Embodiment Construction

[0019] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0020] It should be noted that when an element is referred to as being “fixed” or “disposed on” another element, it may be directly on the other element or there may be an intervening element at the same time. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present.

[0021] It should also be noted that the orientation terms such as left, right, up, down, top, and bottom in the following examples are only relative concepts or refer to the normal use status of the product, and should not be ...

Abstract

The invention is applicable to the field of motors, and discloses an insulating frame at the end of the stator winding, a plastic-sealed stator assembly and a plastic-sealed motor, wherein the insulating frame at the end of the stator winding includes an insulating frame sleeved on the axial end of the stator winding along the axial direction of the motor Body, the insulating frame body includes an annular panel located on one side of the stator winding along the motor axial direction, an inner panel located inside the stator winding along the motor radial direction, and an outer panel located outside the stator winding along the motor radial direction, the annular panel and / or The inner panel and / or the outer panel are provided with a plurality of injection holes for injecting plastic sealing material to form a plastic sealing positioning column. In the present invention, injection molding holes are provided on the insulating frame at the end of the stator winding so that the plastic sealing material can be injected into the injection hole and form a plastic sealing positioning column, thereby enhancing the bonding strength between the insulating frame at the end of the stator winding and the plastic sealing shell, and improving the stability of the stator. Positioning reliability of the insulation frame at the winding ends and reliability of the insulation at the axial ends of the stator windings.

Description

technical field [0001] The invention belongs to the field of motors, and in particular relates to a stator winding end insulating frame, a plastic-sealed stator assembly with the stator winding end insulation frame and a plastic-sealed motor with the plastic-sealed stator assembly. Background technique [0002] After the stator winding is wound on the stator core, it generally has two axial ends protruding from both ends of the stator core along the axial direction of the motor. In the traditional technology, the fixing and insulation treatment of the axial ends of the stator winding The method is as follows: first use tape and cotton yarn to bind and fix the axial end of the stator winding, and then perform insulating varnish treatment. This treatment method has complex procedures, cumbersome operations, and long production cycles in specific applications. Defects of automated production operations and high labor costs. [0003] In order to overcome the defects of the abov...
