0 Introduction motor air gap magnetic field motor design is an important research topic. However, permanent magnet salient pole synchronous generator (hereinafter referred to as a "rare-earth permanent magnet generator"), the pole shoe gap directly affects the shape of the distribution of the magnetic field waveform. In an effort to load air-gap permanent magnet generator sine wave distribution of the magnetic field close to the lower voltage sinusoidal waveform distortion Ku, improve operational performance, explore the shape of rare earth permanent magnet generator pole shoe design is very necessary. A rare earth permanent magnet generator air-gap magnetic field characteristics of rare earth permanent magnet generator and electrical properties of the air gap magnetic field excitation salient pole synchronous generator (hereinafter referred to as "excitation generator"), the different nature of the air gap magnetic field, the armature the effect of reaction are different. Therefore, the magnetic poles of the pole shoe shape design parameters are different. First, the electric excitation hair .
The air gap magnetic field characteristic of rare earth permanent magnet salinet-pole synchronous generator is studied. Based on the actual tested no-load air gap magnetic field waveform of typical prototype and the voltage waveform sine distortion rate, the affect of the pole shape to the no-load air gap magnetic field waveform, the voltage waveform sine distortion rate and the steady voltage adjusting rate are expounded. And the pole shape of rare earth permanent magnet salient-pole synchronous generator is discussed.

Why only one salient pole synchronous generator synchronous reactance, and salient generator with quadrature axis synchronous reactance and the direct axis synchronous reactance of the points it reward points: 0 | solution time :2010-10-20 21:02 | Asked by: Card Mi Kami Buddhists best answer
Is implicit because the generator rotor pole, rotor pole no matter which angle is round, so the reactor is only one value. The turbine rotor is usually convex pole, very center of the gap with the stator core minimum (straight shaft), and two pole position between the large gap with the stator core (cross-axis), both in the electric angle 90 degrees on the difference, it has two different reactance values. 0 answers help me time :2010-10-20 20:37 | I have to comment to the TA for help
