Description
Technical field
The present invention relates to technical field of motors, and in particular to a kind of split type stator core manufacture craft of wheel hub motor.
Background technology
In advocating environment protection and today of energy-conservation, the motor vehicle for developing zero-emission is trend of the times.Electric automobile is to motor
Volume and energy-conservation have higher requirement, and each parts optimize to light and efficient direction.Especially in wheel hub motor, by
It is loaded directly into the weight of wheel hub motor under automotive hub, therefore its having a great influence for vehicle performance, it is desirable to its quality is more
Gently, volume is smaller and the electric energy of autophage is also smaller.So wheel hub motor stator winding often uses split-type structural, will
Stator winding is divided into multiple stator cores, is finally stitched together to form a complete stator winding, the stator core just by
Multiple stator lamination stackings form, but stator core does not often reach requirement when making.
The content of the invention
It is an object of the invention to provide it is a kind of it is simple for production, make the split type stator of the high wheel hub motor of finished product accuracy
Fabrication of iron core technique.
In order to achieve the above object, the technical solution adopted by the present invention is：Wheel hub motor makes of split type stator core
Technique, described stator core are formed by multiple punching closed assemblies, comprised the following steps：
Stator punching is made, makes multiple stator punchings according to specifications parameter, the stator punching uses tack silicon steel
Piece；
Closed assembly, multiple stator punchings are subjected to clamping with lamination stack mold, multiple stator punchings after closed assembly is formed one complete
Whole stator core；
One-time detection, detects whether the stator core after closed assembly meets design requirement；
It is heating and curing, will detects and be heating and curing in qualified stator core feeding baking oven, temperature is 190 °~210 °, the time
For 1.5~2.5 hours；
Cooling, stator core is taken out from baking oven, naturally cools to normal temperature, stator core is taken from lamination stack mold
Under；
Secondary detection, detect whether stator core meets design requirement again.
The beneficial effects of the invention are as follows：By using this manufacture craft, it can make what the stator core after shaping more consolidated
Meanwhile the total quality of stator core is ensure that, reduce the consumption of motor itself, improve operating efficiency, reduce stator
The disqualification rate of iron core.
Brief description of the drawings
Fig. 1 is stator laminating structure schematic diagram.
Fig. 2 is the stator core construction schematic diagram that is formed after stator lamination stacking.
In figure：1st, stator punching；2nd, stator core.
Embodiment
The present invention is further elaborated below in conjunction with the accompanying drawings.
As shown in Figure 1 to Figure 2, wheel hub motor stator winding often uses split-type structural, i.e., is divided into stator winding more
Individual stator core 2, winds wire on stator core 2, finally stator core 2 is being stitched together to form a complete stator
Winding, the stator core 2 are just formed by multiple closed assemblies of stator punching 1.
The invention provides a kind of wheel hub motor with split type stator core manufacture craft, and described stator core is by multiple
Punching closed assembly forms, and the technique comprises the following steps：
1st, stator punching is made；Multiple stator punchings 1 are made according to specifications parameter, described specifications parameter is according to different
Wheel hub motor model is different and different, does not do specific limitation here, and the stator punching 1 uses tack silicon steel sheet.
2nd, closed assembly；Multiple stator punchings 1 are subjected to clamping with lamination stack mold, i.e., stator punching 1 are subjected to closed assembly up and down, institute
The lamination stack mold stated is used for the stator punching firm grip after closed assembly, so that following process makes, here not to lamination stack mold
Do specific elaboration, multiple stator punchings 1 after closed assembly form a complete stator core 2.
3rd, one-time detection；Whether the stator core after detection closed assembly meets design requirement, can detect the height of stator core
Whether degree, perpendicularity, flatness meet regulation requirement.
4th, it is heating and curing；It will detect in last step and be heating and curing in qualified stator core feeding baking oven, temperature is
190 °~210 °, the time is 1.5~2.5 hours；Preferably temperature uses 200 °, and the time is 2 hours.
5th, cool down,；Stator core is taken out from baking oven, normal temperature is naturally cooled to, by stator core from lamination stack mold
Remove.
6th, secondary detection, detect whether stator core meets design requirement again.
The present invention is not limited to examples detailed above, in claims of the present invention limited range, art technology
The various deformations or amendments that personnel can make without creative work are protected by this patent.
