Description

Technical Field

[0001] The invention relates to the technical field of motor stator end ring fixing, and in particular to a motor stator end ring fixing method. Background Art

[0002] The motor stator assembly consists of an iron core, windings, end rings, and end ring support frames. The end rings are used to connect the windings in parallel to output the motor current. As the motor capacity increases, the end ring specifications also increase. The end ring support frame plays an important role in fixing the end rings to ensure that they are firmly and reliably positioned.

[0003] At present, the motor stator end ring is fixed by only a single screw or axial bracket, or a combination of the two. The single screw fixation lacks axial support, the single axial bracket lacks radial support, and the combined support force in two directions is insufficient. As the number of end rings increases and the specifications become larger, these methods will not be enough to support the heavy end rings and the fixation will no longer be firm. Summary of the invention

[0004] In order to solve the above problems, the present invention discloses a method for fixing the stator end ring of a motor, which can withstand the end ring pressure of greater weight in radial and axial directions, and has accurate positioning, firm and reliable support and fixing.

[0005] The specific plan is as follows: A method for fixing a motor stator end ring, characterized in that it comprises the following steps: S1. Fix the end ring bracket on the upper end surface of the stator core; S2. Alternately stack the spacers and end rings on the end ring bracket; S3. Use binding tape to tie the end ring, spacer and end ring bracket together to achieve radial and axial bidirectional fixation of the end ring.

[0006] Furthermore, the end ring bracket includes a vertical rod, a horizontal rod and a base, the lower end of the vertical rod is fixed on the base, and one end of the horizontal rod is fixed to the side of the vertical rod.

[0007] Furthermore, two symmetrically arranged mounting holes are provided on the base, and the mounting holes are used to fix the end ring bracket to the upper end surface of the stator core through washers and bolts.

[0008] Furthermore, the end ring brackets are evenly arranged on the upper end surface of the stator core along the circumferential direction.

[0009] The beneficial effects of the present invention are that the present invention can withstand end ring pressure of greater weight in radial and axial directions, and has accurate positioning, firm and reliable support and fixation; it can not only be used for fixing motor stator end rings, but also can be applied to other fields where axial and radial fixation are required.
