Embodiment 1

[0042] Such as Figures 1 to 9 Shown is the motor skeleton proposed in this embodiment, and the motor skeleton is set on the iron core by integral injection molding. The skeleton includes an insulating layer, and the insulating layer is coated on the outer surface of the iron core with equal thickness along the outline of the iron core. The insulating layer in this embodiment reduces the thickness of the original insulating layer to A reduction of more than 1 / 3 can improve the utilization rate of the iron core winding slot, increase the maximum slot full rate and material utilization rate, and improve the performance of the motor. Using injection molding reduces the difficulty of mold manufacturing, which can greatly improve production efficiency and yield. The skeleton does not need to be reassembled manually, which saves labor and management costs, and avoids the possibility of skeleton damage and deformation caused by the manual nesting process. In addition, direct injecti...

Embodiment 2

[0049] This embodiment discloses a motor, which includes an iron core, and the motor skeleton as described in Embodiment 1 is arranged outside the iron core. Since the motor is provided with the above-mentioned motor frame, the motor has higher reliability and better economy, and is suitable for large-scale popularization and use.

Abstract

The invention discloses a motor framework and a motor. The motor framework is arranged on the outer portion of an iron core in an integral injection molding mode. The framework comprises an insulating layer, and the insulating layer covers the outer surface of the iron core in an equal-thickness mode along the contour of the iron core. According to the motor framework, the framework die production and manufacturing difficulty is lowered, and the production efficiency and yield can be improved greatly. Compared with an original framework installing mode, the framework does not need to be manually assembled once again, the labor cost and management cost are reduced, and the risk of damage and deformation of the framework in the manual nesting process is avoided. Moreover, the adhering tightness of the iron core and the framework is guaranteed to the largest extent through direct injection molding, harmful gaps between the iron core and the framework are avoided, reluctance and flux leakage can be effectively reduced, the winding usage amount can be saved, and the iron core utilization rate is maximized.

Description

technical field [0001] The invention relates to the field of motors, and more specifically discloses a motor frame and a motor. Background technique [0002] A motor in the prior art is usually composed of a stator, a rotor, and a casing, and the stator mainly includes a stator core, a skeleton (ie, an insulating structure) and a stator winding. The existing frame generally adopts the upper and lower nesting structure. Due to the limitation of the mechanical strength of the supporting part, the insulation part of the frame groove cannot be made very thin, and the overall structure is unreasonable, resulting in a low slot full rate and an excessive amount of copper, which reduces the use of the motor. performance. [0003] The coordination between the frame and the stator core is complex, and manual nesting is required during installation, resulting in low installation efficiency and a high defect rate. Since the skeleton has the function of constraining the wire package, t...
