Abstract
The utility model discloses a motor core for electric tricycle or sewing machine, including multilayer stacking iron core piece circlewise, the iron core piece is the ribbon, and it builds up multi -storied annular structure to convolute through the heliciform, and the inboard circumference of following of iron core piece evenly is equipped with tooth portion, forms the slot part between the adjacent tooth portion, makes each layer tooth portion align each other, and the slot part figure of every layer of iron core piece is the multiple of 3 below 18. The utility model discloses in mainly using flute profile motor core's in other use in electric tricycle, sewing machine etc. Electrical apparatus and equipment, its mode through coiling superposes the iron core piece and forms the motor core of in -band tooth, can reduce the loss of raw and other materials on the one hand, improves material utilization rate, practices thrift manufacturing cost, just changes force -bearing mode, can increase motor core's intensity, on the other hand the utility model discloses to the little number of slots, the design of the motor core of big camber, can with electrical apparatus or equipment adaptations such as electric tricycle, sewing machine, targeted.
Description
Technical field
The utility model is related to a kind of electric machine iron core, refers in particular to a kind of for electro-tricycle or the motor iron of sewing machine
Core.
Background technology
Existing electric machine iron core, using traditional monolithic technology is rushed, the material unshakable in one's determination that the direct punching of silicon steel plate is circularized
Piece, is then superimposed to certain thickness using riveting or be welded and fixed by tablet.The stock utilization for rushing monolithic technology is 20%, is used
Above conventional method manufactures electric machine iron core, and the utilization rate and production efficiency of material is all relatively low, and intensity is poor.It is existing to be applied to
The electric machine iron core of washing machine, this kind of slot number is more, the less electric machine iron core of curvature, and because its core tooth is located at outside, it is impossible to
Electro-tricycle or sewing machine are adapted to.Therefore, the electric machine iron core of existing electro-tricycle or sewing machine has intensity difference, production
The problems such as high cost.
Utility model content
The utility model provides a kind of for electro-tricycle or the electric machine iron core of sewing machine, its object is to solve electricity
Dynamic tricycle, sewing machine etc. other use inner tooth type electric machine iron core bad adaptability, and the relatively low problem of stock utilization.
It is a kind of for electro-tricycle or the electric machine iron core of sewing machine, including multiple-layer stacked lamination circlewise is described
Lamination is ribbon, and by spirally winding the circulus of multilayer is built up, and lamination inner side is circumferentially uniformly provided with teeth portion,
Groove portion is formed between adjacent fingers, each layer teeth portion is mutually aligned, the groove portion number of every layer of lamination be the 3 of less than 18 times
Number.
Wherein, the groove portion number of every layer of lamination is 12.
Wherein, the teeth portion is T-shaped tooth.
Wherein, each layer lamination from the groove portion position on the inside of lamination by carrying out welding fabrication.
Wherein, the deep camber winding motor iron core is electro-tricycle or the electric machine iron core in sewing machine.
The utility model is mainly used in the electrical equipment and equipment such as electro-tricycle, sewing machine, and it is by way of winding
Lamination is superimposed to form the electric machine iron core with internal tooth, the loss of raw material on the one hand can be reduced, stock utilization, section is improved
About production cost, and change force way, by increasing capacitance it is possible to increase the intensity of electric machine iron core；Another aspect the utility model is directed to sulculus
Number, the electric machine iron core design of deep camber, and with interior T-shaped tooth, can be more preferable with the electrical equipment such as electro-tricycle, sewing machine or equipment
Ground adaptation, with specific aim, solves the problems, such as its electric machine iron core short life, reduces use cost.
