In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
As shown in Fig. 1 ~ 3 and Fig. 5 ~ 8, the manufacture method of the stator that the embodiment of the present invention provides, comprises the steps:
Iron core split manufacturing step, manufactures at least three and axially can laminate the split 11 forming stator core 1;
Spooling step, respectively coiling stator winding in each split 11, and make each split 11 forms each sub-winding coil 2 respectively;
Number of assembling steps, laminates formation stator vertically by each split 11 being arranged with each sub-winding coil 2, and particularly, each split 11 axially laminates and forms stator core 1, and each sub-winding coil 2 is connected in series or is connected in parallel formation stator winding.
The embodiment of the present invention, is first respectively after individually coiling in each split 11 (coiling stator winding), more each split 11 complete for coiling is laminated formation one-piece stator vertically.Due to its separately in each split 11 coiling all can have larger winding space, like this, be beneficial to the winding efficiency improving stator core 1 on the one hand, be beneficial to the copper factor improving stator on the other hand, and under the prerequisite of copper factor raising, can the copper cash forming stator winding be changed into aluminum steel, be beneficial to the material cost of saving stator; Make wire casing 100 opening on stator core 1 can design less on the one hand again, wire casing 100 even can be made to be designed to the form of approximate closed slot, and then be beneficial to the performance improving motor.Meanwhile, because each split 11 axially laminates assembling, therefore which ensure that the circularity precision of stator, and do not need between each split 11 to weld, simplify the follow-up assembling procedure after coiling, and then be beneficial to the production efficiency improving stator.
Preferably, as shown in Fig. 1 ~ 3 and Fig. 5 ~ 8, in iron core split manufacturing step, make each split 11 all have a circumference and to close and thickness is less than the sub-yoke 111 of the thickness of stator core 1 and at least one to be located on sub-yoke 111 and the thickness stator tooth 112 equal with the thickness of stator core 1;
In number of assembling steps, make each split 11 carry out vertically laminating assembling with the form that each stator tooth 112 staggers respectively mutually, and make the adjacent both sides of a stator tooth 112 of any split 11 all be respectively two stator tooths 112 in other two splits 11.On stator after finishing assembly, between any two adjacent stator tooths 112, enclose formation wire casing 100.In the present embodiment, because each sub-yoke 111 is all that circumference is closed, therefore which ensure that the circularity precision of stator, and do not need between each split 11 to weld, simplify the follow-up assembling procedure after coiling, and then be beneficial to the production efficiency improving stator.
Preferably, as shown in Fig. 1 ~ 3 and Fig. 5 ~ 8, in spooling step, make each sub-winding coil 2 be formed on the stator tooth 112 of each split 11 respectively, namely each sub-winding coil 2 is around on the stator tooth 112 of each split 11 respectively.The embodiment of the present invention, is first respectively after individually coiling on the stator tooth 112 of each split 11 (coiling stator winding), then the form that each split 11 complete for coiling is staggered respectively mutually with each stator tooth 112 is vertically laminated formation one-piece stator.Adjacent both sides due to a stator tooth 112 of a split 11 any on stator are after finishing assembly all two stator tooths 112 in other splits 11, namely on the stator assembled, the stator tooth 112 of same split 11 is non-conterminous settings, therefore, any one stator tooth 112 both sides in each split 11 before assembling all have larger activity space, thus make separately on the stator tooth 112 of each split 11 coiling all can have larger winding space, like this, be beneficial to the winding efficiency improving stator core 1 on the one hand, be beneficial to the copper factor improving stator on the other hand, and under the prerequisite of copper factor raising, can the copper cash forming stator winding be changed into aluminum steel, be beneficial to the material cost of saving stator, make wire casing 100 opening on stator core 1 can design less on the one hand again, wire casing 100 even can be made to be designed to the form of approximate closed slot, and then be beneficial to the performance improving motor.Meanwhile, because each sub-yoke 111 is all that circumference is closed, therefore which ensure that the circularity precision of stator, and do not need between each split 11 to weld, simplify the follow-up assembling procedure after coiling, and then be beneficial to the production efficiency improving stator.
