Why is amorphous alloy transformer a good choice?
However, due to magnetostrictive coefficient of the amorphous alloy material is relatively large, the vibration level of amorphous alloy transformer is great, and the noise is sharper than traditional silicon steel transformer.
What is amorphous alloy?
As a new type of soft magnetic material, amorphous alloy has excellent electromagnetic properties (high permeability and low loss) . The application of amorphous alloy material to HFT core instead of conventional silicon steel sheet can significantly reduce the iron loss and improve efficiency.
Does amorphous material have more magnetostriction than silicon steel?
Through the vibration measurement of silicon steel (B30P105), amorphous (1 K101) and nanocrystalline (1K107B) magnetic rings and the calculation of magnetostriction of three kinds of magnetic materials, the results show that the magnetostriction of amorphous materials is much larger than that of silicon steel and nanocrystalline.
Does amorphous alloy HFT have a vibration mechanism?
The general working condition of amorphous HFT is under non-sinusoidal excitation, so the vibration mechanism is more complex than traditional transformer. However, there is lack of vibration and noise studies of amorphous alloy HFT in detail.
Does amorphous HFT increase noise?
The vibration and noise of amorphous HFT increases with the increase of excitation frequency and magnetic flux density. The noise of HFT under high excitation frequency and large magnetic flux density is extremely sharp. Therefore, it is necessary to study its noise reduction measures.
Does magnetostriction affect vibration of amorphous fluxgate sensor?
Hsu Chang-Hung has studied the influence of magnetostriction on core loss, noise and vibration of amorphous fluxgate sensor . The general working condition of amorphous HFT is under non-sinusoidal excitation, so the vibration mechanism is more complex than traditional transformer.
