specific Embodiment approach

[0033] like Figure 4 to Figure 7 As shown, this embodiment proposes a preferred insulating skeleton, which includes an annular outer wall 1 and an inner wall 2, and a plurality of winding parts 3 connected between the outer wall 1 and the inner wall 2 for winding stator windings, wherein , the inner wall 2 is composed of a plurality of inner baffles 21 distributed at intervals, the number of inner baffles 21 and the winding parts 3 are the same, and the two are distributed in one-to-one correspondence, two adjacent winding parts 3, and two winding parts are connected The outer wall 1 of 3 and the two inner baffles 21 respectively connecting the two winding parts 3 jointly form an insulating skeleton groove 6, which is a groove with the opening facing inward and the opening size gradually decreasing from the outside to the inside, which can It is convenient for the insulating frame to be assembled in the iron core slot of the stator iron core.

Abstract

The invention discloses an insulating frame, and relates to the technical field of motors. The insulating frame includes an outer wall and an inner wall that surround each other. The outer wall and the inner wall are connected through multiple coiling parts. The inner wall is formed by multiple inner baffle plates arranged at intervals. The number of the inner baffle plates is equal to that of the coiling parts, and the inner baffle plates correspond to the coiling parts one by one. The bottom on the inner side of each of two ends of each inner baffle plate is equipped with a groove paper buckle, a groove paper clamping groove is disposed between each groove paper buckle and one corresponding inner baffle plate, and the bottom of each of the two ends of each inner baffle plate is also equipped with a groove structure that is communicated with the corresponding groove paper clamping groove. The invention also discloses a motor stator and a motor including the insulating frame The bottom walls on the two ends of each inner baffle plate are additionally provided with the groove structures that are communicated with the groove paper clamping grooves to enable the space of the groove paper clamping grooves to be increased, so groove paper will not be drawn into an iron core along with coiling pins during coiling. Therefore, the cooperation range between the groove paper and the insulating frame is increased, the tighter contact performance is exhibited, hidden troubles of causing the groove paper to be drawn into the iron core after coiling are effectively reduced, and groove winding is less likely to occur.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to an insulating frame in the motor, a motor stator with the insulating frame and a motor with the motor stator. Background technique [0002] The insulated motor is mainly composed of a stator and a rotor, and the motor stator is generally insulated by an insulating frame. The insulating skeleton is an injection molded part that is arranged at the end of the motor stator and has a wire-passing structure design. The traditional insulating frame cannot play the role of slot insulation, therefore, it is necessary to place insulating slot paper in the iron core slot to insulate the iron core slot and the wire package. After the insulating slot paper is installed in the iron core slot of the motor stator, the insulating slot paper is not easily fixed by the insulating frame. If the insulation slot paper is loose towards the iron core slot of the motor stator, the wire nozzle may be hun...
