Permanent magnet suspension direct-connection advection micro-water generator

The utility model discloses a permanent magnet suspension direct-connection advection micro-water generator which comprises a float bowl, a magnetic bearing, a bearing support, an impeller, a generator main shaft and an iron-core-free permanent magnet generator, and the iron-core-free permanent magnet generator comprises a rotor disc and a stator disc. The two bearing supports are installed at thetwo ends of the buoy respectively. The number of the magnetic bearings is two, the two magnetic bearings are installed on the two bearing supports respectively, and the two ends of the generator mainshaft are connected with the two magnetic bearings respectively. Wherein the coreless permanent magnet generator is installed on the generator main shaft, and the impellers are sleeved and fixed on the generator main shaft and can drive the generator main shaft to rotate synchronously. The wind power generation device is simpler in structure, capable of being started easily and generating power efficiently and lower in co
