Nanocrystalline Cores for Energy Switching

Amorphous alloy materials   are known for energy saving. Amorphous power transformers have lower core losses than silicon steel transformers, but the magnetostriction coefficient of amorphous alloys is large, which will result in greater core vibration of the amorphous transformer during operation, and the noise level varies The increase. Electromagnetic vibration not only affects the service life of equipment, but also causes more and more attention to the noise environment. Therefore, how to design and manufacture amorphous power transformers with low vibration and noise has become an urgent problem to be solved in its promotion and application. Scientists measured the magnetic properties of the amorphous strip and the amorphous wound core respectively, and obtained the magnetization and magnetostrictive properties of the core under different clamping forces. Based on the measurement data, the magnetic field and stress vibration of the amorphous iron core under different clamping...
