The stator module of Chinese patent application number 200310106783.3 disclosed a kind of linear electric motors comprises: external stator and internal stator; Described external stator comprises: winding body, several magnetic core arrays, two utmost point seats and magnetic core retainer ring; Described winding body is hollow ring, and inside is inlaid with coil; Described magnetic core array is formed by stacking by the stator magnet chip, radially is inserted in respectively on the lateral surface of winding body; Described utmost point seat is inserted in the both sides of winding body inner peripheral surface respectively, and its outer peripheral face contacts with the inner face of each magnetic core array respectively; Described magnetic core retainer ring lock ring is on the outer face of each magnetic core array.It is said that this beneficial effect of the invention is: rational in infrastructure, thus simplified the packaging technology of magnetic core array greatly, not only reduce production cost, and improved reliability of products.But this stator module still needs to carry out the internal tooth coiling when coiling, cost is still higher.
The utility model content
The purpose of this utility model aims to provide a kind of simple and reasonable, the stator module that can save the punching material, enhance productivity, to overcome weak point of the prior art.
Press the stator module of a kind of three-phase brushless dc motor of this purpose design, comprise stator punching and iron core, its architectural feature is that stator module is made by several discrete core insulation assemblies welding.
Described discrete core insulation assembly comprises discrete punching, last Insulating frame, following Insulating frame and terminal pin; Wherein discrete punching is a T shape or I-shaped, and its left and right sides is respectively arranged with tooth and the groove that is meshed, and 12 discrete punchings become a circular stator punching by the tooth that matches with groove combination.
Described upward Insulating frame, following Insulating frame, discrete punching and terminal pin match fixing in aggregates, make discrete core insulation assembly in its outside coiling.It is upright that four discrete core insulation assemblies turn to the single-phase stator group, and three groups of single-phase stator groups are upright, and to be shaped to the threephase stator group by frock upright.
With tooth and the groove combination circular stator module of 12 discrete core insulation assemblies by being meshed in the discrete punching, and fixing at tooth and groove junction with the argon arc welding welding.
The utility model is simple and reasonable, adopts the form of discrete punching, has changed traditional internal tooth wire winding.Because this product is with the upright part of stator pack, it is upright to make earlier the single-phase stator group respectively, and then it is upright to be combined into the threephase stator group, therefore can be with common external tooth flying trident coil winding machine replacement internal tooth coil winding machine, raising threading speed, optimize the coiling winding displacement, improve copper factor, promote electric efficiency and production efficiency, replace circular punching with discrete punching simultaneously and can effectively utilize material, save motor cost, be fit to produce in enormous quantities.
