Abstract
The invention discloses a winding insulating air flue structure at the upper end of a magnetic suspension motor stator. The winding insulating air flue structure comprises a stator core, a copper wire and a circular insulating plate formed by combining four sector upper insulating end plates, wherein the insulating plate is arranged at the upper end of the stator core; the copper wire is wound on the stator core and the insulating plate, and is used for fixing the insulating plate on the stator core; a plurality of connecting rids are uniformly distributed in the peripheral direction of each upper insulating end plate, a through hole is formed between every two adjacent connecting rids, and the through holes are communicated with winding grooves in the axis direction of the stator core; each connecting rib is fixedly connected with a partition plate, and an insulating air flue is formed between every two adjacent partition plates. The winding insulating air flue structure is simple in structure, and due to the fact that the partition plates are arranged on the upper insulating end plates, insulation between phases is effectively protected; the insulating air flues formed between the adjacent partition plates on the upper insulating end plates can reduce calorific value of the motor stator more quickly and more uniformly, so that the motor stator is greatly protected, and the service life of the stator is prolonged.
Description
Technical field：
The present invention relates to a kind of coiling insulation air channel structure of magnetic suspension motor stator upper end.
Background technology：
It is the distance between control magnetcisuspension floating centrifugal motor stator both ends in existing magnetcisuspension floating centrifugal motor,
Using the wound winding mode of the back of the body, the insulation of motor stator winding fully relies on insulating paper and is spaced apart two phase place is motor stator,
But the factors such as motor meeting in running is constantly vibrated, heating, make the insulation damages of stator winding, so insulating paper is deposited
In certain potential safety hazard, radiate also uneven.
Therefore, it is necessory to be improved the deficiency to solve prior art to prior art.
The content of the invention：
The present invention is to provide a kind of magnetic suspension motor stator upper end to solve the problems, such as above-mentioned prior art
Coiling insulation air channel structure.
The technical solution adopted in the present invention has：A kind of coiling insulation air channel structure of magnetic suspension motor stator upper end,
The toroidal insulation board for being formed is combined including stator core, copper cash and by insulating end plate on four pieces of fan shapes, the insulation board sets
In the upper end of stator core, copper cash is set around on stator core and insulation board, and insulation board is fixed on stator core；It is described
Be evenly equipped with the circumferencial direction of upper insulating end plate between some dowels, and two adjacent dowels and be provided with through hole, the through hole with
Winding slot on stator core axis direction connects；
It is fixedly connected with the dowel between dividing plate, and two adjacent dividing plates and is formed with insulation air channel.
Further, the dowel is arranged along the radial direction of upper insulating end plate.
Further, the center of the insulation board is provided with through hole, and the through hole connects with the axis hole on stator core.
The present invention has the advantages that：Present configuration is simple, because upper insulating end plate is provided with dividing plate, effectively
Protect phase insulation；The insulation air channel formed between adjacent separator on upper insulating end plate, reduction that can faster, evenly is electric
The caloric value of machine stator, protects motor stator significantly, extends the service life of stator.
Description of the drawings：
Fig. 1 is the structure chart of the present invention.
Fig. 2 is the structure chart of upper insulating end plate in the present invention.
Specific embodiment：
Below in conjunction with the accompanying drawings the present invention is further illustrated.
As depicted in figs. 1 and 2, the coiling insulation air channel structure of a kind of magnetic suspension motor stator upper end of the invention, including

The upper end of stator core 2, copper cash is set around on stator core 2 and insulation board 1, and insulation board 1 is fixed on stator core 2.
Some dowels 11, and the dowel 11 are evenly equipped with the circumferencial direction of upper insulating end plate 10 along upper insulating end
The radial direction of plate 10 is arranged, and between two adjacent dowels 11 through hole 12 is provided with, the through hole 12 be located at the axis of stator core 2
Winding slot 21 on direction connects.
It is fixedly connected with dowel 11 between dividing plate 13, and two adjacent dividing plates 13 and is formed with insulation air channel 14, should
Connect with through hole 12, the caloric value of reduction motor stator that can faster, evenly protects motor stator significantly, extends
The service life of stator.
Through hole 15 is provided with the center of insulation board 1, the through hole 15 connects with the axis hole on stator core 2.
The above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, some improvement can also be made under the premise without departing from the principles of the invention, these improvement also should be regarded as the present invention's
Protection domain.
