Description
Technical field
The invention belongs to the manufacture method of stator in a kind of motor, relate to the improvement that this stator structure makes, more specifically, which propose a kind of combining structure of motor stator core, with the technique simplifying the coiling of winding and winding, magnetic pole stem stem assembles on stator.
Background technology
At present, motor stator is formed primarily of iron core and winding.Iron core is laminated by multilayer lamination, every layer of lamination is the all-in-one-piece laminated structure that planform is identical, usually, its periphery is rendered as a closed annular, the inner side of loop configuration, radially extend internally and be formed with some magnetic pole stem stems, the inner of each magnetic pole stem stem all guides and banking stop with magnetic, and some windings are wrapped on some magnetic pole stem stems respectively.
The motor stator of this structure, the winding mode of its winding has two kinds of methods: a kind of method be after first coiling winding again toward the gap of magnetic pole core intercolumniation by artificial inlet wire and fixing winding, another kind of method adopts special coiling machinery or directly on each magnetic pole stem stem of stator core, carries out coiling by circle by the method for craft.
In these two kinds of methods, there is the low or winding of winding winding efficiency and troublesome problem is installed, simultaneously, also all there is the lower deficiency of winding copper factor, product cost is not only caused to be difficult to decline, product price remains high, and affects the speed of production in enormous quantities, and is unfavorable for that further miniaturization and power of motor further improve motor.
Summary of the invention
The object of the present invention is to provide a kind of manufacture craft of motor stator, it is a kind of combining structure for iron core proposes, its winding can independent coiling, and can be assembled together when iron core is assembled, to improve the operating efficiency of winding coiling and winding installation, meanwhile, can improve the copper factor of winding, further miniaturization and power of motor further improve to be beneficial to motor.
Object of the present invention is realized by following scheme:
A manufacture craft for motor stator, is characterized in that, comprises the following steps:
Adopt an outer shroud iron core, outer shroud iron core is laminated by outer shroud lamination, and in closed loop configuration, outer shroud iron core is provided with several Connection Blocks in inner side;
Adopt several magnetic pole stem stems, magnetic pole stem stem is laminated by stem stem lamination, and magnetic pole stem stem the inner forms magnetic guiding and spacing wing, and magnetic pole stem stem outer end is formed as the connector that can coordinate with Connection Block;
Several windings are adopted to be wound on respectively in the winding slot of several coil holders;
By connector, the upper stem stem body between the inner and outer end of magnetic pole stem stem of several magnetic pole stem stems, penetrate the through hole in the middle of several coil holders respectively, respective core cylinder is made to be arranged in corresponding through hole, and respective core cylinder is subject to the restriction of corresponding through hole, the connector of respective poles stem stem is then passed by corresponding through hole, is exposed at the outside of corresponding coil holder;
Snapped in several Connection Blocks of outer shroud iron core by the connector of several magnetic pole stem stems respectively, magnetic pole stem stem, coil holder and winding are assemblied in the inner side of outer shroud iron core.
Like this, a magnetic pole stem stem, a coil holder and a winding just can form a unit, some unit can be assembled one by one and are fixed in the inner side of outer shroud iron core, particularly, first in the wire casing of coil holder, peripherally can carry out winding coiling, being inserted by magnetic pole stem stem is more subsequently fixed in the through hole of coil holder, is finally inserted the Connection Block of outer shroud iron core by the connector of magnetic pole stem stem, then can complete the assembling of winding and stator.
So, by rotating coil holder, coiling can be carried out easily on coil holder
,simple common coiling machinery can be adopted to realize, and need not adopt special coiling machinery, can reduce the requirement to coiling machinery, meanwhile, the speed of its coiling obviously have also been obtained raising.
Simultaneously, winding ties up on coil holder and is directly wound around, then just load magnetic pole stem stem, thus each coil holder can be wound around the enough enamelled wires of the number of turn to improve copper factor, overcome the relation adopting special coiling machinery due to wire winding, need to reserve wider gap between magnetic pole stem stem and the reduction that causes copper factor.
Moreover, magnetic pole stem stem carries out combining and being connected with the grafting of Connection Block by connector with outer shroud iron core system, thus its operation is also more simple, can overcome tradition and adopt artificial inlet wire to limit due to the gap of magnetic pole core intercolumniation, be not easy winding to put the defects such as magnetic pole stem stem.
In addition, when a certain winding breaks down, because the connector of winding by magnetic pole stem stem pulls away from the Connection Block of outer shroud iron core, therefore, maintenance or replacing winding also will become very simple and convenient.
The manufacture craft of motor stator of the present invention, it produces more simple and convenient, the operating efficiency of winding coiling and winding installation can be improved, be conducive to the raising of production in enormous quantities speed, simultaneously, can improve the copper factor of winding, further miniaturization and power of motor further improve to be conducive to motor.
In scheme, the connection of the connector of magnetic pole stem stem and the Connection Block of outer shroud iron core, can adopt swallow-tail form to coordinate with dovetail groove, or cylindrically coordinates with cylinder groove, or the various ways such as projection and groove fit is carried out, then can as long as make connector Snap joint seat mutually not depart from.
