Wind power generator, magnetic pole laminate for synchronous generator of wind power generator, and synchronous generator

摘要

Smoothing vibrations that cause generator torque fluctuations and resulting equipment damage and undesirable noise generation, or at least affect the frequency of superimposed and generated vibrations from such vibrations, thereby Minimize the frequency of vibrations involved. A wind power generator comprising a synchronous generator, in particular a ring generator, wherein the synchronous generator has a power of at least 500 kW, a gap diameter of at least 3 m, and one stator and one rotor. The rotor includes a plurality of magnetic pole stacks (10), each magnetic pole stack (10) includes a plurality of magnetic pole stacks (22), and each magnetic pole stack (22) Including one pole shaft region (20) and one pole head region (18), the pole head region (18) projecting laterally beyond the pole shaft region (20), and the pole head region (18) has a side (32) facing the pole shaft region (20) and a side (30) opposite to the pole shaft region (20), and the contour (31) of the pole head region (18). ) At least the pole shaft region ( 0) is an elliptical shape at the opposite side (30) is equal to or elliptical orbit.
