Description
Technical field
The present invention relates to a kind of motor, especially relate to a kind of stator winding structure and disc-type coreless permanent magnet motor of disc-type coreless permanent magnet motor.
Background technology
In the disc-type coreless permanent magnet motor of three-phase, coil windings in motor stator at least needs 3 pairs of lead-out wires and is connected could normally works with external circuit, therefore, coil windings needs that the positive integer of 3 coil doubly is superimposed could be used, because each coil itself has certain thickness, especially when needing the power of motor larger, then need the coil of more number to carry out the coiling number of turns that is superimposed or increase single coil to realize, make the thickness of the coil windings be built up larger, thus make the volume of the stator produced larger, increase the volume of motor.Simultaneously, motor operationally, the two sides that rotor is arranged on stator are rotated, what can utilize during machine operation is the magnetic field that the straightway of each coil and epitrochanterian magnet steel corresponding part and magnet are strafed limit and produced, because each coil in coil windings and rotor normally be arranged in parallel, therefore, the magnetic field produced away from the coil of rotor can become more weak when arriving rotor, make the magnetic utilance of motor lower, the Motor torque produced is little, and there are differences due to the distance between each coil in coil windings and the rotor of both sides, technical staff is difficult to the actual power demand size accurately designing motor.Also have, due to the loop configuration that the single coil being built up coil windings is all plane, namely to strafe limit equal for inside and outside invalid edges and the magnet of coil, therefore the coil windings be built up is after being injection molded into stator, the outer edge portion of coil windings cannot coordinate with the inside and outside convex shape of stator, makes the structural strength of the stator be injection molded into poor.
Summary of the invention
The magnet that the invention provides a kind of each coil is strafed limit and is positioned at same plane and the stator winding structure of highly consistent disc-type coreless permanent magnet motor, make the motor volume produced less, the utilance in magnetic field is high, and the power of motor can careful design according to actual needs; Solve the brushless coreless disc-type permanent magnet motor volume existed in prior art utilance power that is low and motor that is comparatively large, magnetic field and be difficult to the technical problem of careful design etc.
Above-mentioned technical problem of the present invention is mainly solved by following technical proposals: a kind of stator winding structure of disc-type coreless permanent magnet motor, it is characterized in that: this winding at least includes 3 groups of angles and laminate successively along clockwise direction and form the unit coil groups of closed ring structure of staggering downwards, constituent parts coil groups includes 2 stagger angle and the coils upwards laminated successively along clockwise direction, each coil includes a pair magnet for straightway and strafes limit and be connected to magnet and strafe outer end in limit and make coil form in closed ring structure, outer invalid edges, the magnet of each coil is strafed edge circumference arranged radially and is distributed on same anchor ring, and magnet all in winding is strafed limit and is positioned at same plane and highly consistent, in each coil, outer invalid edges respectively relatively each self-corresponding magnet is strafed limit and is bent up and down to arrange mutually to laminate simultaneously and form opposed magnet and to strafe on limit in lower convexity, outer superimposed portion.By magnet all in winding being strafed limit and is arranged to be positioned at same plane and highly consistent, in winding, magnet is strafed limit and is equivalent to only have a Rotating fields, the magnet of each coil is strafed edge circumference arranged radially distribution and is formed anchor ring, therefore, when using with rotor engagement, often pair of magnet in winding strafe limit produce arrival both sides, magnetic field rotor time intensity be identical, realize magnet magnet strafe limit strafe area maximize, thus make the electromagnetic field utilance of the tankful rate of coil and generation higher, substantially increase the efficiency of motor, decrease the caloric value of motor stator, the useful life of the motor of further raising, the inside and outside invalid edges of each coil respectively relatively each self-corresponding magnet is strafed limit and is bent up and down to arrange mutually to laminate simultaneously and form the inside and outside superimposed portion that opposed magnet strafes lower convexity on limit, therefore, the winding construction formed is fitted mutually with the structure of stator, inside and outside superimposed portion is as the forming skeleton of stator inside and outside, and the stator of injection moulding or form has good intensity, each magnet in the present invention is strafed limit and to be in same plane and highly consistent, the height in inside and outside superimposed portion is also far smaller than existing multiple coil and puts down folded thickness, therefore, the thickness of the stator utilizing the present invention to produce reduces greatly, can realize batch production and the application of powerful brushless coreless disc-type permanent magnet motor, simultaneously, the relatively each self-corresponding magnet of outer invalid edges due to each coil is strafed after limit bends up and down and is laminated the outer superimposed portion of formation, therefore, the external diameter laminating the winding of formation reduces further, be conducive to reducing the volume of stator and the corresponding motor utilizing it to make, the relatively each self-corresponding magnet of interior invalid edges of each coil is strafed after limit bends up and down and is laminated superimposed portion in formation, increase the internal diameter of winding, greater room is left to the endoporus of motor stator, add the main axe intensity be located in stator inner hole, strengthen the stability of rotor.Simultaneously, because the present invention to be staggered angle and laminate downwards successively along clockwise direction and form closed ring structure each other by the unit coil groups of 3 groups or more, unit coil groups includes 2 stagger angle and the coils upwards laminated successively along clockwise direction, therefore, each coil is when being superimposed with each other, the outer invalid edges of each coil can not overlap together mutually, mutual extruding between the outer invalid edges reducing each coil, prevent distortion, after superimposed between coil, the magnet of each coil is strafed limit and can be remained in same plane preferably, and precision is high.
As preferably, angle superimposed between angle superimposed between adjacent unit coil groups with the adjacent windings in unit coil groups is identical, and between adjacent windings in unit coil groups, superimposed angle is that on coil, every pair of magnet strafes 1/3 of limit self angle.Therefore, the angle that adjacent magnets between two in winding strafes limit formation is identical, each magnet strafe Bian Qi arrangement formed anchor ring in be radially uniformly distributed, the angle that each magnet is strafed between limit is identical, ensure that the consistency of integral greatly, the area of strafing that magnet strafes limit maximizes, thus makes the electromagnetic field utilance of the tankful rate of winding and generation higher, makes the power of motor can careful design according to actual needs.
