Abstract
The invention relates to a motor stator coil with a novel transposition structure. The coil comprises a first coil unit, a second coil unit and row insulation. Each of the coil units is of a single-unit single-row structure which is made of wounded electromagnetic wires. The outer lead of the first coil unit is connected with the inner lead of the second coil unit, so a single-unit double-row coil is formed. The row insulation is arranged on the outer sides of the coil units. According to the invention, just by connecting the outer lead of the first coil unit with the inner lead of the second coil unit, the single-unit double-row coil can be formed with no need for bending the electromagnetic wires, so disadvantages in the arch transposition technology can be fundamentally removed.
Description
Technical field
The present invention relates to field of motor manufacturing, particularly relate to a kind of coil of stator of motor of novel transposition structure.
Background technology
Energy-efficient compact(ing) machine will be the future developing trend of motor product, the manufacture level of motor coil is the key technology of motor, direct design parameter, reliability and the holistic cost affecting motor, determine price and the quality of motor, in order to reduce the volume of stator, transposition technology is proposed in coil manufacture, this technology can significantly reduce coil single stack height, namely the winding structure of current potential equivalence is adopted to be converted to by single single-row winding single double, thus improve the utilization ratio of stator core, reduce volume, reduce costs.
The most frequently used is " arc transposition " technology in the prior art, and this technology is mainly for the manufacture of single double coil, and the method for its transposition is, in shuttle-type end, electromagnetic wire is bent to its adjacent row from when front row, realizes single double effect.The shortcoming of this technology has: 1, this bending easily causes transposition damage in insulation; 2, because exchange point can not be overlapped in a place, then when coil turn is more or coil-end length is shorter, transposition space may be not enough, causes realizing single two-row structure; 3, when electromagnetic wire wire gauge is less, the deformation of electromagnetic wire bending place is difficult to control, and causes the size of coil bending place when the type that rises not ensure, cannot complete coil and to rise type.
Summary of the invention
The object of the invention is to overcome above defect, provide a kind of make simple, insulation is reliable, the coil of stator of motor of compact conformation.
In order to solve the problems of the technologies described above, technical scheme of the present invention is, a kind of coil of stator of motor of novel transposition structure, it comprises First Line coil unit, the second coil unit, bar insulation, described coil unit is the single single row configuration coil that single electromagnetic wire turns to, the outer lead of First Line coil unit is connected with the lead of the second coil unit, and form a single double coil, described bar insulation is located at the outside of coil unit.
Preferably, the outer lead of described First Line coil unit and the lead of the second coil unit weld together.
Preferably, the material of described bar insulation is polyester film-backed dry mica tape or polyimide film reinforcement dry mica paper tape.
Preferably, the thickness of described bar insulation is 0.1mm to 0.4mm.
Advantageous Effects of the present invention is, owing to only needing to be connected by the lead of the outer lead of First Line coil unit with the second coil unit, a single double coil can be formed, thus do not need to bend electromagnetic wire, fundamentally can solve the defect of arc transposition technology.
