Wind motor shielding cover, what is the role of shielding cover in transformer + 15 years of experience, the manufacturer tells you

The hardware technicians of the manufacturer of the wind motor shielding cover said that the shielding cover is also called magnetic shielding. It is generally made of magnetically conductive materials. The better one is permalloy, but the price is expensive. Generally, magnetically conductive silicon steel is used. Manufactured with tape or iron, what role does the shielding cover play in the toroidal transformer? Xiaoshuo will come to understand with you: The toroidal transformer with shielding cover has small magnetic leakage and low interference. For power amplifier transformers, electromagnetic interference can be largely eliminated. The sound quality is quite pure and noise-free. It is mainly used for magnetic shielding, effectively reducing the interference of magnetic field on circuits and electronic components. Hardware, 15 years of focusing on wind motor shields, 20,000+ sets of mold custom processing and production experience, monthly processing of 100+ sets of molds, daily production capacity of 3 million punches, stamping accuracy up to 0.01mm, and 16 quality inspections. It can quickly solve time-critical problems for you, solve stamping accuracy problems, and solve mass production quality problems. Choose, choose rest assured!
