Circumferential multi-motor driven electric propeller of liquid suspension bearing

The utility model relates to a circumferential multi-motor driving electric propeller of a liquid suspension bearing. The circumferential multi-motor driving electric propeller comprises a shell, a motor driving unit, a liquid suspension bearing system and a propeller. The propeller is an annular electric propeller which is supported by a liquid suspension bearing system and is jointly driven by aplurality of linear motors, can eliminate adverse effects caused by magnetic bearings, and is simple in principle and structure, high in propelling efficiency, low in vibration noise, high in safetyand redundancy, low in starting current and high in reliability. 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液悬浮轴承的周向多电机驱动电力推进器，包括：壳体、电机驱动单元、液悬浮轴承系统和螺旋桨。本实用新型推进器为液悬浮轴承系统支撑的、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，起原理和结构简单、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。
