sectioning in longitudinal direction into two identical parts not connected by common magnetic flux. In the propulsion complex, a screw with a hub is used, in which a thrust bearing is installed. On rotor outer annular part rotor assembled of detachable magnetic units is arranged.

EFFECT: higher efficiency in modes of underwater vehicle full stroke.
