Outside, also to guarantee that iron core has certain dress compaction degree, generally use stacking factor to guarantee the relationship between pressure and weight.Iron
The axial pressing force of core is usually that the tooth support by two sides and the stretching screw across iron core are generated and maintained.Due to using upper
The design stated, so that stretching screw is equivalent to single line stick on iron core, this root bar equally can under rotating excitation field effect
Generate induced potential.Induced electromotive force is smaller under normal circumstances, and when stretching screw insulate qualification, stretching screw will not be with iron core
Galvanic circle is formed, generator can operate normally.When stretching screw insulation values are zero, it will folded in stretching screw, iron core
Piece, positioning bar form current loop, increase the iron core temperature near short-circuit loop sharply, while the formation of two short dots
The vortex that will cause iron core increases, and accelerating stator coil aging speed reduces service life, be enough to burn out when serious iron core and
Fuse stretching screw.
In conclusion stretching screw plays an important role to the stacking factor of iron core, while there is also serious security risks.
