Description
Technical field
The utility model is related to a kind of stator of magneto and the motor using the stator, particularly makes in electric tool
Permanent magnet DC motor stator and the motor using the stator.
Background technology
Electric tool it is actual when using, whole chance has than larger vibrations, for magneto magnets of stator it is viscous
Connecing reliability has comparing requirement high.Existing structure is directly will to be directly bonded in smooth machine after magnets of stator spreading glue
Shell inner surface, because casing surface is too smooth, in the case where glue is filled, glue bonding force on enclosure wall still compares
It is small so that magnet easily situation about releasing occurs under high temperature and the operating mode of vibrations high.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of permanent magnet DC motor stator, the letter of its assembling mode
It is single, the consumption of glue can be reduced, improve holistic cost reduction, reliability.
In order to solve the above technical problems, the utility model provides a kind of permanent magnet DC motor stator, including stator
Shell, the stator cage inner surface has frictional layer；There is glue layer on the frictional layer；Magnet layer is bonded with the glue layer；
The frictional layer of the stator cage inner surface is shape of threads decorative pattern.
The beneficial effect of permanent magnet DC motor stator described in the utility model is：Fill its assembling mode simple, can be with
Reduce the consumption of glue, improve holistic cost reduction, reliability.
Preferably, the decorative pattern is highly 0.06 millimeter to 0.3 millimeter.
Preferably, the decorative pattern is highly 0.2 millimeter.
Preferably, the glue layer is completely covered the frictional layer.
Preferably, the magnet layer is completely covered the glue layer.
The utility model additionally provides a kind of permanent magnet DC motor, including stator cage, and inside stator cage
Magnet layer；The stator cage inner surface has frictional layer；There is glue layer on the frictional layer；Magnet is bonded with the glue layer
Layer；The frictional layer of the stator cage inner surface is shape of threads decorative pattern.
Preferably, the decorative pattern is highly 0.06 millimeter to 0.3 millimeter.
Preferably, the decorative pattern is highly 0.2 millimeter.
Preferably, the glue layer is completely covered the frictional layer.
Preferably, the magnet layer is completely covered the glue layer.
The beneficial effect of permanent magnet DC motor described in the utility model is：Fill its assembling mode simple, can reduce
The consumption of glue, improves holistic cost reduction, reliability.
Brief description of the drawings
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
Fig. 1 is the exploded view of permanent magnet DC motor stator described in the utility model embodiment one.
Description of reference numerals：
1st, stator cage；2nd, glue layer；3rd, magnet layer.
Specific embodiment
Permanent magnet DC motor stator described in the present embodiment, including stator cage, the inner surface of the stator cage 1 have friction
Layer；There is glue layer 2 on the frictional layer；Magnet layer 3 is bonded with the glue layer 2.The friction of the inner surface of the stator cage 1
Layer is shape of threads decorative pattern.The decorative pattern is highly 0.1 millimeter -0.3 millimeter.It is 0.2 millimeter that the decorative pattern is highly optimal.It is described
Glue layer 2 is completely covered the frictional layer.The magnet layer 3 is completely covered the glue layer 2.Permanent magnetism described in the utility model
DC motor stator assembling mode is simple, can reduce the consumption of glue, improves holistic cost reduction, reliability.
The utility model is made the shape of shape of threads by stator inner wall by processing, is easy to the glue of magnet in bonding process
In the middle thread groove for more easily penetrating into stator interior, the contact area of glue and stator cage 1 is increased, increase glue is consolidated
Release force after change.Simultaneously as the helicitic texture of stator inner wall, has when in the axial direction of magnet and radially applying thrust
One resistance, the reliability that can equally lift magnet bonding and the consumption for effectively reducing glue.It is of the present invention forever
Magnetic DC motor stator, assembling mode is simple, and without large scale equipment, still product quality significantly improves investment of production less,
The consumption of glue is reduced simultaneously, reduces holistic cost.Except the permanent magnet DC motor stator uses foregoing technical scheme
Outward, other parts can be realized using known form, be will not be repeated here.
The utility model additionally provides a kind of permanent magnet DC motor, including stator cage 1, and inside stator cage 1
Magnet layer 3；The inner surface of the stator cage 1 has frictional layer；There is glue layer 2 on the frictional layer；It is bonded on the glue layer 2
There is magnet layer 3；The frictional layer of the inner surface of the stator cage 1 is shape of threads decorative pattern.The decorative pattern is highly 0.06 millimeter to 0.3
Millimeter.It is 0.2 millimeter that the decorative pattern is highly optimal.The glue layer 2 is completely covered the frictional layer.The magnet layer 3 is complete
Cover the glue layer 2.
The utility model is not limited to implementation method discussed above.The description of specific embodiment is intended to above for
The technical scheme that description and explanation the utility model are related to.Obvious conversion or replacement based on the utility model enlightenment
Should also be as being considered within protection domain of the present utility model.More than specific embodiment be used for disclose it is of the present utility model most
Good implementation, to enable one of ordinary skill in the art using numerous embodiments of the present utility model and various
Alternative reaches the purpose of this utility model.
