Description

High efficiency motor same core enameled wire winding construction

Technical field

The utility model is related to a kind of not only safety in utilization is good, but also that winding mode is simple, embedding is efficient is efficient Motor same core enameled wire winding construction, belongs to threephase asynchronous machine manufacturing field.

Background technology

103503278 A of CN, title " a kind of stator ", have a stator core of coil and Splittable, the coil pass through by Wrapping conductors and formed and possess slot inner lead and end turn conducting wire, the stator core of the Splittable, which has, stores the slot The slot of inner lead and tooth that is adjacent with the slot and being formed, the stator are characterized in that the coil has：First same core Winding coil, the first same core winding coil is formed as same core winding, and has between the adjacent conductor of winding The gap that can be inserted into for the conductor；And the second same core winding coil, the second same core winding coil and described first Same core winding coil is similarly wound, in the slot, the slot inner lead of the first same core winding coil with it is described The slot inner lead of second same core winding coil is alternately arranged, in the end turn of the first same core winding coil The route transformation component formed at conducting wire is formed to avoid in the end turn conducting wire of the second same core winding coil The width of one of the conductor used.A kind of manufacturing method for stators, the manufacturing method for stators form wrapping conductors Possess the coil of slot inner lead and end turn conducting wire, the coil in caged is configured and forms coil cage, will be provided with tooth Stator core with the Splittable of slot is inserted into the coil cage, so as to form substantially circular stator, the stator system The method of making is characterized in that, by the coil to have what can be inserted into for conductor other described between the adjacent conductor The mode in gap is formed as same core winding, on the end turn conducting wire in a manner of the width of one for avoiding the conductor Route transformation component is formed, forms coil cage using the coil, the coil cage is with will be inside the slot of the first same core winding coil The slot inner lead of conducting wire and the second same core winding coil being adjacent to the first same core winding coil is inserted into each other The gap in and the mode that is alternately arranged be configured to annular shape, by the tooth of the stator core from the coil cage Peripheral side is inserted into the coil cage, is consequently formed the stator.It is disadvantageous in that：First, this kind of stator insulation effect Generally, safety in utilization is poor；Second is that the flatness error of this kind of stator caulking groove both sides cell wall is larger, so as to add stator Embedding difficulty, and then affect the embedding efficiency of stator.

Utility model content

Purpose of design：To avoid the deficiency in background technology, a kind of not only safety in utilization of design is good, but also winding mode Simply, the efficient high efficiency motor same core enameled wire winding construction of embedding.

Designing scheme：To realize above-mentioned purpose of design.1st, the first semicanal and the second semicanal and first are equipped in the caulking groove Semicanal and the second semicanal wrap the design of the same core winding line segment in caulking groove after closing up, be that the technology of the utility model is special One of sign.The purpose so designed is：First, close up rear first semicanal and the second semicanal to the same core winding that is located in caulking groove Line segment plays the role of being dielectrically separated from, so as to ensure the safety in utilization of motor；Second is that the same core winding line segment in caulking groove It is wrapped up using separable first semicanal and the second semicanal so that same core winding can be time saving and energy saving is mounted on stator iron In the caulking groove of core.2nd, first semicanal and the second semicanal are made of insulating materials and the pipe thickness of the first semicanal is 0.25 Mm -3.5mm, the second semicanal pipe thickness be 0.45 mm -0.55mm design, be the technical characteristics of the utility model it Two.The purpose so designed is：First, the pipe thickness of the first semicanal is 0.25 mm -3.5mm, the first semicanal of the thickness The difficulty of same core winding line segment insertion caulking groove will not be improved（It is generated when hardly increasing same core winding line segment insertion caulking groove embedding Enter resistance）, while the first semicanal of the thickness can be ensured that the insulation effect of the first semicanal；Second is that the pipe thickness of the second semicanal For 0.45 mm -0.55mm, the second semicanal of the thickness not only has good insulation effect, but also the second semicanal pair of thickness Caulking groove plays the role of interference filling so that same core winding line segment more consolidation is inlaid in caulking groove.3rd, it is described to be made the first half The insulating materials of pipe or the second semicanal is the design of 6641 polymer composites, is the three of the technical characteristics of the utility model. The purpose so designed is：6641 polymer composites have many advantages, such as that good insulating, wearability are good, density is small so that Not only safety in utilization is good for winding construction, but also quality is lighter.4th, the stator core front end face is provided with dowel hole and positioning Pin hole penetrates through stator core rear and front end face, and the design of positioning pin is equipped in the dowel hole, is the technology of the utility model The four of feature.The purpose so designed is：Since stator is to be laminated to form by multi-disc stator piece, laminated by multi-disc stator piece The stator front end face of composition is provided with dowel hole and positioning pin is worn in dowel hole, can so improve the concentric of stator piece Degree（Improve the flatness of caulking groove both sides cell wall）, so that the embedding technology of same core winding becomes easier, and then improve The embedding efficiency of same core winding.

Technical solution：A kind of high efficiency motor same core enameled wire winding construction including stator core and is inlaid in stator core Same core winding in caulking groove is equipped with the first semicanal and the second semicanal in the caulking groove and the first semicanal and the second semicanal closes up Hou Bao Wrap the same core winding line segment in caulking groove.

The utility model is compared with background technology, first, the first semicanal and in high efficiency motor same core enameled wire winding construction The setting of two semicanals not only plays insulation protection to same core winding, but also makes the same core winding wire being located in caulking groove The embedded more consolidation of section；Second is that the dowel hole added in high efficiency motor same core enameled wire winding construction, can improve caulking groove two The flatness of side channel wall, so as to improve the embedding efficiency of same core winding.
