Embodiment 1

[0024] Combined reference Figure 1~3 As shown, the stator winding end insulating frame 1 provided by the first embodiment of the present invention includes an insulating frame body 11 sleeved on the axial end 21 of the stator winding 2 along the motor axis. The insulating frame body 11 includes an insulating frame body 11 along the motor axis. The annular panel 111 located 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 in the radial direction of the motor, and the inner panel 112 bent along the outer edge of the annular panel 111. The outer panel 113 located on the outer side of the stator winding 2 in the radial direction of the motor is provided with a number of inner positioning protrusions 12 on the inner panel 112 in the direction away from the outer panel 113 in the radial direction of the motor; and / or, the outer panel 113 extends along the motor A plurality of outer pos...

Embodiment 2

[0041] Such as Figure 4 As shown, the main difference between the stator winding end insulation frame 1, the plastic-encapsulated stator assembly, and the plastic-encapsulated motor provided by this embodiment is that the stator winding end insulation frame 1 in this embodiment is not equipped with a PG board. The frame 15, the protector mounting frame 16, the lead wire fixing frame 17, and the terminal box 18, that is, the stator winding end insulation frame 1 in this embodiment is not used for the PG plate member 5, the temperature protector, and the PG plate lead wire 6 and the stator winding lead wire for installation and positioning. However, since the stator winding end insulation frame 1 in this embodiment is also provided with inner positioning protrusions 12 and / or outer positioning protrusions 13, the stator winding end insulation frame 1 of this embodiment is used for the stator winding 2 When the axial end 21 is insulated, it can also prevent the stator winding end...

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 insulation frame, a plastic-encapsulated stator assembly with the stator winding end insulation frame, and a plastic-encapsulated motor with the plastic-encapsulated 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 motor axis. In traditional technology, the stator winding axial ends are fixed and insulated. The method is as follows: first use tape and cotton yarn to bind and fix the axial ends of the stator windings, and then perform the insulation varnish treatment. This treatment method has complex procedures, cumbersome operations, and long production cycles in specific applications. The defects of automated production operations and high labor costs. [0003] In order to overcome the above-mentioned shortcomings of the trad...
