Embodiment 1

[0015] like figure 1 The schematic structural diagram of the electromagnetic coil shown includes a permanent magnet core 1 , a cylindrical shell 2 , a conductive coil 3 , and a winding skeleton 4 . The winding frame 4 is wound with a conductive coil 3 and built in the cylindrical casing 2 , and the permanent magnet core 1 is built in the inner hole of the winding frame 4 . The S pole end of the permanent magnet core 1 is provided with a limit rod 7, the end of the limit rod 7 is provided with a right limit retaining ring 6-1, and the N end of the permanent magnet core 1 is provided with a left limit retaining ring 6-2. Both the bobbin 4 and the cylindrical casing 2 are non-magnetic conductors. The S pole of the permanent magnet core 1 is limited between two electromagnetic poles in the conductive coil 3 , and the other magnetic pole N is limited outside the electromagnetic pole of the conductive coil 3 . The conductive coil 3 is connected in the forward and reverse switch ci...

Embodiment 2

[0019] see figure 2 , the permanent magnet core 1 in this example is affixed to a metal magnetizer 1-1 along its magnetic flux direction, one section adopts a permanent magnet, and the other section adopts a metal magnetizer, and the two are affixed together along the magnetic flux direction, which can be Reduce the cost. The limit of the permanent magnet core 1 can be directly controlled by the valve connected to its end. That is, the S pole is limited between the two electromagnetic poles of the conductive coil 3 , and the other magnetic pole N is limited outside the electromagnetic pole of the conductive coil 3 . The conductive coil 3 is connected with the same as the previous example.

[0020] Place and connect a strong permanent magnet at one end of the movable magnetic core to form a movable strong magnetic core, and make the magnetic flux of the strong permanent magnet penetrate through the movable magnetic core longitudinally, just like placing a gravitational "blac...

Abstract

The invention discloses an electromagnetic coil device, which comprises a winding framework and a cylindrical shell. The winding framework is wound with a conductive coil and is arranged inside the cylindrical shell; a permanent magnet iron core is arranged inside an inner hole formed in the winding framework; the winding framework and the cylindrical shell are non-conductive magnets; and the conductive coil is coupled in a positive / reverse switching circuit. The electromagnetic coil device improves magnetic force strength between the magnetic iron core and the electromagnetic coil and the moving stroke of the magnetic iron core and improves the using effect of the electromagnetic coil.

Description

technical field [0001] The invention relates to an electromagnetic conversion device, in particular to an electromagnetic coil device. Background technique [0002] The essence of the electric field and the magnetic field is unified, and the inherent close properties and specious differences between the two are actually similar in essence, and their characteristics have gradually been known and effectively used by people. [0003] In remote control and automatic control technology, the electromagnetic coil as the electromagnetic field function converter, especially the electromagnetic valve coil device, the distribution of magnetic flux when the coil is energized, as well as the gathering and shunting of magnetic flux determine the magnetic action mode and force of the electromagnetic coil. and lowest energy consumption. [0004] In the prior art, the electromagnetic coil adopts the method of coil outer cover magnetic material shell, and the magnetic flux is mainly distribu...
