The direct current machine of tape insulation shelf structure
Technical field
The present invention relates to a kind of direct current machine of tape insulation shelf structure, specifically is the winding structure of the suitable stator core coiling of direct current machine.
Background technology
The insulating frame structure of the direct current machine that uses does not at present have the insulating frame fixed structure, and insulation system integral body is placed in the motor case; Crossed beam trunking also all is placed on motor case inside; Significantly reduce the motor slot area like this, cause copper factor to increase, reduce electric machine winding speed; And insulating frame does not have the Hall installation position yet, and the Hall installation place flushes, and Hall must increase the length of permanent magnet in order effectively to respond to tile like this, has increased cost, and owing to insulating frame stops, very inconvenient in the time of inspection.
Summary of the invention
[0003] the objective of the invention is to consider above-mentionedly deposit the problem that insulating frame exists and a kind of direct current machine of tape insulation shelf structure is provided; The insulating frame that not only makes of the present invention has fixed structure preferably; Improve the casing concentricity, and can effectively reduce copper factor, improve threading speed; The deperm use amount of material is convenient to the installation of Hall and the detection of signal.
Technical scheme of the present invention is: a kind of direct current machine of tape insulation shelf structure; Comprise upper casing, control board, last insulating frame, stator core, following insulating frame, rotor and lower casing; The wherein said insulating frame of going up is inserted on the stator core with following insulating frame, and said upper casing cooperates formation installation and control plate, the last cavity of insulating frame, stator core, following insulating frame and rotor with lower casing; It is characterized in that said control board is stuck on the insulating frame; Be provided with groove, line-dividing, Hall installation position, annular crossed beam trunking and fixed bit on the insulating frame on said; On said stator core, be provided with installing hole, said fixed bit embeds in the installing hole of stator core, and said annular crossed beam trunking is located at the insulating frame edge; The base of said upper casing is pressed on the annular crossed beam trunking, and the convex of upper casing embeds in the groove of going up insulating frame.
The said insulating frame of going up is provided with the fixed bit more than two, and said fixed bit is located at the peripheral of annular crossed beam trunking and axially outer outstanding, and fixed bit and groove pairing occur.
Saidly go up the Hall that insulating frame is provided with more than three and put the dress position, said Hall is put the dress position and can continuous distribution also can evenly be distributed, and it can be that through hole also can half through hole that Hall is put the dress position.
Be provided with the draw-in groove more than two at the edge of said control board, be provided with the control board fixed bit more than two on the insulating frame on said, said control board fixed bit is fastened in the draw-in groove control board is stuck on the insulating frame.
The present invention's advantage compared with prior art is: improved insulating frame concentricity is installed; Solve hall position and respond to bad problem; Because annular crossed beam trunking moves to the edge of insulating frame from original interior, has increased the motor slot area, can effectively reduce copper factor; Improve threading speed, improve whole motor performance.

Embodiment
To combine accompanying drawing and embodiment that the present invention is described in further detail below.
Shown in Fig. 1 to 9; A kind of direct current machine of tape insulation shelf structure; Comprise upper casing 1, control board 2, last insulating frame 3, stator core 4, following insulating frame 5, rotor 6 and lower casing 7; The wherein said insulating frame 3 of going up is inserted on the stator core 4 with following insulating frame 5, and said upper casing 1 cooperates formation installation and control plate 2, the last cavity of insulating frame 3, stator core 4, following insulating frame 5 and rotor 6 with lower casing 7; Characteristics of the present invention are that said control board 2 is stuck on the insulating frame 3; Be provided with groove 31, line-dividing 32, Hall installation position 34, annular crossed beam trunking 35 and fixed bit 36 on the insulating frame 3 on said; On said stator core 4, be provided with installing hole 41; Said fixed bit 36 embeds in the installing hole 41 of stator core 4, and stator core 4 and last insulating frame 3 are fixed; Said annular crossed beam trunking 35 is located at insulating frame 3 edges, and the base 11 of said upper casing 1 is pressed on the annular crossed beam trunking 35; The convex 12 of upper casing 1 embeds in the groove 31 of going up insulating frame 3, and upper casing 1 and last insulating frame 3 are fixed.
The said insulating frame 3 of going up is provided with the fixed bit 36 more than two, and said fixed bit 36 is located at the peripheral of annular crossed beam trunking 35 and axially outer outstanding, and 31 pairings occur fixed bit 36 with groove.In the present embodiment, on last insulating frame 3, be provided with four fixed bits 36 and four grooves 31, fixed bit 36 and groove 31 concentrics also can be provided with the quantity of fixed bit 36 and groove 31 according to actual needs.
Saidly go up the Hall that insulating frame 3 is provided with more than three and put dress position 34, said Hall is put dress position 34 and can continuous distribution also can evenly be distributed, and it can be that through hole also can half through hole that Hall is put dress position 34.In the present embodiment, on last insulating frame 3, be provided with 12 Halls and put dress position 34, the quantity that Hall is put dress position 34 also can be set according to actual needs.
Be provided with the draw-in groove 21 more than two at the edge of said control board 2, be provided with the control board fixed bit 33 more than two on the insulating frame 3 on said, said control board fixed bit 33 is fastened in the draw-in groove 21 control board 2 is stuck on the insulating frame 3.In the present embodiment, be provided with four draw-in grooves 21, on last insulating frame 3, be provided with four control board fixed bits 33, the quantity of draw-in groove 21 and control board fixed bit 33 also can be set according to actual needs at the edge of control board 2.
