Abstract
The utility model discloses a copper aluminium combines excitation coil, excitation coil is formed by the wire coiling that copper core line and aluminium core line were plugged into and are formed. Because the aluminum core wire is adopted by the excitation coil of the utility model to replace the outer layer wire of the existing coil, the material cost of the excitation coil is reduced; under the condition of the same resistance, the volume of the copper-aluminum combined excitation coil is larger, and the heat dissipation space of the coil is enlarged, so that the heat dissipation effect is improved; the magnetic strength of excitation coil mainly concentrates on being close to the iron core lean on the inlayer coil, the utility model discloses an excitation coil lean on inlayer coil still copper core line, still keep the magnetic field intensity of current coil.
Description
Technical Field
The utility model relates to an electro-magnet technical field especially indicates excitation coil in the electro-magnet.
Background
In the magnetic separation industry, the magnetic field requires electromagnets to provide the working magnetic field. The coil of this kind of electro-magnet at present adopts copper core enameled wire to wind mostly, and is with high costs, and the radiating effect is not good moreover, still needs the space that promotes.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to provide a reduce the cost, promote the excitation coil of heat dispersion.
The technical scheme adopted for solving the technical problems is as follows: a copper-aluminum combines excitation coil, its characterized in that: the magnet exciting coil is formed by winding a wire formed by connecting a copper core wire and an aluminum core wire.
On the basis, the inner layer wire of the excitation coil is a copper core wire, and the outer layer wire of the excitation coil is an aluminum core wire.
Adopt the utility model discloses the beneficial effect who brings: because the aluminum core wire is adopted by the excitation coil of the utility model to replace the outer layer wire of the existing coil, the material cost of the excitation coil is reduced; under the condition of the same resistance, the volume of the copper-aluminum combined excitation coil is larger, and the heat dissipation space of the coil is enlarged, so that the heat dissipation effect is improved; the magnetic strength of excitation coil mainly concentrates on being close to the iron core lean on the inlayer coil, the utility model discloses an excitation coil lean on inlayer coil still copper core line, still keep the magnetic field intensity of current coil.
Drawings
Fig. 1 is a schematic structural diagram of the copper-aluminum combined excitation coil of the present invention.
Detailed Description
As shown in fig. 1, the field coil is formed by winding a wire formed by connecting a copper core wire 1 and an aluminum core wire 2. The excitation coil is close to the inlayer wire and is copper core 1, leans on the outer layer wire to be aluminium core 2.
The utility model adopts the aluminum core wire to replace the outer layer wire of the existing coil, thereby reducing the material cost of the excitation coil; under the condition of the same resistance, the volume of the copper-aluminum combined excitation coil is larger, and the heat dissipation space of the coil is enlarged, so that the heat dissipation effect is improved; the magnetic strength of excitation coil mainly concentrates on being close to the iron core lean on the inlayer coil, the utility model discloses an excitation coil lean on inlayer coil still copper core line, still keep the magnetic field intensity of current coil.
Claims (2)
