Abstract

The utility model discloses a stator component of a traction motor, which comprises an outer shell, an iron core made of a silicon-steel plate and a stator coil group coiled on the iron core, wherein the stator coil group is made of flat copper enameled wires which are coiled. The stator component has the advantages that the coil group of the stator component of the traction motor is coiled by the flat copper enameled wires, thereby the structure is more compact than coil groups made of round copper enameled wires, the volume of the coil group coiled by the flat copper wires is smaller than the traditional coil groups with the same number of turns, the cross area of the flat copper enameled wires is big, the mechanical strength and the rigidity are stronger, and the bearing capability is higher.

Description

The stator module of traction electric machine

Technical field

The utility model relates to the stator module of a kind of stator of motor, particularly a kind of traction electric machine.

Background technology

The operation principle of traction motor is identical with general DC motor, but special condition of work is arranged, bulk is subjected to the restriction of gauge and driving wheel diameter, when closing track switch by rail gap, locomotive operation to bear sizable impact shock, can produce strong twisting vibration on the armature during size poor gear engagement, in adverse circumstances, use rain, the easy intrusion of snow dust and sand etc.Therefore traction motor also has many requirements on design and structure, make compact conformation as making full use of the internal body space, adopt higher insulating material and arrive this material, parts need have higher mechanical strength and rigidity, whole motor must have good ventilation and heat condition and dust and moisture ability, take special measure with the commutation condition of dealing with the comparison difficulty to reduce spark under the carbon brush etc.At present, the coil groups of the stator module of existing traction electric machine all is to form with round copper enamelled wire coiling, can leave a lot of slits in the middle of the coil groups, and the volume of coil groups is increased, and does not satisfy the designing requirement of traction locomotive electric machine structure compactness.

Summary of the invention

The purpose of this utility model is at the bulky problem of the coil groups of the stator module of the existing traction electric machine described in the background technology, and a kind of carriage traction electric machine stator module is provided.

The realization the technical solution of the utility model is as follows:

A kind of stator module of traction electric machine, the iron core that it comprises shell, make with silicon steel sheet and be wrapped in sets of stator coils on the iron core, described sets of stator coils is entwined with the flat copper enamelled wire.

Described iron core and sets of stator coils are fixed on the shell of stator module by hex screw and spring leaf.

The beneficial effects of the utility model are that the coil groups of the stator module of traction electric machine forms with the coiling of flat copper enamelled wire, so it is tightr with respect to the coil groups structure that round copper enamelled wire coiling forms, coil groups for same number of turns, the coil groups volume that turns to flat type copper wire is littler, and flat copper enamelled wire sectional area is big, its mechanical strength and rigidity are stronger, and bearing capacity is higher.

Description of drawings

Fig. 1 is a schematic diagram of the present utility model;

Among the figure, 1 is shell, and 2 is iron core, and 3 is sets of stator coils.

Embodiment

With reference to the stator module of a kind of traction electric machine shown in the accompanying drawing 1, the iron core 2 that it comprises shell 1, make with silicon steel sheet and be wrapped in sets of stator coils 3 on the iron core 2, described sets of stator coils 3 usefulness flat copper enamelled wires are entwined.Described iron core 2 and sets of stator coils 3 are fixed on the shell of stator module by immobilising devices such as hex screw and spring leafs.At present, the sets of stator coils 3 of the stator module of existing traction electric machine all is to form with round copper enamelled wire coiling, because it is bigger that circular copper wire and flat copper enamelled wire are compared the space that produces in the winding process, so coil groups of the same number of turns, volume with the coiling of flat copper enamelled wire is littler, more satisfy the application demand of traction electric machine, be more suitable for being applied to traction electric machine.

Claims

1. the stator module of a traction electric machine, the iron core that it comprises shell, make with silicon steel sheet and be wrapped in sets of stator coils on the iron core, it is characterized in that: described sets of stator coils is entwined with the flat copper enamelled wire.

2. the stator module of traction electric machine according to claim 1, it is characterized in that: described iron core and sets of stator coils are fixed on the shell of stator module by hex screw and spring leaf.
