Circumferential multi-motor driven annular electric propeller supported by water-lubricated bearing

The utility model relates to a water-lubricated bearing supported annular electric propeller driven by multiple motors in the circumferential direction. The water-lubricated bearing supported annularelectric propeller comprises a shell, a motor driving unit, a water-lubricated bearing system and a propeller. The annular electric propeller is supported by a water-lubricated bearing system and is jointly driven by a plurality of linear motors, adverse effects caused by magnetic bearings can be eliminated, the propeller is simple in principle and structure, high in propelling efficiency, low invibration noise, high in safety and redundancy and low in starting current, and the service life of the propeller is prolonged. The device is especially suitable for ships with inland river and lake shallow draft environment limitation. 本实用新型涉及一种水润滑轴承支撑的周向多电机驱动的环形电力推进器，包括：壳体、电机驱动单元、水润滑轴承系统和螺旋桨。本实用新型为水润滑轴承系统支撑的、由多个直线电机联合驱动的环形电力推进器，可以消除磁轴承带来的不利影响，本推进器原理和结构简单、推进效率高、振动噪声低、安全性和冗余度高、启动电流低，尤其适合于内河和湖泊浅吃水环境限制的船舶。
