The stator is composed by the conducting magnetic steel strip wound around the circumferential motor, the surface thereof facing against the rotor is provided with a crosswise groove whose inner is compressed with the stator coils. The motor of the utility model is provided with good dynamic performance, good use of the magnetic circuit, light weight and small axial size, which is particularly suitable for the small-covering generating group with small power machine.
Description
Technical field
The utility model relates to plane axial magnetic field permanent magnet motor, more particularly, relates to the radial armature slot axial magnetic field permanent magnetic motor of a kind of multilayer planar type commentaries on classics, stator.
Background technology
Magnetic pole and winding some defective on layout of existing planographic winding electric machine, air gap is big, and effective flux is little, and magnetic resistance is big, the magnetic loss height, efficient is low.
Summary of the invention
The purpose of this utility model provides a kind of structure that has simple rotor to cooperate, and axial dimension is little, and dynamic index is good, is particularly suitable for cooperating the minitype motivation machine to make the magneto of generating set.
The utility model reaches the utility model purpose by the following technical programs:
A kind of planar radial armature slot axial magnetic field permanent magnetic motor, stator and rotor face one another axially-aligned, and the permanent magnets at a plurality of alternating polarities of rotor surface circumferential arrangement of facing stator is characterized in that rotor is a dish type, and it is fan-shaped or trapezoidal that permanent magnets is; Described stator core is made of the magnetic conducting band of circumferentially reeling at motor, with the right surface of rotor cover on the width of cloth to establishing tooth and groove, embed stator coil in the groove; When the stator facewidth is b, when groove width was a, each pole-face width was n * b+ (n-1) * a, n=1--3 wherein, a/b=0.9--1.
The utility model motor volume is little, and is in light weight, magnetic circuit utilance height, and power performance is good, and become the generator unit to take up an area of with minitype motivation mechanism little.Energy output exceeds more than 6～10 times than motor motor with weight under equal output condition of routine.
Description of drawings
Fig. 1 is that the motor shaft of the utility model embodiment is to cross-sectional schematic.
Fig. 2 is the local stator core end view of the motor of the utility model embodiment.
Fig. 3 is the local stator core perspective view of the motor of the utility model embodiment.
Fig. 4 is the local rotor end-face view of the motor of the utility model embodiment.

Embodiment
Describe the utility model embodiment in detail below with reference to accompanying drawing.Fig. 1 is the axial cross-sectional schematic of the motor of the utility model embodiment.Fig. 2, the 3rd, the figure of the local stator core of expression.Fig. 4 is the schematic diagram that the rotor permanent-magnet pole distributes.Fig. 5 is that one deck of this routine motor launches schematic diagram along the circumference part.Wherein 1 is rotor, the 2nd, stator, stator and rotor distribute vertically in this example, rotor 1 is positioned at the stator both sides, be that rotor has left and right two parts, two end faces of therebetween stator respectively with above-mentioned about the end face trapping crack of two rotors relative, constitute one deck rotor, this routine motor has the such formation of multilayer to be formed by stacking.Stator 2 is by the steel band of circumferentially reeling around motor, silicon strip for example, and constituting, on its both ends of the surface, offer the width of cloth to uniform groove 21, see Fig. 2,3, set subcoil 22 (see figure 5)s in the groove.In this example the motor outermost end be rotor, two end face that is in outermost end is a magnetic conduction matter disk 11.Can be that stator is in the generator outermost end, do not establish teeth groove on the outermost stator faces this moment yet.And multilayer when stack (see figure 1) is arranged when motor, the disk of inner rotator part adopts non-magnetic conduction conductor formation (to see Fig. 1,11 ＇), all with rotor cover that stator is faced mutually on be fan-shaped or trapezoidal permanent magnetism sheet 12 with (for example being bonded with) is a plurality of, change along circumferential alternating polarity.Different every the pole polarity of stator face-off on the left and right rotor portion, the steel band magnetic aligning that stator is reeled is axial.When the stator facewidth is b, when groove width was a, each pole-face width was n * b+ (n-1) * a, n=1--3 wherein, a/b=0.9--1.Three teeth and two grooves on the corresponding stator of magnetic pole pole-face in this example, the facewidth equals groove width, i.e. n=3, a/b=1.The stator coil on left and right both sides can constitute two stator winding, and these two stator winding can be independent of separately drawing, and also can draw behind series/parallel.
About on the described same rotor disk same position two dorsad the permanent magnets on the face can pass rotor disk and form with a permanent magnets.
Present embodiment can be made some and be revised and change, and for example, every layer of left and right rotor portion is identical every the pole polarity of stator face-off, and correspondingly, when the stator steel band, making its magnetic aligning is that motor is circumferential.
The utility model is particularly suitable for the occasion of multipole number, for example 10 pairs extremely more than.
The utility model illustrates with embodiment, but should not be limited to this, and persons skilled in the art can be according to this explanation and it is modified or changes, and these modifications or change also should be included in the utility model design scope.
