Blockage of hollow strands' waterway can cause cooling-water flux decreasing, cooling effect falling and stator bar overheating in water-cooling turbo-generators, which could induce generators not to operate normally. It helps to calculate precisely temperature field of generators and diagnose incipiently the plugging fault of cooling-waterway that one study fluid characteristic of cooling-water on hollow strands blocked in turbo-generators. In accordance with generators structure and computational fluid dynamics (CFD), the cooling-water fluid field of turbo-generators stator was studied when the cooling waterway was blocked. Velocity field of cooling-water was researched by applying finite element method(FEM) when the hollow-strands were blocked in different positions and plugging extent. The paper analyzed influence of blockage site and extent on flow characteristic of water in hollow strands. The achievement can be used for calculation of temperature filed and early diagnosis of blockage fault in generators.

Switched reluctance motor (SRM) has many specific advantages and has being gradually used in all kinds of applications. However, because it's inherently multivariable, strong-coupling and highly nonlinear, there are lots of difficulties to build its model. In this paper, many modeling methods include numerical, analytical and intelligent approaches are studied and compared in terms of complexity and accuracy. The static flux linkage and torque characteristics obtained by each method are given. The advantages and disadvantages of each method are summarized as well.

The purpose of this paper is to contribute to the high-speed aspect of flux switching permanent magnet machine by performing detailed electromagnetic design, performance evaluation, and trade-off comparisons. Topologies with multiple numbers stator slot/rotor pole combinations are analyzed, and their challenges for high-speed operation are discussed. The topology with 12 stator slots and 10 rotor poles is analyzed in detail including loss characterization. Properties of iron loss, especially the eddy current loss, are analyzed using fast Fourier transformation. Magnet eddy current loss is studied at high-speed conditions for neodymium magnets. Axial magnet segmentation is found to be effective for reducing the magnet eddy current loss. Windage loss of the rotor also is estimated using analytical methods and it cannot be neglected for high-speed operations.
