Problems solved by technology
[0003] The purpose of this invention is to provide a new stator end wiring process to solve the problem of stator wiring in high-power motors. The lead wires at the end of the stator winding can be controlled within the outer diameter of the stator. The method is to fix the lead wires at the ends Axial
[0005] Beneficial effects of the present invention: This process solves the problem that the company's large motor is changed to external press-fitting, because the winding lead wires exceed the outer circle of the stator, and provides more possibilities for the product structure design of the large motor

Embodiment Construction
[0013] like figure 1 , Figure 2-5 As shown, the patent of the present invention is realized in such a way that the stator winding end connection tooling 12 is fixed on the stator winding terminal 11, the winding lead wire is put on a sleeve, and along the six fixed hooks of the stator winding end connection tooling 12 Axial positioning, the lead wires are arranged in three layers in the axial direction of the stator winding terminal 11. The first layer of stator winding leads 13 refer to image 3 Wiring along the fixing hooks, and so on to fix the lead-out wires 14 of the second layer stator winding and the lead-out wires 15 of the third layer stator winding, and tie the three-layer lead wires tightly with Polyester tape to form an "end hoop". "8" character reference Image 6 , tighten the "end hoop" in the axial direction of the stator winding terminal 11, and shape it in place, and finally disassemble the stator winding end connection tooling 12.

The invention discloses a novel stator end wiring process. A stator winding end wiring tool is fixed at the wiring end of a stator winding; stator winding outgoing lines are sleeved with sleeve pipes, and are axially positioned along six or eight fixed hooks of the stator winding end wiring tool; the stator winding outgoing lines are placed in the axial direction of the end in three layers; the stator winding outgoing lines are bundled tightly by polyester fiber bands to form an ''end clamping ring''; binding tapes are bundled in an 8 shape; the ''end clamping ring'' is tightly bundled in the axial direction of the wiring end of the stator winding, and shaped in position; and finally, the wiring tool at the end of the stator winding is dismantled. The novel stator end wiring process has the beneficial effects that the problem that the winding outgoing lines exceed the outer circle of the stator due to high quantity of the winding outgoing lines existing in an improved process of outer press-mounting for a large motor is solved; and more probabilities are provided to the structural design of large-motor products.
Description
technical field [0001] The invention relates to a high-power external pressure-mounted stator wiring process, in particular to a novel stator end wiring process. Background technique [0002] For the company’s high-power motors above 550kw, the internal press-fitting process is used, and the manufacturing cycle is long. If the external press-fitting process is changed, a very critical technical problem needs to be solved, which is the wiring problem at the end of the stator winding. The traditional stator wiring process is to The lead wires are bound on the outer diameter of the stator end. Due to the thick and many lead wires of the stator winding of a high-power motor, the end of the winding will be close to or even exceed the outer circle of the stator. Considering that the stator will touch the ribs of the frame when it is pressed into the frame , so the traditional stator wiring process is an impediment to high-power conversion to external press-fitting.
