Problems solved by technology

[0002] At present, there are two main wiring structures at the end of the traction motor of a locomotive: 1. The wiring structure of the overlapping connection between the poles. The existing problems are that it is difficult to bind the wiring after the welding of the poles and the impact resistance is poor; 2. Axial double-row collector ring wiring structure, the problem is that the structure needs to sacrifice the performance of the motor to meet its larger axial space requirements, and the greater weight of the wiring reduces its impact resistance

Embodiment 1

[0037] In view of the problems of large axial size and weak motor performance in the current in-line structure of traction motors, it is difficult to obtain the best of both worlds in terms of the axial size of the motor and the performance of the motor. This embodiment proposes an optimized and improved solution to solve the problems existing in the prior art.

[0038] Specifically, such as Figure 1 ~ Figure 3 As shown, this embodiment discloses a new type of traction motor wiring structure, including several confluence rings coaxially arranged on the same plane, and several confluence rings are connected as a whole through several first binding structures arranged along the circumference, and It is fixed by several second binding structures arranged along the circumference; the first binding structure includes a first insulating member 7 arranged between two adjacent collector rings, and a plugging felt is also arranged between the first insulating member 7 and the collecto...

Abstract

The invention relates to the technical field of motors, in particular to a novel traction motor connecting line structure and a binding method. According to the novel traction motor connecting line structure, a plurality of collector rings are arranged on the same plane, and the axial space is reduced; the binding piece and the independently designed insulating piece are used for binding step by step, so that the problem of difficulty in binding is solved, an integrated effect is achieved, the weight of a connecting line is small, the impact resistance is high, and the traction performance is better after the motor works.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a novel traction motor wiring structure and a binding method. Background technique [0002] At present, there are two main wiring structures at the end of the traction motor of a locomotive: 1. The wiring structure of the overlapping connection between the poles. The existing problems are that it is difficult to bind the wiring after the welding of the poles and the impact resistance is poor; 2. The problem with the axial double-row collector ring connection structure is that the structure needs to sacrifice the performance of the motor to meet its larger axial space requirements, and the greater connection weight reduces its impact resistance. [0003] Therefore, there is an urgent need for improvement in the existing wiring structure of the traction motor. The wiring structure of the traction motor should be optimized and improved. On the premise of satisfying the performance of...
