Description

Technical Field

[0001] This utility model relates to the field of stator frame technology, specifically a motor stator insulation frame assembly. Background Technology

[0002] The stator of a motor is an important component of motors such as generators and starters. It consists of three parts: the stator core, the stator windings, and the frame. The main function of the stator is to generate a rotating magnetic field, while the main function of the rotor is to be cut by magnetic lines of force in the rotating magnetic field to generate current. Insulated motors mainly consist of a stator and a rotor. The stator is generally insulated using an insulating frame, which is an injection-molded part with a wire-passing structure designed and installed at the end of the stator. Insulating paper is placed in the slots of the core to insulate the core and the coils.

[0003] An existing patent application (application number 202222272444.3) describes an insulating frame for a motor stator assembly, including a frame body. This frame offers good insulation and solves the problem that, during use, the insulating frame's paper-clamping structure is prone to damaging the insulating groove paper, and when the insulating groove paper is wrinkled or damaged, it easily affects the insulation between the core and the coil. However, the inner frame body is fixed as a whole, making it difficult to accommodate stator frames of different thicknesses for winding applications. Utility Model Content

[0006] Furthermore, the first limiting groove is configured as an annular groove, and the inner support is configured as an annular support.

[0007] Furthermore, a limiting sliding hole is provided on the side wall of the upper frame on one side of the first limiting groove, and the positioning rod is slidably disposed in the limiting sliding hole.

[0008] Furthermore, the positioning rods and limiting nuts are arranged in a circular array in multiple sets, and the inner side of the limiting nuts is also provided with anti-slip pads.

[0009] Furthermore, a second limiting groove is provided inside one end of the upper limit plate, and one end of the support rod is slidably inserted into the second limiting groove.

This allows the spacing between the upper and lower frames to be adjusted by adjusting the depth of the inner bracket inserted into the upper frame, thereby meeting the requirements for winding stator skeletons of different thicknesses. Moreover, the structure is simple and the adjustment is convenient.

[0013] 2. In this utility model, the upper limit end plate and the lower limit end plate are connected by a support rod.
