The motor comprises a front end cover, a back end cover, a shell, a bearing, a hall sensor, a stator, a rotor, a winding and a rotary shaft, wherein the front end cover and the back end cover are connected with the shell separately; the rotary shaft is mounted on the front end cover and the back end cover through a bearing; the hall sensor is mounted on the shell; the winding and the rotor are mounted on the rotary shaft; the winding and the stator are arranged in opposite; and the winding is a flat dual-layer winding. Compared with the prior art, the non-cogging motor has the advantages of more tidy conductor arrangement, good performance, high universality, and the like.
Description
Technical field
The present invention relates to a kind of non-gullet motor, especially relate to a kind of non-gullet motor with low distortion winding.
Background technology
Slotless brshless DC motor has rotating speed height, slotless torque, the features such as rotor inertia is little, is widely used in electric tool, robot and among medical apparatus and instruments.The winding of non-gullet motor is different from conventional motors winding process, therefore becomes the emphasis that industry is paid close attention to.
Non-gullet motor has bigger winding space relative to conventional motors, traditional winding manufacturing process can be divided into three parts, first the wire of every phase winding is wound on a hexagonal winding mould, form three-phase windings, then pass through compacting and winding is pressed into flat, finally along cylinder, the winding of flat being rolled into a drag cup winding, winding can be connected into star-like or triangle link.
The method can not effective relative position between pilot and wire when suppressing wire, it is easy to wire is subjected to displacement, each phase winding back-emf can be caused inconsistent.Method is had to propose to use the adhesive tape of viscosity to suppress after fixing for outside winding before pressing at present again, but when winding is in multilamellar situation it cannot be guaranteed that the conductor position of winding la m.
Summary of the invention
Defect that the purpose of the present invention is contemplated to overcome above-mentioned prior art to exist and the non-gullet motor with low distortion winding that a kind of conductor arrangement is more neat, excellent performance, versatility are good is provided.
The purpose of the present invention can be achieved through the following technical solutions:
A kind of non-gullet motor with low distortion winding, including drive end bearing bracket, rear end cap, shell, bearing, Hall element, stator, rotor, winding and rotating shaft, described drive end bearing bracket and rear end cap are connected with shell respectively, described rotating shaft is arranged on by bearing on drive end bearing bracket and rear end cap, described Hall element is arranged on shell, and described winding and rotor are arranged in rotating shaft, and described winding and stator are oppositely arranged, it is characterized in that, described winding is flat Double Layer Winding.
Described flat Double Layer Winding is formed by winding mould coiling by three-phase conductor, and described three-phase conductor is wound on winding mould successively by three-phase 120 °, forms three facies tracts.
Described winding mould includes bobbin and two end faces, and described bobbin is located between two end faces.
The conductor of described winding mould side is positioned at same layer, and opposite side conductor is positioned at other one layer.
The adjustable length of described facies tract.
The lead-out wire of every phase winding connects according to star or triangle.
Compared with prior art, the invention have the advantages that
1) adopting the flat winding of this structure coiling, in the process of compacting, conductor is subjected to displacement few with deformation ratio traditional approach, and conductor arrangement is more neat；
2) adopting the winding of this structure coiling, phase resistance and the back-emf of each phase winding are more symmetrical；
3) span of winding is variable, it is possible to optimize span, reduces winding resistance, optimizes efficiency；
4) this Design of Dies is simple, it is possible to coiling various outer diameter, the drag cup winding of the number of turn, has versatility.
