The present invention relates to the field of magnetoelectric technology, in particular to a ring-shaped differential-mode
inductor and a production method thereof. The ring-shaped differential-mode
inductor includes a ring-shaped
magnetic core and a coil, and the ring-shaped
magnetic core is connected by a first
magnetic core and a second magnetic core. In combination, the window in the middle of each turn coil forms a magnetic core channel, and the first and second magnetic cores are inserted into the magnetic core channel and then docked. The production method of the annular differential mode
inductor comprises the following steps: winding the coil by a
winding machine, respectively passing the first and second magnetic cores through the coil, while the second magnetic core is passed through the other end of the coil core channel, and the The starting and
tail wires are stripped and soldered. In the present invention, the coil passes through the magnetic core after being wound by a
winding machine. The winding process is simple, which solves the problem that the wire
diameter is too large and cannot be wound. At the same time, it reduces the labor intensity of workers and improves production efficiency; The
copper wire will be damaged or have pinholes during the process, which improves the yield.
