摘要： The present disclosure relates to a downhole rotating magnetic field generator, wherein a stator assembly is formed by fixedly connecting a guiding stator, windings, and a body together, and a rotor assembly is formed by mounting a turbine rotor and a permanent magnet together. Between the stator assembly and the rotor assembly, sliding bearings are arranged and small mud passages are formed. There is no metal isolation between the rotor and the stator for cutting through the magnetic lines of force, so that the eddy current loss is relatively small. Meanwhile, with mud flowing through the passages as lubricant, overheating of the generator can be prevented and high power output can be ensured.
摘要翻译： 本发明涉及一种井下旋转磁场发生器，其中通过将引导定子，绕组和主体固定地连接在一起而形成定子组件，并且通过将涡轮转子和永磁体安装在一起而形成转子组件。 在定子组件和转子组件之间，设置滑动轴承并形成小的泥浆通道。 在转子和定子之间没有金属隔离来切割磁力线，使得涡流损耗相对较小。 同时，由于泥浆作为润滑剂流过通道，因此能够防止发电机的过热，能够确保高功率输出。
