Abstract
The utility model discloses a kind of stator core and motor in axial magnetic field, the stator core includes stator disc, with the multiple teeth portion extended from the end face direction perpendicular to the stator disc, the corner of each teeth portion is provided with fillet, and winding coil is close to the teeth portion setting.The turning of the teeth portion of stator core in the utility model is provided with fillet, therefore, stator core is when being arranged winding coil, teeth portion turning is that rounded structure is not easy to scratch winding coil, very little can be set in gap between winding coil and teeth portion, the volume for the winding coil that ensure that, the volume without will affect entire motor, improves the volumetric power density of motor compared with prior art.
Description
Technical field
The utility model relates to technical field of motors, more specifically to a kind of stator core and axial magnetic field electricity
Machine.
Background technique
Currently, the stator core of motor in axial magnetic field includes multiple teeth portion, each do not refer to is provided with winding coil, each
Four angles of teeth portion are wedge angles, in order to avoid four wedge angles of teeth portion scratch coil, so between coil and the interior outside of teeth portion
There are biggish gaps, and therefore, the end of winding coil is suitably exaggerated, so electric machine casing will also amplify, make electricity
The overall volume of machine increases, and volumetric power density reduces.
Utility model content
In view of this, technical problem to be solved in the utility model is how to improve the volumetric power density of motor, it is
This, the utility model provides a kind of stator core and motor in axial magnetic field.
To achieve the above object, the utility model provides the following technical solutions:
A kind of stator core, comprising: stator disc, and the multiple teeth extended from the end face direction perpendicular to the stator disc
Portion, the corner of each teeth portion are provided with fillet, and winding coil is close to the teeth portion setting.
In the utility model one embodiment, the stator core is by silicon-steel sheet coiled around forming.
In the utility model one embodiment, the teeth portion is tetragonous rod structure.
The invention also discloses a kind of motor in axial magnetic field, the motor in axial magnetic field includes such as any of the above-described institute
The stator core stated.
It can be seen from the above technical scheme that the turning of the teeth portion of the stator core in the utility model is provided with circle
Angle, therefore, for stator core when winding coil is arranged, teeth portion turning is that rounded structure is not easy to scratch winding coil, winding coil
Very little can be set in gap between teeth portion, the volume for the winding coil that ensure that, the volume without will affect entire motor,
The volumetric power density of motor is improved compared with prior art.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, in the premise not made the creative labor
Under, it is also possible to obtain other drawings based on these drawings.

In figure, 500 it is stator core, 600 is winding coil, 501 is stator disc, 502 is teeth portion, 503 is fillet.
Specific embodiment
The core of the utility model is to provide a kind of stator core and motor in axial magnetic field, to improve the volume of motor
Power density.
In addition, embodiments illustrated below does not play any restriction effect to utility model content documented by claim.
In addition, the full content of composition represented by following example is not limited to the solution as utility model documented by claim
Necessary to scheme.
Please refer to Fig. 1 to Fig. 2, the stator core 500 in the utility model embodiment, comprising: stator disc 501, and hang down certainly
The multiple teeth portion 502 directly extended in the end face direction of stator disc 501, the corner of each teeth portion 502 are provided with fillet 503, around
Group coil 600 is close to teeth portion 502 and is arranged.The turning of the teeth portion 502 of stator core 500 in the utility model is provided with fillet
503, therefore, for stator core 500 when winding coil 600 is arranged, 502 turning of teeth portion is that 503 structure of fillet is not easy to scratch winding
Very little can be set in coil 600, the gap between winding coil 600 and teeth portion 502, the volume for the winding coil 600 that ensure that,
Volume without will affect entire motor, improves the volumetric power density of motor compared with prior art.
It should be noted that the stator core 500 in the utility model is formed by silicon steel plate stacking or stator core
500 by silicon-steel sheet coiled around forming.
Teeth portion 502 is triangular prism structure, tetragonous rod structure, etc. when for tetragonous rod structure, teeth portion 502 is close to stator iron
The middle part of core 500 width be less than teeth portion 502 be located at outside while width.
The invention also discloses a kind of motor in axial magnetic field, the motor in axial magnetic field includes such as any of the above-described institute
The stator core stated.Since said stator iron core has the above effect, the motor in axial magnetic field including said stator iron core has
Corresponding effect, details are not described herein again.
The foregoing description of the disclosed embodiments can be realized professional and technical personnel in the field or using originally practical new
Type.Various modifications to these embodiments will be readily apparent to those skilled in the art, and determine herein
The General Principle of justice can be realized in other embodiments without departing from the spirit or scope of the present utility model.Cause
This, the present invention will not be limited to the embodiments shown herein, and is to fit to and principles disclosed herein
The widest scope consistent with features of novelty.
