Exhaust turbine driven disk-type double-rotor permanent magnet generator

[0012] Attached below Figure 1-3 The present invention is further described:

[0013] The rotating shaft 1 of the generator and the rotating shaft of the turbine are the same shaft, the front end cover 2 and the rear end cover 3 are both mounted on the rotating shaft 1 with bearings, and the stator consists of a disc-shaped stator bracket 4 that is sleeved on the rotating shaft 1 with a gap and embedded in the rotating shaft 1. The stator bracket 4 is composed of a plurality of iron cores 6 wound with armature windings 5, wherein the iron cores 6 are evenly distributed on the same circumference of the stator bracket 4, and the number of turns of each armature winding 5 is equal, and the number of turns of the stator bracket 4 is equal. The outer edge is clamped and fixed by the front end cover 2 and the rear end cover 3, and the stator bracket 4 is coaxial with the front end cover 2 and the rear end cover 3; a disc rotor is added on both sides of the stator bracket 4, and each disc rotor is It includes a rotor disk 7 fixedly sleeved on the rotating shaft 1 and a plurality of rotor magnets 8 fixed on the rotor disk 7, wherein the plurality of rotor magnets 8 fixed on the same rotor disk 7 are all fixed on the disk type by screws 10. The rotor is close to the end face of the stator bracket 4 and is located on the same circumference, the polarity of the adjacent rotor magnets 8 facing the end face of the stator bracket 4 is opposite, and there is a certain axial gap between the two disc rotors and the stator.
