Small induction coil

The size parameters of the small induction coil are (mm) inner diameter 15x20; outer diameter 18.5x24, height 3.1; wire diameter 0.2; number of turns 101; inductance 350uh; resistance 4.4 ohm; Introduction The card reader coil is a kind of antenna, and the first function of the antenna is to radiate and receive electromagnetic waves.

The precision requirements of the small induction coil are relatively high, which puts forward higher requirements for the winding method. The common types of winding machines in our country are: fiber winding machine, glass fiber reinforced plastic winding machine, stretch film winding machine, annular winding machine, rectangular winding machine, electromagnetic coil winding machine, trayless winding machine, transformer winding machine, etc. The existing winding machines are mainly used in motor stator coil winding, electrical coil winding and transformer winding coil winding. These devices can realize winding, arranging, hanging A reader-writer coil winding machine is designed, which occupies a small area, has good stability during the winding process, and is easy to adjust.
