Description

Technical Field

[0001] The utility model relates to the technical field of motors, in particular to a permanent magnet synchronous servo motor winding shaping die. Background Art

[0002] In recent years, with the development of permanent magnet materials and the progress of power electronic components, not only has the pace of research and development of permanent magnet synchronous servo motors been accelerated, but also its application areas have been improved. Because it not only has the characteristics of high power density and high efficiency, but also can meet the requirements of energy saving and miniaturization. In order to shape and organize the stator winding of the permanent magnet synchronous servo motor after the wire is embedded, a rubber hammer will be used to knock the inner circle of the stator winding to make it regular, such as Figure 1 As shown, the inner circle 02 of the stator winding is a conical surface. After the copper wire is embedded in the stator winding, the winding at the end is irregular. In order to make the inner circle of the end of the stator winding 01 uniform and regular, a rubber hammer is used to knock the inner circle of the stator end for shaping, which is inefficient and has poor consistency.

[0003] Based on the above defects and shortcomings, it is necessary to improve the existing technology and design a permanent magnet synchronous servo motor winding shaping die. Utility Model Content

The limiting step can be stuck on the end face of the inner hole of the stator iron wire of the stator winding, so as to limit the position of the stator shaping mold and prevent it from damaging the stator winding due to excessive shaping.

[0006] Preferably, the limiting step includes a first step larger than the inner diameter of the stator iron wire and a second step smaller than the inner diameter of the stator core.

[0007] Preferably, the first step shaft diameter ΦD1 is 1-2 mm larger than the inner diameter of the stator iron wire, and the second step shaft diameter ΦD2 is 0.5-1 mm smaller than the inner diameter of the stator core.

The screw passes through the locking through hole and is locked to the round steel. The arrangement of the round steel is convenient for the hand to grasp with a manipulator, and it is convenient to take and place the stator shaping mold.

[0009] Preferably, a threaded mounting hole cooperating with a screw is provided on the lower end surface of the round steel.

[0010] Compared with the prior art, the beneficial effects of the utility model are:
