Abstract
The utility model relates to the motor manufacturing field, and discloses an insulation structure of a motor stator notch. The insulation structure comprises a stator slot, is characterized in that groove-shaped insulating paper is embedded into two ends of the stator slot, and is further improved in the way that the cross sections at the two end parts of the stator slot are larger than that in the middle, or L-shaped steps are formed at the two end parts of the stator slot. By adopting the above structure, the insulation damage of the motor stator notch can be reduced, so as to further reduce the incidence of grounded short circuit of a motor.
Description
Technical field
The utility model relates to field of motor manufacturing, particularly a kind of insulation system of motor stator notch.
Background technology
In the use of motor, ground short circuit is one of major failure of motor, and the main cause that the ground connection open circuit fault takes place is ageing of insulation or breakage.The inventor finds that the damage in insulation of motor stator notch is the one of the main reasons that causes the ground connection open circuit fault.For above-mentioned technical problem, the inventor thinks that the reason of damage in insulation of motor stator notch is, in the motor manufacture process, due to the mechanism of the corner angle of the end of stator winding and stator slot end.
Summary of the invention
The purpose of the utility model is to provide a kind of insulation system of motor stator notch, can reduce the damage in insulation of motor stator notch, and then reduces the probability that the motor ground short circuit takes place.
In order to achieve the above object, the utility model adopts following technical scheme to be achieved.
A kind of insulation system of motor stator notch comprises stator slot, it is characterized in that, two ends are embedded with groove typed insulation paper in stator slot.
The further improvement of the utility model is that the cross section at the both ends of said stator slot is greater than the cross section at middle part; Perhaps the both ends of stator slot are provided with L type step.
In the utility model, be embedded with groove typed insulation paper at stator slot, groove typed insulation paper can prevent that the mechanism of corner angle of end and the stator slot end of stator winding from destroying the overhang insulation of stator winding.In addition, the both ends cross section of stator slot is greater than middle cross section, can further cushion the mechanism of corner angle of end and the stator slot end of stator winding, reduces the damage in insulation of motor stator notch, and then reduces the probability that the motor ground short circuit takes place.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is explained further details.
Fig. 1 is the end view of a stator slot;
Fig. 2 is the A-A cutaway view of Fig. 1.
Embodiment
The insulation system of the motor stator notch of the utility model, its basic embodiment is: be embedded with groove typed insulation paper at the stator slot two ends.Groove typed insulation paper can cushion the mechanism of corner angle of end and the stator slot end of stator winding, plays the effect of protection stator winding.
With reference to Fig. 1, Fig. 2; Be the preferred embodiment of the utility model, wherein, the both ends of stator slot are provided with L type step; Make the cross section at both ends of stator slot greater than the cross section at middle part, can cushion the mechanism of corner angle of end and the stator slot end of stator winding to a greater degree.
Although more than combine accompanying drawing that the embodiment of the utility model is described, the utility model is not limited to above-mentioned specific embodiments and applications field, and above-mentioned specific embodiments only is schematic, guiding, rather than restrictive.Those of ordinary skill in the art under the situation that does not break away from the scope that the utility model claim protected, can also make a variety of forms under the enlightenment of this specification, these all belong to the row of the utility model protection.
