Description

Technical Field

[0001] The utility model relates to the technical field of welding equipment, in particular to a device for ultrasonic welding of plastic magnetic cores. Background Art

[0002] Amorphous soft magnetic alloy material is a new type of material that came out in the 1970s. It is known as the new green energy-saving material of the 21st century because of its advantages such as low core loss, high resistivity, good frequency characteristics, and high magnetic induction intensity. Amorphous alloys have no grains and grain boundaries and are easy to magnetize. The power frequency iron loss of amorphous alloys is only 1 / 5 to 1 / 3 of that of silicon steel.
