Description
Technical field
The present invention relates to motor, more particularly to winding slot is located at the motor stator on the outside of silicon steel sheet.
Background technology
The stator winding of external rotor electric machine is to be inlaid in the inner side of silicon steel sheet towards rotor one end in the prior art, still
The copper factor of the wire casing of coiling stator winding is than relatively low in this motor stator, because the frock of this stator need to be incited somebody to action by inside groove
Line is wound in groove, thus the space that frock passes through must be left in groove, can only manual winding when motor needs bigger power
And increase copper factor.
The content of the invention
The present invention is directed to disadvantages mentioned above, there is provided a kind of outer coiling electric motor stator and the motor with outer wound stator.
In order to solve the above-mentioned technical problem, the present invention is addressed by following technical proposals：
Outer coiling electric motor stator, including silicon steel sheet, silicon steel sheet outer radial are provided with winding slot, and the cell wall of winding slot is provided with
Plastic layer, stator winding is wound with winding slot.
Preferably, also including ring, silicon steel sheet is located at the inside of ring.Ring plays protection nonferromagnetic material inner ring and silicon steel sheet
The effect of group.
Preferably, plastic layer is BMC layer.BMC (BMC) is a kind of thermosetting plastics, wherein mixed
Various inert fillers, fibre reinforced materials, catalyst, stabilizer and pigment have been closed, has formed a kind of glue for compression moulding or injection
Viscous " putty-like " composite.
Preferably, ring is silicon steel loop.
Preferably, the madial wall of ring is provided with upper groove, upper groove communicates with winding slot.
Preferably, being additionally provided with low groove on silicon steel sheet, low groove is located at coiling trench bottom.Upper groove and low groove can be with
Wire is preferably contained in winding slot will not be shifted over, while set low groove to facilitate wire winding tool from low groove
In by improving winding efficiency.
Preferably, silicon steel sheet is grain-oriented Si steel sheet.The performance of the general silicon steel sheet of grain-oriented Si steel sheet wall is more preferable.
Motor with outer wound stator, including outer coiling electric motor stator.
The present invention by set on silicon steel sheet outside winding slot by stator winding on silicon steel sheet it is outer around so as to improve
The winding efficiency of the stator of induction machine or brushless electric machine, reduces the cost of labor of production motor, while improves induced electricity
Machine or the copper factor of brushless motor stator coiling, improve the moment of torsion of motor.
