Embodiment 1

[0024] combined reference Figure 1~3 As shown, the stator winding end insulating frame 1 provided by Embodiment 1 of the present invention includes an insulating frame body 11 sleeved on the axial end 21 of the stator winding 2 along the motor axial direction, and the insulating frame body 11 includes a The annular panel 111 on one side of the stator winding 2, the inner panel 112 bent along the inner edge of the annular panel 111 and located inside the stator winding 2 along the radial direction of the motor, and the inner panel 112 bent along the outer edge of the annular panel 111 and The outer panel 113 located outside the stator winding 2 in the radial direction of the motor, the inner panel 112 is provided with several inner positioning protrusions 12 along the motor radial direction away from the outer panel 113; and / or, the outer panel 113 is located along the motor Several outer positioning protrusions 13 protrude radially away from the inner panel 112 . The stator ...

Embodiment 2

[0041] Such as Figure 4 As shown, the stator winding end insulating frame 1, the plastic-encapsulated stator assembly and the plastic-encapsulated motor provided in this embodiment are mainly different from the first embodiment in that there is no PG board installed on the stator winding end insulating frame 1 in this embodiment. Frame 15, protector mounting frame 16, lead wire fixing frame 17 and terminal box 18, that is, the stator winding end insulation frame 1 in this embodiment is not used for PG plate member 5, temperature protector, PG plate lead wire 6 and stator winding lead wires for installation and positioning. However, since the insulating frame 1 at the end of the stator winding in this embodiment is also provided with the inner positioning protrusion 12 and / or the outer positioning protrusion 13, the stator winding end insulating frame 1 of the present embodiment is used for the stator winding 2 When the axial end 21 of the stator winding is insulated, it can ...

Abstract

The invention is suitable for the field of motors, and discloses a stator winding end insulation frame, a plastic-packaging stator assembly, and a plastic-packaging motor. The insulation frame comprises an insulation frame body which is disposed at an axial end part of a stator winding along the axial direction of a motor in a sleeve manner. The insulation frame body comprises an annular panel, an inner side panel, and an outer side panel, wherein the inner side panel is provided with a plurality of inner side positioning convex blocks in a convex manner, and/or the outer side panel is provided with a plurality of outer side positioning convex blocks in a convex manner. According to the invention, the inner side positioning convex blocks and/or the outer side positioning convex blocks can abut against a plastic-packaging mold radially in a plastic-packaging process, thereby preventing the insulation frame from deflecting radially because of the injection molding pressure of plastic-packaging materials, preventing a large part of the insulation frame from being exposed after plastic packaging, further improving the bonding intensity of the plastic-packaging housing with the insulation frame, improving the beauty of a product, and finally improving the qualified rate of products.

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...
