Abstract

The utility model relates to an iron core winding for a generator, a motor or a transformer, which belongs to the technical field of armature. The utility model aims to provide the iron core winding for the generator, the motor or the transformer, which has a relatively smaller size, a lighter weight and high conversion efficiency. The technical essentials are as follows: the width of a wire duct (11) arranged on an iron core (1) is less than 3mm, and the upper width and the lower width of the whole wire duct are equal; and a plurality of layers of single enameled wire (2) winding coils are arranged in the wire duct from down to up. Because of the plurality of layers of single winding coils are arranged in the narrow wire duct of the iron core, the structure of the iron core winding is compact; and because the electromagnetic wires of the winding coils are closely attached on the slot wall of the wire duct of the iron core, the cooling performance is particularly good, the magnetic circuit of the iron core winding during the conversion processes between mechanical energy and electrical energy as well as between electrical energy is the shortest, the magnetic resistance of the magnetic circuit is the smallest, a lead cutting magnetic line is nearly vertical cutting, and thus the conversion efficiency is particularly high. Compared with the motor or the transformer with equal power, in the iron core winding for the generator, the motor or the transformer has a relatively smaller size, a relatively lighter weight and higher conversion efficiency.

Description

Generator, motor and transformer core winding

Technical field

The utility model relates to a kind of iron core winding that is used for generator, motor and transformer.

Background technology

At present, be used for all offering on the iron core of generator and motor the wire casing that winding coil is installed, the width of its wire casing is general all greater than 3mm, and the line in wire casing under general be again a bunch of many compositions.Both having made is especially little micromachine, though the broadband of the wire casing of offering on its iron core less than 3mm, its line under in wire casing still is a bunch.Because winding slot of core is big, useful flux is little; And bunch radiating effect in wire casing is poor, and it is cross-laminated mutually, cause the internal resistance of coil to increase, cause copper cash and silicon steel sheet utilance to reduce, cutting magnetic line efficient reduces, cause the winding coil power consumption many, easily heating, thus reduced the mechanical energy of generator and motor and the conversion efficiency between electric energy and electric energy and the electric energy.Therefore, the generator of this structure and motor winding volume are big, Heavy Weight, consumable material are many, and efficient is low.The iron core that is used for transformer is not at present then offered wire casing, its electromagnetic wire all be concentrate turn to coil after, be placed on the iron core periphery again, thus have equally that radiating effect is poor, problem such as the internal resistance increase of coil, conversion efficiency are low.

The utility model content

The purpose of this utility model is intended to overcome the problem that above-mentioned prior art exists, and provides that a kind of relative volume reduces, weight saving, good heat dissipation effect, generator, motor and transformer core winding that conversion efficiency is high.

Its technical scheme is: a kind of generator, motor and transformer core winding, comprise iron core and enamelled wire coil windings, the wire casing of offering on the iron core is the narrow groove of width less than 3mm, it is characterized in that: the upper and lower width of described wire casing equates, includes single several layers enamelled wire coil windings in the wire casing from bottom to top in.

The above-mentioned single several layers of enamelled wire of including in the wire casing all are close to the iron core cell wall.

Be provided with the insulating material of thin layer between the above-mentioned both sides of including single several layers of enamelled wire in the wire casing and wire casing in.

Compare with existing iron core winding, its technique effect is: include single several layers enamelled wire coil windings in owing to adopt in the narrow wire casing of iron core, both made its compact conformation, make the enamelled wire of coil windings be close to the cell wall of winding slot of core again, it is good especially to make it heat dispersion, more makes its magnetic circuit in the transfer process of mechanical energy and electric energy and electric energy and electric energy the shortest, magnetic circuit magnetic resistance minimum, the cutting of lead cutting magnetic line near normal, therefore, conversion efficiency is high especially.In addition, because enamelled wire adopts single layering to place, in the iron core of equal volume, it is the highest that the enamelled wire of placement and volume all can reach, thereby reduced the consumption of iron and copper effectively; Compare with motor or transformer with constant power, adopt iron core winding of the present invention made motor or transformer, its volume is little relatively, and it is light that weight is wanted relatively, and conversion efficiency is higher.

Embodiment

As shown in Figure 1, the iron core winding of generator, motor and transformer comprises iron core and enamelled wire coil windings.The wire casing of offering on the iron core 1 11 is the narrow groove of width less than 3mm, and the upper and lower width of wire casing equates, includes single several layers enamelled wire 2 coil windings in the wire casing from bottom to top in.The single several layers of enamelled wire of including in the wire casing all are close to the iron core cell wall.Include the insulating material 3 that is provided with thin layer between the both sides of single several layers of enamelled wire in the wire casing and wire casing in.

The iron core winding that is used for transformer, can in the wire casing of iron core 1, include winding coil in after, on its end face, place strip iron core 4, make it to constitute the magnetic circuit (see figure 2) of sealing; Also can be with two identical iron cores 1, in wire casing separately, include winding coil in respectively after, tooth is relative with tooth, groove is relative with groove, makes it to constitute the magnetic circuit of sealing.
